Product Code:SAE AIR1564
Title:Cross Reference for Materials for Fluid Systems Components Including Military and Federal Specifications and Their International Equivalents
Issuing Committee:G-3, Aerospace Couplings, Fittings, Hose, Tubing Assemblies
Scope:This SAE Aerospace Report (AIR) provides a cross reference for SAE material standards to other similar standards. The SAE Committee G-3 invites comments and recommendations for the addition of materials and information for inclusion into this informational report.No attempt has been made to obtain samples of the materials or conduct physical and chemical analyses to determine if they are equivalent. Anyone using this AIR, therefore, is cautioned to verify for themselves the interchangeabillity of the specific materials.Additional contributions of missing or supplemental data should be directed to SAE marked for the attention of Committee G-3.
