Title:Test Method for Aerospace Firewall Sealant Flame Penetration
Issuing Committee:Ams G9 Aerospace Sealing Committee
Scope: This SAE Aerospace Standard (AS) describes the procedures for the flammability testing of aircraft firewall sealants in accordance with the requirements of FAR Part 25 Sections 25.865, 25.867, 25.1191, and 25.1193. This test method is intended to determine the capability of sealant materials to control the passage of and effects from fire.This test is used to demonstrate compliance with the requirements established by FAA regulations for flammability characteristics of aircraft firewall sealant materials as part of the Type Certification requirements.

This test method is intended to determine the capability of sealant materials to control the passage of and effects from fire.This test is used to demonstrate compliance with the requirements established by FAA regulations for flammability characteristics of aircraft firewall sealant materials as part of the Type Certification requirements.Product Code:SAE AS7474
Title:Bolts and Screws, Steel Corrosion Resistant, UNS S17400 Tensile Strength 140 ksi Procurement Specification
Issuing Committee:E-25 General Standards For Aerospace And Propulsion Systems
Scope: This specification covers bolts and screws made from a corrosion and heat resistant, martensitic iron base alloy of the type identified under the Unified Numbering System as UNS S17400. The following specification designations and their properties are covered: AS7474 140 ksi minimum ultimate tensile strength at room temperature 100 ksi stress corrosion test 72 ksi to 7.2 ksi tension-tension fatigue; AS7474-1 140 ksi minimum ultimate tensile strength at room temperature 100 ksi stress corrosion test 88 ksi minimum ultimate shear strength at room temperature. Primarily for aerospace propulsion system applications where corrosion resistance and high strength in tension is required in temperatures not to exceed 600掳 F.
