Scope
QB/T 8198-2026 is the English-translated version of 锁体.
QB/T 8198-2026 is the light industry standard for the lock body, the main housing and mechanism part of a door lock that holds the bolt and the internal working parts. The document treats the lock body as a product and sets out the technical provisions that apply to it, so that manufacturers, assemblers and buyers can refer to a single published text when they describe and assess this component.
The standard is aimed at lock manufacturers, producers of door hardware who build lock bodies into complete lock sets, test laboratories and inspection bodies, building and hardware distributors, and purchasers who write supply specifications. It is voluntary, as the /T in its code shows, and becomes binding in practice only when a contract, a customer or another rule makes it so. The Ministry of Industry and Information Technology approved and issued it on 13 February 2026, and it takes effect on 1 September 2026. It is a new document and does not replace an earlier edition.
