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 1.2.1.1 Line guards,

1.2.1.2 Line guard connectors,

1.2.1.3 Insulator covers, and

1.2.1.4 Deadend covers.

1.2.2 Structure and Apparatus Covers:1.2.2.1 Pole guards,

1.2.2.2 Ridge pin covers,

1.2.2.3 Switch blade covers,

1.2.2.4 Arm guards,

1.2.2.5 Cutout covers, and

1.2.2.6 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.
