1 Scope This standard specifies the inductively coupled plasma emission spectroscopy method1) for determination of total content of nine heavy metals, including lead (Pb), cadmium (Cd), nickel (Ni), chromium (Cr), cobalt (Co), copper (Cu), stibium (Sb), arsenic (As) and hydrargyrum (Hg) in footwear product and component. This standard is applicable to all footwear and footwear components. Table 1 in GB/T 29292-2012 specifies the materials containing these substances. 2 Normative References The following referenced documents are indispensable for the application of this document.
