1.1 This practice is divided into 4 parts A, B, C, and D. 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.
1.2 The scope of Part A can be found in Section 4.
1.3 The scope of Part B can be found in Section 13.
1.4 The scope of Part C can be found in Section 19.
1.5 The scope of Part D can be found in Section 32.
1.6 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use. For specific hazard statements, see Sections 7, 39.1.6, 21,
1.4, and 38.1.1.
