EUROLAB, with its state-of-the-art accredited laboratories and expert team, provides precise and fast testing services within the scope of SAE J1131 testing. The purpose of this SAE Standard is to establish uniform methods for testing SAE J844 piping and fittings used in automotive air brake systems.
This standard also specifies minimum qualifications for tensile and compressive capacities, vibration resistance under cyclic temperatures, serviceability and joint compatibility requirements. Specific tests and performance criteria applicable to the hose are specified in SAE J844.
The standard is applicable to assemblies made from SAE J844 type A and B nylon tubing and SAE J246 type coupling components.
SAE J844 type A and B nylon tubing are plastic materials commonly used in automotive air brake systems. Type A tubing is made of a single-layer nylon material, while type B tubing is made of a multi-layer structure that includes an outer nylon layer, a middle adhesive layer, and an inner nylon layer. The multi-layer construction of type B hose provides greater resistance to abrasion, kinking and bursting.
SAE J246 type fittings are specifically designed for use with non-metallic piping and are used to connect piping to other components within the air brake system. These fittings are made of brass or steel and are available in a variety of configurations, including compression, barbed, and bass-connect designs.
The requirements set out in SAE J1131 cover several important aspects of non-metallic tubing and fittings used in automotive air brake systems:
Compliance with SAE J1131 is important to ensure the safety and reliability of non-metallic tubing and fittings used in automotive air brake systems. By adhering to these standards, manufacturers can ensure that their products meet the highest levels of quality and performance.
