These proposed changes for C 497/497M are being made to clarify the procedures for measuring gasket dimensions and replacing burdensome, unpractical procedures with methods being currently practiced by manufacturers and required by certification programs. See current Note 8 These are measurements performed by the pipe manufacturer for quality control checks. Also, these changes include the addition of some QC checks that were not previously included in the Standards.
