BS EN 60660:2000

This standard BS EN 60660:2000 Insulators. Tests on indoor post insulators of organic material for systems with nominal voltages greater than 1 kV up to but not including 300 kV is classified in these ICS categories:

• 29.080.10 Insulators

Applicable to post insulators of organic material for indoor service in electrical installations or equipment operating in air at atmospheric pressure on alternating current with a nominal voltage greater than 1 000 V up, but not including, 300 kV, as defined by range I of IEC 60071-1, and a frequency not greater than 100 Hz. Composite insulators are not covered by this standard.
To define the electrical and mechanical characteristics and to prescribe methods of testing and acceptance criteria.
