QB/T 4976-2026Particular requirements for transportation of room air-conditioner employed the flammable refrigerants (English PDF)

QB/T 4976-2026 is the English-translated version of 使用可燃性制冷剂房间空调器运输的特殊要求.

QB/T 4976-2026 sets out particular requirements for the transportation of room air conditioners that use flammable refrigerants. It concerns the carriage of these appliances once they are made, from the factory or warehouse to the point of sale or installation. The word particular in the title shows that the document applies to the special case in which the refrigerant is flammable, and it does not address the manufacture, installation or repair of the appliances. It is a product standard of the Ministry of Industry and Information Technology.

Air conditioner manufacturers, distributors, freight and logistics companies and drivers, as well as inspection bodies, would refer to it. It is a voluntary standard, as shown by the /T in its code. It was issued on 13 February 2026 and takes effect on 1 September 2026. It replaces QB/T 4976-2016.
