JB/T 15280-2026Magnetic moment block (English PDF)

JB/T 15280-2026 is the English-translated version of 磁矩块.

JB/T 15280-2026 is the product standard for the magnetic moment block, a magnetic component made from electrical alloy material. It sets out the requirements for this product so that makers and users work from the same description of what a magnetic moment block is and what it must meet.

The document is used by producers of magnetic alloy parts, by manufacturers of electrical and magnetic devices that use the component, and by buyers and test laboratories that check it on receipt. It is a voluntary industry standard, as the /T in its code indicates. It was issued by the Ministry of Industry and Information Technology on 13 February 2026 and takes effect on 1 September 2026. It is a new standard.
