Product Code:SAE ARP4784
Title:Definitions and Limits, Metal Material Defects and Surface and Edge Features, Fluid Couplings, Fittings and Hose Ends
Issuing Committee:G-3, Aerospace Couplings, Fittings, Hose, Tubing Assemblies
Scope: This SAE Aerospace Recommended (ARP) provides the requirements for surface defects, performance and evaluation criteria for various defects and discontinuities encountered in aerospace couplings, tube fittings and hose assembly components. The discontinuities fall into three basic categories: inherent discontinuities, which are present in the raw material stock; primary processing discontinuities, which are caused by processes which work the metal down by either hot or cold deformation into semifinished products; and secondary processing discontinuities, which are associated with finishing operations which occur after rolling. This document is intended to be used in conjunction with existing callouts on government and industry standards. Recommendations of allowable discontinuities are only guidelines, and any government/industry requirements will prevail over this document.【英文标准名称】:Particleboards;specifications-Part5:Requirementsforload-bearingboardsforuseinhumidconditions;GermanversionEN312-5:1997
