(R) Automotive and Off-Highway Air Brake Reservoir Performance and Identification Requirements

1.

Scope—This SAE Standard applies to all new production air brakereservoirs used in automotive vehicles and off-road machines. This document defines an “air brake reservoir” as a reservoir having single or multiple compartments that is used for storage of compressed air. This document does not apply to accumulators or reservoirs for storage of gases other than compressed air. The reservoirs tested per these requirements shall be selected from production stock andshall be equipped with all permanently attached items such as mounting brackets and fitting bosses.

1.1

Purpose—The purpose of this document is to provide MINIMUM performance requirements and a method of identifying new production air brake reservoirs. Additional requirements for corrosion resistance and pressure fatigue tests should be considered by the vehicle manufacturer. Additional ordifferent considerations should be given to non-metallic and non-circular reservoirs. References Applicable Publications—The following publications form a part of this specification to the extent specified herein. Unless otherwise indicated, the latest version of SAE publications shall apply. ASTM PUBLICATIONS—Available from ASTM, 100 Barr Harbor Drive, West Conshohocken, PA 19428-2959.

Certification requirements Proof Tests—All air brake pressure reservoirs shall be capable of withstanding a hydrostatically applied internal pressure of not less than five times the reservoir rated working pressure. There shall be noindication of rupture or permanent circumferential deformation exceeding 1% after having been subjected to this test pressure for 5 min. When testing multiple compartment reservoirs, the pressure shall be applied to and exhausted from all compartments simultaneously. Then pressurize each compartment individually to 1.5 times the indicated rated working pressure to verify the baffle strength in bothdirections.

SAE J10 Revised FEB2000 3.2 FMVSS Conformance (Off-Highway Applications neednot comply)—Initially and at a continuing frequency of not less than once annually, one or more air brake reservoirs of each size, type (single compartment, multiple compartment, dual compartment with integral check valve) and mounting configuration must be tested for compliance to all requirements of applicable Federal Motor Vehicle Safety Standards. Performance Requirements Leakage Tests—Each airbrake reservoir shall be capable of the following applicable tests. When air pressure is used to perform this test, protection against explosive rupture shall be provided. The effectiveness of the protective enclosure shall be verified prior to use. A sealing compound may be used to seal port threads. SINGLE COMPARTMENT RESERVOIRS—All air reservoirs shall be subjected to twice the indicated...
