IEEE/AIEE 504-1958

The properties determined by these tests are inherent in the brush materials themselves as distinguished from performance characteristics in operation on electric equipment

It is the purpose of this Code to provide a uniform (standard) procedure for measuring the properties of materials, properties of shunt connections, and operating characteristics, for carbon, carbon-graphite, electrographitic, graphite, and metal-graphite brushes
