标准摘要
[中文适用范围]： 本文档规定了用于确定滤器元件泄漏的‘扫描法’测试程序，该方法被视为参考方法。适用于从ISO 35 H到ISO 75 U等级的过滤器。它还描述了其他规范性方法，即油线泄漏测试（见附录A）和光度计泄漏测试（见附录B），适用于ISO 35 H至ISO 45 H等级的HEPA过滤器，以及固体PSL气溶胶泄漏测试（见附录E）。该方法旨在与ISO 29463-1、ISO 29463-2、ISO 29463-3和ISO 29463-5配合使用。 [外文原描述]： ISO 29463-4:2011 specifies the test procedure of the "scan method", considered to be the reference method, for determining the leakage of filter elements. It is applicable to filters ranging from classes ISO 35 H to ISO 75 U. ISO 29463-4:2011 also describes the other normative methods: the oil thread leak test and the photometer leak test, applicable to classes ISO 35 H to ISO 45 H HEPA filters, and the leak test with solid PSL aerosol. ISO 29463-4:2011 is intended for use in conjunction with ISO 29463-1, ISO 29463-2, ISO 29463-3 and ISO 29463-5.
