IEC 62193-2003 pdf – Live working – Telescopic sticks and telescopic measuring sticks.
1 Scope This International Standard covers telescopic sticks and telescopic measuring sticks to be used for live working on a.c. or d.c. electrical installations at 1 000 V and above for a.c. and 1 500 V and above for d.c. The telescopic sticks are designed to accept attachments that meet appropriate live working standards and, together with these attachments, may be used to perform mechanical work on live parts at a distance. Telescopic sticks are also designed to accept diagnostic devices that meet appropriate live working standards and are used to make the diagnostic devices reach parts of an installation to be tested. Telescopic measuring sticks, or tele- scopic sticks equipped with graduations, are used to measure distances to or between live parts. NOTE Under certain circumstances, the telescopic sticks covered by this standard can be used for installing portable earthing or earthing and short-circuiting equipment if the mechanical stresses during use are lower than the rated values. The tools (telescopic sticks and telescopic measuring sticks) covered by this standard are for use under dry conditions but could also be used under very humid conditions, using appropriate working procedures. Telescopic hook sticks are not covered by this standard. Telescopic bonding sticks and any other speciality telescopic sticks designed at the request of users are not covered by this standard. 2 Normative references The following referenced documents are indispensable for the application of this document.

NOTE 2 For use in Sweden, the filled or solid section(s) may be replaced by section(s) of sealed hollow tubes. [Definition 3.1.14 of IEC 60743, modified] 3.2 telescopic measuring stick hand stick made of retractable insulating tubes including at least one filled or solid section. This tool is used to determine conductor-to-ground and conductor-to-conductor distances and other clearances and not intended to be used under tension/compression and/or torque NOTE For use in Sweden, the filled or solid section(s) may be replaced by section(s) of sealed hollow tubes. [Definition 3.1.15 of IEC 60743, modified] 3.3 bonding stick hand stick used to apply bonding leads 3.4 tip section working end of the tool, filled or solid, which provides the primary insulating characteristics when fully extended. It is the part of the tool which comes in contact or in close proximity with the live part NOTE For use in Sweden, the filled or solid-tip section may be replaced by a section of sealed hollow tube. 3.5 hydrophobic lacking affinity for water (water repellence). An hydrophobic material prevents water droplets spreading on its surface 3.6 lock assembly device or mechanism that locks the telescopic sections in the working position
3.7 reinforced tube tube which is especially designed to resist mechanical strain [Definition 3.3.1 of IEC 61235, modified] 3.8 standard tube tube which may be submitted occasionally to mechanical loading and should be able to self- restore by the nature of the material itself [Definition 3.3.2 of IEC 61235] 3.9 light tube tube which has not been designed and manufactured to resist mechanical stresses except its own weight [Definition 3.3.3 of IEC 61235] 3.10 type test test performed on one or more items representative of the production, made to show that the product meets certain specifications [Definition 3.10 of IEC 61318 and IEV 151-16-16, modified] 3.11 routine test test performed on each item during or after manufacture to ascertain whether it complies with certain criteria [Definition 3.11 of IEC 61318 and IEV 151-16-17, modified] 3.12 sampling test test on a sample [Definition 3.12 of IEC 61318 and IEV 151-16-20] 3.13 acceptance test contractual test to prove to the customer that the item(s) meet(s) certain conditions of its specification [Definition 3.13 of IEC 61318 and IEV 151-16-23, modified]
