Zalewski Subject: CONSOLIDATION OF SPECIFICATIONS PVC PITE FORMULAS (M.S. 455-5) AND MIXING PROCEDURES (M.S. 455-6) A proposed revision to Manufacturing Spec ``55-6, J-M PVC ripe Mixing Procedures, was issued for review and comments on 12/15/76. This revision was an attempt to rewrite the spec to authorize equal or better alternate equipment and methods currently used by several plants, but not included in the specification. Comments from, uhe plants now indicate more areas that fit into this category. A' see r, 5 review of Manufacturing Spec 455-6, J-M PVC Pipe Mixing Procedures, wests that mast of the information in this ::r-: serves no useful purpose and does not belong in a Manufacturing Spec.
