AN821 (REV. 8) (NOTICE 2), AIR FORCE-NAVY AERONAUTICAL STANDARD: ELBOW FLARED TUBE, 90 DEG. (15-NOV-2010) [S/S BY SAE-AS1034]

AN821 (REV. 8) (NOTICE 2), AIR FORCE-NAVY AERONAUTICAL STANDARD: ELBOW FLARED TUBE, 90 DEG. (15-NOV-2010) [S/S BY SAE-AS1034]., AN821 Rev 8, dated 5 August 1983, is hereby cancelled. Future acquisitions for this item should refer to SAE-AS1034, "Fitting, Elbow, 90 DEG, Standard and Reducer, Flared". (Copies of these documents are available from SAE International, 400 Commonwealth Drive, Warrendale, PA 15096-0001, Tel: 877-606-7323 (inside USA and Canada) or 724-776-4970 (outside USA), www.sae.org.) Reason for NOTICE 2: SAE inactivated Part or Identifying Number (PIN) with material code letter D for replacement parts and for new design to use code letter W. This is because code letter W is stronger in tensile strength than code letter D. This is based on the previous PA’s revision, as a result of lessons learned. Plus to add back material code letter S for replacement parts and for new design to use code letter R. The code letter R is better for applications requiring higher temperature. Also added size 28. Table l provides a detailed cross-reference of cancelled AN821 Rev 8 PINs and replacement SAE-AS1034 PINs. CAUTION: The supersession information is valid as of the date of this notice and may be superseded by subsequent revisions of the superseding document.
