SN/T 4369-2015 in English

This standard outlines a method for determining the presence and concentration of specific elements in imported and exported coal. The method involves the use of microwave digestion followed by inductively coupled plasma mass spectrometry. It provides detailed procedures for sample preparation, digestion, and analysis, ensuring accurate and reliable results. The standard is applicable to a range of elements, including but not limited to arsenic, mercury, lead, cadmium, chromium, and beryllium. It serves as a reference for laboratories and testing institutions involved in the analysis of coal samples for compliance with regulatory requirements. The procedures described are designed to be efficient and suitable for routine testing applications.
