Foreword

The text of the International Standard IEC 855:1985, prepared by IEC TC 78, Tools for liveworking, was approved by CENELEC as HD 496 S1 on 1987-12-02.

This Harmonization Document, together with common modifications prepared by theTechnical Committee CENELEC TC 78, was submitted to the formal vote and was approvedby CENELEC as EN 60855 on 1996-03-05.

The following dates were fixed:

- latest date by which the EN has to be implementedat national level by publication of an identicalnational standard or by endorsement (dop) 1997-03-01

- latest date by which national standardsconflicting with the EN have to be withdrawn (dow) 1997-03-01

For products which have complied with HD 496 S1 S1:1988 before 1997-03-01, as shownby the manufacturer or by a certification body, this previous standard may continue to applyfor production until 2002-03-01.

INSULATING FOAM-FILLED TUBES AND SOLID RODSFOR LIVE WORKING

INTRODUCTIONA specification of tests to verify the electrical and mechanical performance of insulating tubes and rods

is dependent in part on their construction. This standard covers foam-filled tubes and solid rods such asthose currently available without excluding possible future developments of tubes protected internally inother ways and tubes and solid rods protected externally. Any proposed equipment of different designmay call for re-examination of the tests, so that they may be adapted to the construction proposed.

This standard is applicable to insulating foam-filled tubes and solid rods made of syntheticmaterials and intended for tools and equipment for live work on systems operating at voltagesabove 1 kV.

Separate special technical standards give details of tests for fittings and attachments to thesepoles and rods, adaptable tools and complete tools.
