1.1 These test methods cover two procedures for the qualitative determination and identification of the mineral constituents of filled and coated papers.
1.2 Due to the similarity in chemical composition and physical size and shape of some of the various possible constituents contained in a given paper specimen, more precise, quantitative methods may at times be required for positive identification.
1.3 It is recommended that one become thoroughly familiar with these test methods by analyzing paper samples of known mineral component content.
1.4 The test methods appear as follows:
Sections Method A-Chemical Analysis 4 to 11 Method B-Microscopical Identification 12 to 191.5 This standard does not purport to address all of the safety problems, 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.
