Product Code:SAE AMS2667
Title:Brazing, Silver, For Small Pressurized Fittings
Issuing Committee:Ams B Finishes Processes And Fluids Committee
Scope:This specification covers the engineering requirements for producing brazed joints in parts fabricated from austenitic corrosion and heat resistant steels, but may also be used on carbon or low-alloy steels or copper alloys, and the properties of such joints.Product Code:SAE AS1194
Title:Regulator Oxygen Diluter Demand, Automatic Pressure Breathing (Cancelled Oct 1997)
Issuing Committee:A-10 Aircraft Oxygen Equipment Committee
Scope: To define optimum standards of design, construction and performance for Diluter Demand, Automatic Pressure Breathing, Oxygen Regulators. AS 861, 'Minimum General Standards for Oxygen Systems,' is applicable as supplemented by this specification. This document supersedes in part AS 463, 12-15-56, which is cancelled. This specification covers two types of Diluter Demand, Automatic Pressure Breathing, Oxygen Regulators for use in civil type aircraft. The intent is that the regulators be of two configurations, operable at inlet pressures of 40 to 90 psig and 50 to 150 psig.
