GB/T 3785的本部分规定了设计符合IEC 61672-1中要求的1级和2级规范的时间计权声级计、积分平均声级计和积分声级计的周期试验程序。其目的是保证所有实验室采用一致的方法进行周期试验。 周期试验的目的是为了向用户证明,对于限定的一组关键试验和在进行试验的环境条件下,声级计的性能满足IEC 61672-1适用的规范。 本部分中试验的范围是慎重有意的限制到周期试验所必需的最小范围。 本部分适用于生产商宣称符合IEC 61672-1第2版规范的声级计。本部分中周期试验也适用于其型号已经或者还未由独立试验机构按照IEC 61672-2第2版试验程序进行型式批准试验的声级计。 由于周期试验的范围有限,如果不能公开获得型式评价的证据,即便周期试验的结果符合IEC 61672-3本版本的所有适用要求,也不能做出符合IEC 61672-1规范的总结论。
