JB/T 3914-2026 is the English-translated version of 超硬磨料取样方法.

JB/T 3914-2026 is a method standard that describes how samples of superabrasive material are taken. Sampling is the first step before any testing of grain properties or quality, and the document gives a common procedure so that the sample tested represents the lot supplied.

It is used by superabrasive manufacturers, by test laboratories that receive and prepare samples, and by buyers who verify deliveries against agreed specifications. It is a voluntary standard, as shown by the /T in its code. It was approved and issued by the Ministry of Industry and Information Technology on 1 June 2026 and takes effect on 1 December 2026. It replaces JB/T 3914-2012.
