Over deze norm
1.1 This specification covers the requirements, sizes, construction, tests, and procedures for unused ropes for use by electrical utilities and related industries on energized lines operating at voltages higher than 1 kV.
1.2 This specification covers the minimum electrical, mechanical, and physical properties guaranteed by the manufacturer and the detailed procedures by which such properties are to be determined. The purchaser has the option to perform or have performed any of these tests in order to verify the guarantee. Claims for failure to meet the specification are subject to verification by the manufacturer.
1.3 The rope to which this specification applies is designed to be used in a clean and dry condition, on or near energized lines.
1.4 A margin of safety shall be allowed between the maximum voltage and working distances on which it is used and the test voltage and lengths at which it is tested.
1.5 It is common practice for the user of this type of equipment to prepare complete instructions and regulations to govern in detail the correct and safe use of such equipment.
1.6 The use and maintenance of this equipment is beyond the scope of this specification.
1.7 The values stated in SI units are to be regarded as the standard.
1.8 The following safety hazards caveat pertains only to the test method portion, Section 11, of this specification: 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. The test levels used in this standard are for testing under laboratory conditions and are not to be regarded as safe use levels.
