1.1 This practice is divided into 4 parts. These 4 parts represent the previous standards D7256\/D7256M , D4916 , D4702 , and D6518 . These 4 standards are the 4 that govern the mechanical sampling of coal and have been combined into one document for the ease of reference of the users of these standards.<\/p>\n
