摘要
测试用标准样品的稳定在感烟火灾探测器检测中具有关键性的作用。本文提出了一种科学有效的标准样品选取方案。利用环境加速试验,考评待测样品在环境加速试验前后的重复性和均匀性,从而得到性能最稳定的标准样品。同时,本文探索了标准样品的新型应用,该样品可用于离子烟浓度计的计量方案设计中。该研究可大大减少选样周期,评估方法科学可靠,可为火灾报警产品检测实验室提供标准样,同时解决了测试用离子烟浓度计计量难的问题。
The stability of the standard sample plays a key role in the testing of the smoke detectors.A scientific and effective standard sample selection scheme is proposed in this paper.The repeatability and uniformity of the tested samples are evaluated before and after the environmental acceleration testing,and the most stable standard sample is obtained.At the same time,this paper explores the new application of the standard sample,which can be used in the calibration of the measuring ionization chamber(MIC).This work can greatly reduce the selection time and provide the standard samples for the laboratory of the smoke detectors testing which is scientific and reliable.At the same time,the difficult problem of the calibration of the measuring ionization chamber(MIC)is solved here.
