Scope
JB/T 1544-2015 is the English-translated version of 电气绝缘浸渍漆和漆布快速热老化试验方法-热重点斜法.
JB/T 1544-2015 is a recommended Chinese machinery industry standard laying down a rapid thermal ageing test method for electrical insulating impregnating varnishes and varnished fabrics, worked by the thermogravimetric point slope technique.
It is used to run that rapid ageing test on these materials and to obtain from it the temperature index, written td, and the equation of the thermal life line that expresses their heat resistance.
The standard states that the method is not a substitute for the conventional thermal ageing methods. It quotes GB/T 1408.1-2006, GB/T 11026.4-2012 and GB/T 27749-2011.
The document replaces the earlier edition JB/T 1544-1999 and carries the Chinese classification K15.
