1 Scope This standard gives methods for determining mercury content in automobile parts and materials. X-ray fluorescence spectrometry is applicable to screening and rapid determination of mercury content in automobile materials. Cold atomic absorption spectrometry, atomic fluorescence spectrometry, inductively coupled plasma atomic emission spectrometry or inductively coupled plasma mass spectrometry is applicable to quantitative determination of mercury content in automobile materials. Direct mercury determination is applicable to quantitative determination of mercury content in automobile materials. 2 Normative References The following referenced documents are indispensable for the application of this document.
