1 Scope This standard specifies test methods of lead and cadmium content in automobiles materials. "X-ray fluorescence spectrometry" is applicable to screening and fast determining the lead and cadmium content in automobiles materials. "Optical emission spectrometric method for determination of lead and cadmium in steel and iron, copper and copper alloy, and aluminum and aluminum alloy materials" is applicable to quantitative determination of lead and cadmium content in steel and iron, copper and copper alloy, and aluminum and aluminum alloy rod or bulk materials in automobiles materials. "Atomic absorption spectrometry, inductively coupled plasma atomic emission spectrometry or inductively coupled plasma mass spectrometry for determination of lead and cadmium content in automobiles materials" is applicable to quantitative determination of lead and cadmium content in automobiles materials. 2 Normative References The following referenced documents are indispensable for the application of this document.
