|Publication Date:||1 January 2000|
1.1 These test methods cover three electrical tests on plastic guards and assembled guard systems. They are:
1.1.1 Method A--Withstand voltage proof test,
1.1.2 Method B--Flashover voltage, and
1.1.3 Method C--Leakage current.
1.2 These methods cover, but are not limited to, the following typical guards:
1.2.1 220.127.116.11 Line guards,
18.104.22.168 Line guard connectors,
22.214.171.124 Insulator covers, and
126.96.36.199 Deadend covers.
1.2.2 Structure and Apparatus Covers:188.8.131.52 Pole guards,
184.108.40.206 Ridge pin covers,
220.127.116.11 Switch blade covers,
18.104.22.168 Arm guards,
22.214.171.124 Cutout covers, and
126.96.36.199 Structural barriers,
1.3 It is common practice for the user of this equipment to prepare instructions for the correct use and maintenance.
1.4 The use and maintenance of this equipment is beyond the scope of these test methods.
1.5 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
