    1. Rationale

    A new document has been added that references C 780 and C 270 and helps clarify their purposes and uses. Add C 1586 to the standard as a reference and place a note for it under the scope. Renumber subsequent notes as necessary. 1. Scope * 1.1 This test method covers procedures for the sampling and testing of mortars for composition and for their plastic and hardened properties, either before or during their actual use in construction. Note 1: The Standard Guide for Quality Assurance of Mortars, C 1586, provides guidance on evaluating mortar and clarifies the purpose of both C 780 and C 270, the Specification for Mortar for Unit Masonry. 2. Referenced Documents 2.1 ASTM Standards: C 1586 Standard Guide for Quality Assurance of Mortars
