Scope

JB/T 12723-2016 is the English-translated version of 热变形/维卡软化温度测定仪技术规范.

JB/T 12723-2016 is the recommended Chinese machinery industry standard for heat deflection temperature and Vicat softening temperature testers. It specifies their technical requirements, the inspection methods and the inspection rules, and then marking, packaging, transport, storage and the documents supplied with the instrument.

The testers covered work in a liquid bath and measure the load deflection temperature and the Vicat softening temperature of plastics, hard rubber and products made from them.

It quotes GB/T 1633-2000, GB/T 1634.1-2004, GB/T 2611-2007 and JB/T 6147-2007. The standard carries the Chinese classification N72 and the ICS codes 17.060 and 19.060.
