masonry mortars, the testing laboratory performing the test methods
should be accredited in accordance with Practice C 1093.
The proportion or property specifications shall govern as
specified.
When neither proportion or property specifications are

are presented to and accepted by the specifier to show that mortar
meets the requirements of the property specifications.
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
