test

Standards Subcommittees of ASC C119• C119.7 Subcommittee on High Operating

Temperature Connector Systems (Above 93oC) – A New C119.7-XXXX Standard is being developed– Phase 1 of a Joint ANSI C119.7 - EPRI Project for testing

the proposed high temperature test protocol is in progress

– Testing of ACSS, ACCR, and ACCC conductor–connector systems to validate the proposed test protocol is approximately 50% complete

– Phase 1 of the C119.7 – EPRI test protocol evaluation is scheduled to be completed in 2011

– EPRI is doing additional long duration (1,500 cycle) heat cycle performance testing and scientific evaluation of connector – conductor interface performance at high temperatures

– Phase 2 of the C119.7 – EPRI test protocol evaluation is being planned for 2012

Standards Subcommittees of ASC C119

• C119 Testing Methods and Directives Subcommittee

– This Subcommittee has the responsibility of evaluating and recommending improvements for test lab procedures that are common to all of the C119 Standards

– The Subcommittee continues to develop a Common Test Requirements Guide Document which will be published as a supplement as applicable to all the C119 Standards
