5、 to reflect the new SAE Technical Standards Board format. Definitionshave been changed to Section 3. All other section numbers have changed.1. ScopeThis SAE Recommended Practice describes the requirements necessary for four-way subbasemounted, directional air-control valves to be used in automotive
6、manufacturing applications. It includesminimum performance, operation, and physical requirements to qualify the valves for service in automotivemanufacturing applications. Included are spool, poppet, and sliding disc types of air valves for pressures in arange of vacuum to 1034 kPa (150 lb/in2) gage
7、, and temperatures from 18 to 60 C (0 to 140 F).1.1 RationaleThis revision of SAE J2051 incorporates changes to the contaminant, the original of which wasfound to cause coagulation in the components tested. The revised contaminant is a mixture of 75% iron filingsand 25% ferric(ous) oxide; whereas th
8、e previous contaminant was 100% ferric(ous) oxide. In addition, theamount of water injected is increased; and a prescribed schedule of injecting these contaminants is provided.2.
