1.1This test method covers procedures for petrographic examination and chemical analysis of samples of masonry mortars. Based upon such examination and analysis, proportions of components in masonry mortars can be determined.

1.2Interpretations and calculations of chemical results are dependent upon results of the petrographic examination. The use of the chemical results alone is contrary to the requirements of this test method.

1.3Procedures for sampling, petrographic examination, chemical analysis, and calculations of component proportions are given in the following sections:

1.4The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.

1.5The text of this standard references notes and footnotes that provide explanatory material. These notes and footnotes (excluding those in tables and figures) shall not be considered as requirements of the standard.

1.6This standard does not purport to address all of the safety concerns, if any, associated with its use.
