未冷却示踪气体和电子煤气泄露探测器最低性能要求

[中文适用范围]： 该标准提供了泄漏检测设备所需的测试和功能要求指南，该设备使用任何非空调制冷剂示踪气体@（例如氦气或氮氢混合物@）来提供与制冷剂电子泄漏检测器相当的功能性能。它解释了如何建立非制冷剂检漏仪的校准，以提供与满足 R-134a 的 SAE J2791 和 R-1234yf 的 SAE J2913 要求的电子检漏仪相同的检测水平。 [外文原描述]： This SAE Standard provides the testing and functional requirements guidance necessary for a leak detection device that uses any non-A/C refrigerant tracer gas, such as helium or a nitrogen-hydrogen blend, to provide functional performance equivalent to a refrigerant electronic leak detector. It explains how a non-refrigerant leak detector’s calibration can be established to provide levels of detection equal to electronic leak detectors that meet SAE J2791 for R-134a and SAE J2913 for R-1234yf.Cross Reference: J2197,J2670,J2791_201903,J2888_201902,J2911_201612,J2913_201610
