IS 18932 : 2024 Electronic Expansion Valve - Specification
1 SCOPE
1.1 This standard specifies the performance, safety requirements, and test methods for electrically driven type electronic expansion valves with nominal supply voltage not more than 36 V d.c., with orifice diameter up to 8 mm used in refrigeration and air conditioning cycle. This standard also specifies marking, packing, storage condition, and transportation requirements.
1.2 This standard does not specify the requirements for toxic refrigerants [refrigerants with higher toxicity (B1, B2L, B2, and B3) as per IS 16656, like ammonia].
