ASTM D622-99

ASTM D622-99

 

ASTM D622 provides ASTM test methods that are suitable for testing conventional hose types used for operating air brake and vacuum brake systems, whether they are used on a single motor vehicle, or when used for a combination of motor vehicles as connecting or transmission lines. It is widely used across automotive, commercial vehicle, and rubber product manufacturing industries to verify brake hose integrity under operational conditions. Presto Stantest's precision rubber testing instruments support manufacturers in conducting ASTM D622 compliance evaluations under controlled laboratory conditions. 

Significance

The purpose of these test methods is 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 hose performance and safety. By establishing standardized testing procedures, ASTM D622 enables manufacturers to consistently validate brake hose quality, identify material weaknesses, and ensure products meet defined durability and performance thresholds before being installed in vehicle braking systems where failure could have serious safety consequences.

Scope

The types of hose covered by these test methods include hose that can be assembled with suitable metal couplings; the term 'rubber,' as used in these test methods, includes synthetic compounds as well as natural rubber compounds. The standard applies to brake hose manufacturers, automotive component suppliers, quality inspection bodies, and procurement agencies requiring standardized evaluation procedures for air and vacuum brake hose production, incoming material verification, and regulatory compliance across automotive and commercial vehicle manufacturing sectors.
