Scope
GB 15930-2024 is the English-translated version of 建筑通风和排烟系统用防火阀门.
GB 15930 is the product standard for the dampers that close a ventilation duct when fire reaches it, and for the ones that stay open to vent smoke.
It classifies them by function and fire resistance, sets the nominal dimensions and the model designation, then the construction, the closing mechanism and its thermal or electrical release, the leakage and the fire resistance in terms of integrity and, where required, insulation, together with the operating cycles, the test methods and the inspection rules.
A damper that fails to close breaches a fire compartment through its own ductwork, which is why it is mandatory. Issued on 28 November 2024, in force since 1 March 2026, replacing GB 15930-2007.
This page is published from the official record of the standard held by the Chinese standards administration: the identification, the dates, the classification and the edition it replaces are taken from there.
The clause text, the tables and the numeric limits are not reproduced on this page — they are in the document itself, which is delivered in full in English translation.
