Scope
JB/T 12223-2015 is the English-translated version of 封闭式离心制冷机用三相异步电动机技术条件.
JB/T 12223-2015 is the Chinese machinery industry standard for the three-phase asynchronous motors built into closed centrifugal refrigerators. It states the types, basic parameters and dimensions, technical requirements, inspection rules, marking, packaging and warranty for such motors.
Its field of application is motors for enclosed centrifugal refrigerators using R123 and R134a as the cooling refrigerant; motors derived from the series, and motors for refrigerators working with other refrigerants, may follow it by reference.
Among the standards it quotes are GB 755-2008, GB/T 1032-2012, GB 10068-2008, GB/T 13501-2008, GB/T 22714-2008 and JB/T 9058-1999. The record places it under Chinese classification K22 and ICS 29.160.30.
