SPEC. 455-5 PVC FORMULAS iU--" June 19, 1974 At' Attached is the proposed major revision of the PVC Formulation spec. We intend to issue it on July 1st with August 1st as the effective date. Please review the proposed spec, and make any corrections or comments that you feel are appropriate. I would appreciate having your feedback as far in advance of the scheduled July 1st issue date as possible. Of course, if major revisions are required, we can easily enough change the date of issue; but the current 455-5 is so obsolete that the revision should be out to the plants as soon as possible. /rc Attachment MTC 010592 J- J1 is if: - !' , V* .... .V?
