Performance Evaluation of Point Type Smoke/Temperature Detector

1 Scope

GB/Z 24979-2010 is the Chinese national standard on performance assessment of point type smoke and/or heat fire detector, in the field of environment and health protection, safety. The /Z suffix marks it as a guiding technical document: it does not prescribe requirements that can be certified against, but sets out the technique, the method or the state of the art that the standards bodies recommend following. It was issued on 9 August 2010 by the State Administration for Market Regulation; Standardization Administration of China. As a guiding technical document it carries no separate date of entry into force: it applies from publication. Classification: ICS 13.220.20, CCS C81. 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 issuing body are taken from there. The clause text, the tables and the numeric limits are in the document itself, which is delivered complete in English translation.

This guideline gives the evaluation process and evaluation method of performance evaluation of point-type smoke/thermal-fire detector. This instructional technical document is applicable to point-type smoke detectors, point-type temperature detectors, point-type smoke temperature composite fire detectors, It provides guidelines for the performance evaluation of point-type smoke/thermal-fire detectors. This guidance document is also applicable to the performance evaluation of point-type smoke, point-type temperature sensing and point-type smoke temperature composite fire detection algorithm.
