This standard establishes a test method to determine the susceptibility of an electrical connector or socket system to the potential degradation mechanism of a dust/fiber environment common to an office or manufacturing area. This method may be used as a preconditioning test whereby the test specimen is exposed to a heavy concentration of dust and then exposed to a subsequent environment or as a ??stand alone?? test. This test should not be considered as an alternate or replacement for the EIA-364-50 (Sand and Dust Test Procedure for Electrical Connectors and Sockets) that simulates an outdoor desert type environment. CAUTION - This procedure may involve hazardous materials@ operations and equipment. This procedure does not purport to address all safety problems associated with its use or all regulatory requirements. It is the responsibility of the user of this procedure to establish appropriate safety and health practices and to determine the applicability of regulatory limitations before its use.
