It was reported to the Task Group that, contrary to paragraph 3.1 of C270, the improper use of Specification C270 Property Specifications requirements to evaluate construction site-produced mortars continues. Consequently, it was felt by the Task Group that moving paragraph 3.1 of C270 from the specifications limitations section into to the Scope will better clarify the requirements of C270 on this matter. The paragraphs in Sections 1 and 3 were renumbered accordingly.
