Standard Specification for Mortar for Unit Masonry

SCOPE
1.1 This specification covers mortars for use in the construction of non-reinforced and reinforced unit masonry structures. Four types of mortar are covered in each of two alternative specifications: (1) proportion specifications and (2) property specifications.
Note 1—- When the property specification is used to qualify masonry mortars, the testing laboratory performing the test methods should be accredited in accordance with Practice C 1093.
1.2 The proportion or property specifications shall govern as specified.
1.3 When neither proportion or property specifications are specified, the proportion specifications shall govern, unless data are presented to and accepted by the specifier to show that mortar meets the requirements of the property specifications.
1.4 The text of this specification references notes and footnotes which provide explanatory material. These notes and footnotes (excluding those in tables and figures) shall not be considered as requirements of the standard.
1.5 The terms used in this specification are identified in Terminologies C 1180 and C 1232.
1.6 The following safety hazards caveat pertains only to the test methods section of this specification: 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.
