Scope

Replace 5th paragraph with:This standard does not take into account refrigerants other than safety group A1, A2L, A2 and A3 as defined by ISO 817. For refrigerant blends where dual classification exists in ISO 817, the classification based on WCF is used. Flammable refrigerants are limited to those of a molar mass of more than or equal to 42 kg/kmol as specified in ISO 817. For refrigerant blends the molar mass shall be based on WCF (worst case formulation).NOTE 101 Where dual classification exists in ISO 817, the WCF is the least restrictive of the classifications.NOTE 102 The tables with ISO 817 refrigerant data are provided at https://standards.iso.org/iso/817/ma/en/.Renumber the previous NOTE 103 and NOTE 104.
