INTER-OFFICE MEMO TENNECO CHEMICALS, INC. \ to G.I, Rozand fromW.C. Champion subject Revised Grading Procedures at Piscataway at Burlington date February 20, 1974 copy to P. Gawason H.R. Horton F.W. Kanzler R^A. Fojewski ^fTLe Grading procedures for both resin and compound have been reviewed with the objective of reducing the amount of "Special Product" (i.e., ungraded) handling. The attached table provides current practice and recommended changes for achieving this end. For resins, the changes will include grading of all LOP and SPA materials. This will require (especially for LOP where in-specification product is Grade I and out-of-specification product is not graded) a more rapid re sponse in changing manufacturing specifications as required. In compound, much of the "Special Production" is simply new color matches. Since standards are established for each new color prior to production, these products can be graded. For certain compounds, a "IS" grade similar to that employed in plastisol would be useful in showing that a run will meet customer requirements even though not meeting out internal manufactur ing standards. If you concur in these recommendations, I will take the action required to put them into effect. Attachment. WCC/jst W.C. Champion1 COLORITE 012516 COLORITE 012517 RESIN GRADI! PROCEDURES Type of Production Normal Suspension Production Procedure Graded I or* E in accordance with established manufacturing spec ifications. Normal Plastisol Production Graded I, IS or E in accordance with established manufacturing specifications. Limited Operating Procedure (LOP) Minor process, formula change or substitution of equivalent raw material. Not intended to change product properties. ' Graded I if meets manufacturing specifications. Not graded ("Special Production") if outof-specification. Standard Product Adjustment (SPA) Minor changes in process, formula or raw materials which are intended to change product properties. Not graded ("Special Production") New Product Introduction (NPI) Production of a product substantially different from any in our current product line. Not graded ("Special Production") Recommendation No change No change Grade all LOP material in accordance with manufacturing specifications. Revise specifications as required.

Subsequent runs graded ac cording to established spec ifications. Not graded by Quality Control ("Special Production") Recommendation ^. J No change, or regrade to "IS" desig nation where a specific customer has less stringent requirements (Note: This would not apply to such requirements as contamination or oversize,) Grade I or E by Quality Control according to established manufac turing specifications. Release by R&D, Grade I or E according to specifica tions established in the SPA. Re lease by R&D/Marketing. No change No change Grade as standard compound.
