Included in the notes of both End Caps and Increasers is a reference to Addendum pages A-l and A-2 should dimensions for CG (old design) pipe and couplings be needed. 3) Addition of "handling label" reference to General Product Description. 4) In both Sections A and B, under the title Marking, a brief explanation as to where the "handling label" is attached.

CTD015286 Effect on Inventory; Another reminder to keep inventories of the old design 14", 15", 16" and 21" pipe, couplings, rings and fittings as low as practical to speed up the transition to the new design when it occurs. With regards to End Caps and Increasers, these inventories should also be kept as low as is practical where old design 14", 15", 16" and 21" sizes are involved.

OLD DESIGN RINGS GO WITH OLD DESIGN COUPLINGS AND NEW DESIGN RINGS GO WITH NEW DESIGN COUPLINGS ONLY. Concerning pipe and couplings, the 14" and 16" old and new designs are inter changeable provided the correct rings are used with the coupling. THE 15" AND 21" OID DESIGN PIPE SHOULD NOT BE USED WITH NEW COUPLINGS AND NEW DESIGN PIPE SHOULD NOT BE USED WITH OLD DESIGN COUPLINGS.

CertainTeed El CertainTeed Corporation Pipe and Plastics Group A/C Standard Product Specification OATE OF ISSUE: Spec. #2 T.C.O. NO.: PAGE NO.: MAR 5 1979 47 1 DESCRIPTION: FLUID-TITE A/C Sewer Pipe, Couplings and Accessories Classes 1500, 2400, 3300, 4000, 5000, 6000 and 7000 Sections A and B ,,Purpose: I I II This revision to Spec #2 Sections A and B contains many significant changes that should be thoroughly reviewed by Q.C. and manufacturing. The changes are listed below: j i j 1) Be aware that the intent at this time is to change the 14" and 16" Sewer Joint design to use a larger cross-section ring. Also 15" and 21" joints will be changed from Common Groove Sewer design to Fluid-Tite sewer. I ] These changes were mentioned in the 2-12-79 issue of Purchasing Spec. #531 (for the rings) and are repeated below: Note: 14", 15", 16" and 21" new designs are not compatible with the old couplings and therefore are not interchangeable. The old rings go with the old couplings, and the new rings with the new couplings only. 14" and 16" pipe machining was changed only a minor amount, so either the new or the old combination of rings and couplings are compatible. In 15" and 21" the pipe "C" and "X" length machining will be changed so the old pipe should not be used with the new couplings and vice-versa. Please make sure you understand so that when the new ring molds are approved and inventories are available, we can phase out the old designs and bring on the new with as few problems as possible. The 14", 15", 16" and 21" size inventories of pipe, couplings, rings and fittings should be kept as low as practical to speed up the transition when it happens. The spec, shows both the old and new versions. The old version is printed on yellow paper to help highlight the fact that there are two designs during the transition period. , Ref: Letter J. P.

A 1% A.Q.L. was selected but may be revised in the future if ovality complaints persist. Ref: Letter A/C Sewer Pipe, Process Capability re "Min Wall Thickness Thru O.D.i From L.C. Kurfuerst dated 11-15-78. 3) Dimensions for Class 6000 and 7000 pipe, couplings and fittings have been added per Marketing's request in the 18" thru 24" sizes. These have been covered by several NSPS's in the past and are now standard products. 4) An alternate method for making small diameter Tees and Wyes has been shown. This method has been covered by NSPS for several years and uses pipe stock for the main rather than coupling stock. This method is applicable for the west coast plants only. 5) The B.O.D. tolerance for pipe and fittings have been changed. Gen erally pipe and some fittings were given minimum requirements only because excessive BOD will not affect their function. Couplings and most of the other fittings were given a +.25" -.00" tolerance because excessive B.O.D.'s can interfere with wye and tee clearances. The Formulations and Yields are going to be revised but will still be based on +.04" over the minimum B.O.D. The intent is that costs will control the B.O.D.'s. 6) B.O.D. tolerances have been added to the Manhole Stubs. This was important due to precast manholes and special adaptor rings which are available and cannot seal on excessively thick or declassed pipe. 7. PVC Manhole adaptors for 18" thru 27" PVC pipe were added. Ref: Letter J.P. Ungerman to M.R. Streepy dated 2-2-79 "Assignment #108-78 A/C Manhole Adaptors for 18" - 27" PSM PVC Pipe. 8. 12" Small Diameter Sewer FM's were removed. CTD015290 9.
