Scope

1.1 This specification covers the requirements for fully formulated glycol-based coolants used in a fuel cell electric vehicle (FCEV).

1.2 Coolants are designed for use in systems where the coolant is in contact with the fuel cell stack.

1.3 The coolant may be used in systems designed for use in a fuel cell vehicle equipped with an ion exchange resin to maintain low electrical conductivity.

1.4 Coolants in this specification shall be used as supplied and need no further dilution by the user.

1.5 Coolants shall protect against corrosion, freezing, and overheating.

1.6 Coolants may circulate within the vehicle fuel cell stack, battery, or other vehicle components, or may circulate through a cooling plate heat exchanger used to remove heat from batteries and other electrical components. Cooling plates consist of a metal plate constructed with passages for the coolant to circulate.

1.7 Coolants manage heat loads within the vehicle, prevent thermal runaway, and may serve to either cool or heat the batteries or electrical components.

1.8 Coolants shall be fully compatible with all system components in which they are in contact, including metals, polymers, and elastomers.

1.9 Coolants shall not be mixed with or contaminated by a different coolant type.

1.10 Coolants may be used in non-vehicle applications. The requirements for non-vehicle applications are not addressed by this standard.

1.11 Units—The values stated in SI units are to be regarded as standard.

1.12 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.

1.13 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
