GB/T 38287-2019 《Determination of hexavalent chromium in plastic materials》 Related products
This standard specifies two methods for the determination of hexavalent chromium content in plastic materials: diphenylcarbazide Spectrophotometric method, spectrophotometry and liquid chromatograph Inductance coupled plasma Mass spectrometry. It is suitable for the detection of hexavalent chromium content in various plastic raw materials and products. The standard explains the possible interference factors in the detection and provides specific operation steps to ensure the accuracy and Reliability of the test results. These methods provide an important basis for the quality control and environmental protection testing of plastic products.
