Title
Standard Test Methods of Qualitative Examination of Mineral Filler and Mineral Coating of Paper

ASTM International

Publication Date:
Sep 15, 1993

Scope:

These test methods cover two procedures for the qualitative determination and identification of the mineral constituents of filled and coated papers.

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.

It is recommended that one become thoroughly familiar with these test methods by analyzing paper samples of known mineral component content.

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.

NOTE 1—These test methods are technically equivalent to TAPPI T 421.
