标准摘要
[中文适用范围]： 本国际标准规定了用于检测和定位装有内燃机的道路车辆排气系统中气体泄漏的氦气测试方法，以提高废气测量的质量。 在此过程中，它满足了 ISO 3929、适用法规的要求，并且根据要检测的泄漏率，满足了 ISO 13556 的要求。 该方法特别适用于汽车车间、汽车和排气部件的生产线末端制造商、废气排放测试前的实验室以及测试和诊断站。 [外文原描述]： ISO 16247:2004 specifies a helium test method for detecting and localising gas leaks in the exhaust systems of road vehicles equipped with an internal combustion engine, in order to improve the quality of exhaust gas measurements. In doing so, it completes the requirements of ISO 3929, applicable regulations and, depending on the leak rate for detection, ISO 13556. The method is particularly applicable for use in automotive workshops, by end-of-line of automotive and exhaust parts manufacturers, in laboratories prior to exhaust emission tests, and in testing and diagnosis stations.
