Revision of F3441-23 Standard Guide for Measurement of pH Below Resilient Flooring Installations


During the November 2022 meeting of the F06 Committee, there was language recommended to change and expand the verbiage of paragraph 13.1. This ballot item covers only the new wording proposed for that paragraph. As a reminder, the Guide already discusses at what level liquid water may exist in the capillary and pore structure of a concrete slab (85%) within Note 2, the proposed new language incorporates that discussion into the interpretation of results.
