Historical (view previous versions of standard)
Significance and Use
The purpose of these test methods are to provide nationally recognized test methods for air brake and vacuum brake hose, in particular the hose specifications SAE J1402 and SAE J1403, and to provide producers, distributors, and users with a basis for evaluating the characteristics of these hose products.
1.1 These test methods are intended for use in testing the conventional types of hose employed for the operation of air brake and vacuum brake systems, either on a single motor vehicle or as connecting or transmission lines in a combination of vehicles. The hose may be assembled with suitable metal couplings or may be as fabricated for use with detachable fittings. The term “rubber” as used in these test methods includes synthetic compounds as well as compounds of natural rubber.
1.2 The values stated in SI units are to be regarded as the standard. The values given in parentheses are for information only.
1.3 This standard does not purport to address all of the safety problems, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
