1.1 These requirements cover an alternate approach to specifying through air and over surface spacings for electrical equipment through the use of the principles of insulation coordination.

1.2 The complete principles of insulation coordination involve the consideration of the combination of clearances, creepage distances, and the properties of solid insulation used to constitute the insulation system. The empirical data gathered thus far has been used to develop the requirements for clearances and creepage distances as presented in this standard. The data needed to develop the evaluation procedure for solid insulation is still being gathered. When available, this evaluation procedure will be added to this standard and is not expected to affect the requirements for clearances and creepage distances.

1.3 These requirements may be used as an alternate to required spacing levels specified in end-product standards. The end product standard spacing requirements may be based on use and systems where overvoltages are not controlled, or if controlled, the level of control is unknown.

1.4 These alternate requirements are intended to be applied to a particular product category if the standard covering the product category specifically references UL 840 or any of the requirements therein.

1.5 Users of these requirements may need to specify the overvoltage levels and the methods of control which will be utilized, and establish the pollution degree to which the product insulation system will be expected to be subjected.

1.6 It is not intended that the test values in this standard be employed for production line testing. However, users of these requirements will need to establish a means to ensure that production controls applied to permit the spacing reduction remain in effect during the manufacture of the product. This could include sample testing or physical measurements or another equivalent means.

1.7 Users of these requirements will additionally need to ensure that influencing factors not addressed in this standard, such as mechanical movement, field placement of conductive material, and product damage, will not affect the system for insulation coordination. Examples are the deformation of the enclosure, movement of the fittings for conduit or armored cable, or the improper installation of field wiring. Clearances and creepage distances at those locations must be verified for compliance by physical measurement in accordance with Section 10, Measurement of Clearance and Creepage Distances.

1.1 The requirements in Part i of this Standard apply to enclosed capacitors with integral protection intended to reduce the risk of rupture and venting of the capacitor enclosure under internal fault conditions. These requirements apply to capacitors with expansion type protection rated 5 kilovolts or less, and capacitors with segmented film type protection rated 2 kilovolts or less that are intended for use with appliances, lighting equipment, air conditioning and refrigeration equipment, motors, and the like, that comply with the requirements for such appliances and equipment.

Power factor correction units with these additional features shall be evaluated to the Standard for Industrial Control Panels, UL 508A as an industrial control panel.

1.2 revised effective May 21, 2012

1.2.1 A component capacitor used in a power factor correction unit as described in Part ii of this Standard has been evaluated for across-the-line applications in accordance with Part i of this Standard and has been evaluated for a minimum fault current rating of 10K AFC.

1.2.1 revised March 3, 2008

1.2.2 The requirements of Supplement sa apply to electrolytic capacitors for motor start or similar applications including dc circuits rated 600 V or less.

1.2.2 added March 3, 2008

1.3 A capacitor that complies with the requirements in Part i of this standard is intended to be mounted within an appliance or within equipment for which an acceptable outer enclosure is provided.

1.4 The requirements in Part i and Part ii do not apply to capacitors covered by the Standard for Across-the-Line, Antenna Coupling, and Line-by-Pass Capacitors for Radio- and Television-Type Appliances, UL 1414 .

1.5 Other types of capacitors may be investigated to establish compliance with these requirements, and with such additional test criteria as may be found necessary.

1.6 A product that contains features, characteristics, components, materials, or systems new or different from those covered by the requirements in this standard, and that involves a risk of fire or of electric shock or injury to persons shall be evaluated using appropriate additional component and end-product requirements to maintain the level of safety as originally anticipated by the intent of this standard. A product whose features, characteristics, components, materials, or systems conflict with specific requirements or provisions of this standard does not comply with this standard. Revision of requirements shall be proposed and adopted in conformance with the methods employed for development, revision, and implementation of this standard.

1.5 Conditions of use of the product that are the basis for test and other evaluations in the standard are retained and applied, as far as practicable, to these products employing a battery supply.

1.6 Battery operated appliances not able to be connected to mains connected power covered by this standard are not considered to be grounded (class l) or double-insulated (class II), appliances and therefore are not required to have basic, supplementary or reinforced insulation. Electric shock hazard is considered to exist only between parts of opposite polarity.

1.7 Battery packs for appliances covered under this standard intended to be charged by a non-isolated charger are to be evaluated by this standard and the requirements for protection against electric shock of the end-product standard. When evaluating a battery pack for protection against electric shock, the construction and test requirements are to be assessed with the battery fitted to the intended charger.

1.8 When evaluating the risk of fire associated with detachable battery packs, consideration has been given to the fact that these battery packs are unattended energy sources and have been evaluated as such in this standard. Detachable battery packs evaluated by this standard are therefore considered to fulfill an effective protection against the risk of fire equivalent to that of the end-product standard.

1.9 Since battery packs for appliances are submitted to different use patterns (such as rough use, high charging and discharging currents) their safety can be evaluated only by this standard and not by using other standards for battery packs, such as the Standard for Household and Commercial Batteries, UL 2054, unless otherwise indicated in this standard.

1.10 This standard does not apply to the safety of battery chargers themselves. However, this standard covers the safe functioning of lithium-ion battery systems.

1.11 This standard also addresses requirements covering the use of lithium-ion cells employed in battery systems in appliances. The following is considered within the context of these requirements:

a)    These requirements address the risk of fire or explosion of these batteries but do not cover any possible hazards associated with toxicity nor potential hazards associated with transportation or disposal.

b)    Battery systems covered by these requirements are not intended to be serviced by the end user.

c)    These requirements are intended to provide comprehensive evaluation of a battery only if used in products covered by this standard.

d)    These requirements refer to and require parameters supplied in reference to the cells that establish conditions for safe use of those cells. Those parameters form the basis of acceptance criteria for a number of tests contained herein. This standard does not independently evaluate the safety of cells. These parameters, taken as a set, constitute the “Specified Operating Region” for a cell. There may be several sets of specified operating region(s).

1.12 This standard is not intended to apply to appliances using general purpose batteries installed by the user, and this standard alone will not be sufficient to ensure all hazards are considered for these products’ “battery packs”.

1.13 These requirements do not consider the effect of special applications (such as medical appliances) or special environments (such as hazardous locations).

1.14 These requirements have not been assessed for their suitability for product categories other than appliances such as information technology equipment, telecommunications, laboratory equipment, fire alarm, security systems, emergency lighting, and audio-video apparatus, and may be incomplete with respect to those categories.

1.15 These requirements address the safety of battery systems during storage and use including discharge and charge. These requirements are only considered to be supplementary requirements with respect to the risk of fire and electric shock in battery chargers. The safety of battery chargers for appliances are covered by other standards such as the Standard for Power Units Other Than Class 2, UL 1012, the Standard for Battery Chargers, CAN/CSA C22.2 No. 107.2, the Standard for Class 2 Power Units, UL 1310 , the Standard for Power Supplies With Extra-Low-Voltage Class 2 Outputs, CAN/CSA C22.2 No. 223, or the Standard for Information Technology Equipment – Safety – Part 1: General Requirements, UL 60950-1 and CAN/CSA C22.2 No. 60950-1.

1.16 These requirements make frequent reference to the conditions and tests of the end-product standard while also providing minimum conditions or severity of tests. These minimum conditions are not to be construed to imply equivalence to end-product requirements. Conditions or requirements of end-product standards are to prevail over the conditions or requirements of this standard, unless otherwise indicated in this standard.

1.17 This standard is not intended to cover appliances using lithium-metal type cells, and this standard alone will not be sufficient to ensure all hazards are considered for these types of cells. Lithium-ion cells are not lithium-metal cells.

Scope Summary

This standard covers the safety principles, risk mitigation, tools, techniques, and lifecycle processes for building and evaluating a safety argument for vehicles that can operate in an autonomous mode.

Operation is assumed to occur without human supervision and without expectation of human intervention in performing the dynamic driving task and other normal system operations environment. Human contributions to safety in other than normal operation are considered (e.g., pedestrians).

This New Edition of ANSI/UL 4600 dated March 15, 2022 includes the following changes in requirements:

• Revise Requirements regarding Safety Case; Section 5

• Revise Requirements for Faults, Hazards, Risks; Section 6

• Revise Requirements in Assessment; Section 3

• Revise Sensor Requirements; Section 8

• Revise Requirements for Object Tracking; Section 8

• Add requirement to 7.3.1.2 to allow unconditional on demand and safe egress by authorized operator or occupant

• Terminology updates (including change in terminology of “self-audit” to “self-assessment”)

2 Scope

2 1.1 This standard covers the safety principles, risk mitigation, tools, techniques, and lifecycle processes for building and evaluating a safety argument for vehicles that can operate in an autonomous mode.

2 1.2 Operation is assumed to occur without human supervision and without expectation of human intervention in performing and supervising the dynamic driving task and other normal system operations based upon the current item state and ability to sense and otherwise interpret the operating environment. Human contributions to safety in other than normal operation are considered (e.g., maintenance), as are interactions with humans who are not operating the item (e.g., pedestrians).

2 1.3 This standard generally uses the term “ item ” rather than “system” or “product” when referring to the scope of the safety case as well as the operation of the item . This approach is in recognition of the possibility that the safety of the item might rely upon infrastructure, services, support processes, and other factors that might not normally be considered part of a system such as a vehicle per se, but which materially affect its safety and therefore are all considered within the scope of the item being assessed forconformance.

2 1.4 This standard assumes that the item autonomously operates starting at some well-defined initial state to some other well-defined end state without human intervention. Human input might influence the selection of desirable states (e.g., via an occupant requesting a destination). However, the extent to which human operators mitigate or introduce risk by performing or supervising a dynamic control task (e.g., by driving or taking responsibility for monitoring system operation) is outside the scope of the standard. Similarly, the extent to which human operator performance or non-performance is involved in risks related to transferring human driver control to or from the item is also outside the scope of the standard. However, ensuring that the item itself properly performs any change of control functions if and when it is supposed to is generally within the scope of the standard since it can adversely affect operation in fully autonomous mode as well. Thus, while portions of this standard might be helpful for addressing less than fully autonomous vehicles, issues involving human driver responsibilities, vigilance, and ability to properly accept responsibility for vehicle control are out of scope for this standard.

2 1.5 While information security is an essential topic, the details of that area are out of scope for this standard beyond a general requirement for a Security Plan and prompt elements that are possibly unique to autonomous vehicle operation in comparison to other vehicular security requirements. Reasonably foreseeable misuse and abuse as well as physical attacks (e.g., physical sensor damage) are in scope.

2 1.6 The requirements of this standard are considered to be at a necessary, but possibly not sufficient, level of completeness and rigor to create an acceptably well-formed and acceptably complete item safety case . In particular, prompt element lists are considered non-exhaustive, with an expectation that design teams will include additional items as relevant to the item and its operational design domain

Summary of Topics

This New Edition of ANSI/UL 4600 dated March 17, 2023 includes the following changes in requirements:

• Revised safety case framework to support Autonomous Trucking

• Revised and added examples specific to Autonomous Trucking

• Added more precise definition for one preferred form of Safety Performance Indicator (SPI)

• Added requirements concerning post-incident behaviors in Sections 10.6.6 and 10.6.7

Scope

2 1.1 This standard covers the safety principles, risk mitigation, tools, techniques, and lifecycle processes for building and evaluating a safety argument for vehicles that can operate in an autonomous mode, whether the item is individual or part of a team such as a platoon

2 1.2 Operation is assumed to occur without human supervision and without expectation of human intervention in performing and supervising the dynamic driving task and other normal system operations based upon the current item state and ability to sense and otherwise interpret the operating environment. Human contributions to safety in other than normal operation are considered (e.g., maintenance), as are interactions with humans who are not operating the item (e.g., pedestrians).

2 1.3 This standard generally uses the term “ item” rather than “system” or “product” when referring to the scope of the safety case as well as the operation of the item. This approach is in recognition of the possibility that the safety of the item might rely upon infrastructure, services, support processes, and other factors that might not normally be considered part of a system such as a vehicle per se, but which materially affect its safety and therefore are all considered within the scope of the item being assessed for conformance. For a team of vehicles the item might be scoped as an individual vehicle that is a member of a team or instead the item might be designed to function as a team as a whole without reducing the safety of any one vehicle.

2 1.4 This standard assumes that the item autonomously operates starting at some well-defined initial state to some other well-defined end state without human intervention. Human input might influence the selection of desirable states (e.g., via an occupant requesting a destination). However, the extent to which human operators mitigate or introduce risk by performing or supervising a dynamic control task (e.g., by driving or taking responsibility for monitoring system operation) is outside the scope of the standard. Similarly, the extent to which human operator performance or non-performance is involved in risks related to transferring human driver control to or from the item is also outside the scope of the standard. However, ensuring that the item itself properly performs any change of control functions if and when it is supposed to is generally within the scope of the standard since it can adversely affect operation in fully autonomous mode as well. Thus, while portions of this standard might be helpful for addressing less than fully autonomous vehicles, issues involving human driver responsibilities, vigilance, and ability to properly accept responsibility for vehicle control are out of scope for this standard.

2 1.5 While information security is an essential topic, the details of that area are out of scope for this standard beyond a general requirement for a Security Plan and prompt elements that are possibly unique to autonomous vehicle operation in comparison to other vehicular security requirements. Reasonably foreseeable misuse and abuse as well as physical attacks (e.g., physical sensor damage) are in scope.

2 1.6 The requirements of this standard are considered to be at a necessary, but possibly not sufficient, level of completeness and rigor to create an acceptably well-formed and acceptably complete item safety case . In particular, prompt element lists are considered non-exhaustive , with an expectation that design teams will include additional items as relevant to the item and its operational design domain

Scope

2 1.1 This standard covers the safety principles, risk mitigation, tools, techniques, and lifecycle processes for building and evaluating a safety argument for vehicles that can operate in an autonomous mode, whether the item is individual or part of a team such as a platoon.

2 1.2 Operation is assumed to occur without human supervision and without expectation of human intervention in performing and supervising the dynamic driving task and other normal system operations based upon the current item state and ability to sense and otherwise interpret the operating environment. Human contributions to safety in other than normal operation are considered (e.g., maintenance), as are interactions with humans who are not operating the item (e.g., pedestrians).

2 1.3 This standard generally uses the term “item” rather than “system” or “product” when referring to the scope of the safety case as well as the operation of the item. This approach is in recognition of the possibility that the safety of the item might rely upon infrastructure, services, support processes, and other factors that might not normally be considered part of a system such as a vehicle per se, but which materially affect its safety and therefore are all considered within the scope of the item being assessed for conformance. For a team of vehicles the item might be scoped as an individual vehicle that is a member of a team or instead the item might be designed to function as a team as a whole without reducing the safety of any one vehicle.

2 1.4 This standard assumes that the item autonomously operates starting at some well-defined initial state to some other well-defined end state without human intervention. Human input might influence the selection of desirable states (e.g., via an occupant requesting a destination). However, the extent to which human operators mitigate or introduce risk by performing or supervising a dynamic control task (e.g., by driving or taking responsibility for monitoring system operation) is outside the scope of the standard. Similarly, the extent to which human operator performance or non-performance is involved in risks related to transferring human driver control to or from the item is also outside the scope of the standard. However, ensuring that the item itself properly performs any change of control functions if and when it is supposed to is generally within the scope of the standard since it can adversely affect operation in fully autonomous mode as well. Thus, while portions of this standard might be helpful for addressing less than fully autonomous vehicles, issues involving human driver responsibilities, vigilance, and ability to properly accept responsibility for vehicle control are out of scope for this standard.

2 1.5 While information security is an essential topic, the details of that area are out of scope for this standard beyond a general requirement for a Security Plan andprompt element  that are possibly unique to autonomous vehicle operation in comparison to other vehicular security requirements. Reasonably foreseeable misuse and abuse as well as physical attacks (e.g., physical sensor damage) are in scope.

2 1.6 The requirements of this standard are considered to be at a necessary, but possibly not sufficient, level of completeness and rigor to create an acceptably well-formed and acceptably complete item safety case .
