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:
