Scope
JB/T 4392-2011 is the English-translated version of 聚合物水溶性淬火介质测定方法.
JB/T 4392-2011 is a recommended Chinese machinery industry standard laying down test methods for polymer water-soluble quenchants. The properties it provides methods for are appearance, solid content, density, kinematic viscosity, refractive index, pour point, cloud point and pH, together with the dilution cooling curve and a rust test. Performance measurement on water-soluble polymer quenching media is what those methods are meant for. Among the standards it quotes are GB/T 265, GB/T 510, GB/T 614, GB/T 1884, GB/T 8170 and JB/T 9189. Its Chinese classification is J36 and its international classification 25.200. The document replaces the earlier edition JB/T 4392-1999.
