Standard Requirements for Aerospace Sealants and Adhesion Promoters

2022-11-14
CURRENT
AS5502E
This SAE Aerospace Standard (AS) establishes standard requirements for aerospace sealants and adhesion promoters, which may be incorporated as part of SAE Aerospace Material Specifications (AMS) for such products. This document provides for commonality of methods and procedures for responsibility for inspection, source inspection, classification of tests, establishment of/and qualification to qualified products lists, approval, reports, resampling and retesting, packaging, and marking.
Standard

Sealing Compound, Polythioether Rubber, Light-Cured, for Integral Fuel Tanks and General Purpose, Intermittent use to 360 °F (182 °C)

2022-04-25
CURRENT
AMS1389
This specification covers polythioether rubber fuel resistant sealing compounds, supplied as a two-component system, which cure rapidly when exposed to a cure on demand (CoD) light source used to initiate a reaction that generates crosslinking of sealant polymers. Type 2 compounds also cure at ambient conditions, without light exposure.

Insulating Compound, Electrical, Embedding, Reversion Resistant Silicone

2021-03-05
CURRENT
AS81550B
This specification covers the requirements for two types of a two-part, transparent, reversion resistant flexible insulating compound, to provide resilient, environmental, and electrical insulation of components in systems in temperature range -85 to 392 °F (-65 to 200 °C). These insulating compounds are intended for embedding, potting or encapsulation of electrical and electronic components in systems where tear resistance is not critical, but their use is not limited to such applications. These transparent compounds allow visual circuit and part identification and facilitate part replacement and repairs. The insulating compound shall cure in sections of unlimited thickness, either exposed to air or completely sealed.

Standard Contaminant for Testing Aerospace Cleaners

2020-07-14
CURRENT
AMS7201
This specification establishes requirements for a standard contaminant that can be used to represent typical soils encountered in aerospace cleaning. This standard contaminant consists of materials that are common contaminants found in aircraft maintenance depots and manufacturing facilities.

HISTORICAL
AS5127/2C
This SAE Aerospace Standard (AS) describes the test methods to determine the flammability performance and capability to control the passage of, and effects from, fire on aircraft firewall sealing compounds. The methods are based requirements of FAR Part 25 Sections 25.865, 25.867, 25.1191, and 25.1193 and may be used to demonstrate compliance with the requirements established by FAA AC 20-135. This standard shall be used in conjunction with applicable material specifications.
