BS 60832-1:2010 pdf download – Live working — Insulating sticks and attachable devices Part 1 : Insulating sticks
The marking shall be durable, clearly visible and legible to a person with normal or correctedvision without additional magnification.The marking shall be placed in a position remote fromthe strip indicating the positions of internal metal parts.
Other characteristics or information not needed at the work location,like the year ofpublication of the standard,shall be associated to the product item by other means,such ascoded information(bar codes, microchips, etc.), or shall be associated to its packaging.
No marking shall adversely affect performance of insulating parts. Where a removablemarking (e.g. a stick-on label) is used, the electrical performance of the tool shall remainunaffected when the marking is removed.
4.8Instructions for use
Each tool shall be supplied with the manufacturer’s written instructions for use and care,
These instructions shall be prepared in accordance with the general provisions given inIEC 61477.
These instructions shall include, as a minimum,recommendations for maximum mechanicalload (see 4.4.2), cleaning,storage and transportation,periodic testing,possible repair anddisposal of the tool.
The present standard provides testing provisions to demonstrate compliance of the product tothe requirements of Clause 4.These testing provisions are primarily intended to be used astype tests for validation of the design input.Where relevant,alternative means (calculation,examination, tests,etc.), are specified within the test subclauses for the purpose of insulatingsticks having completed the production phase.
To show compliance with this standard,the manufacturer shall prove that the type testsreferred to in Tables B.1 and B.2 have been successfully carried out on at least three tools ofeach type of assembly.
However,when differences between various types of tools are limited in number,tests thatare unaffected by the differing characteristics of the tools can be carried out on a single typeof tool and the results can be used for the other tool types.
Tensile force tests need not be repeated when tool types only differ in the length of theinsulating foam-filled tube or solid rod.
The tests referred to in Tables B.1 and B.2 shall be performed in the specified numberedorder.
The required values of mechanical forces specified in Clause 5 shall be reached using a rateof increase between 1 % and 10 % of the rated force per second. The forces shall be appliedwith an accuracy of 士5 %.
NOTE For example, if the rated tensile force stated by the manufacturer for a given tool is FTN = 100 N, the rateof increase will be between 1 N/s and 10 N/s and the applied force to the tool wili be between a5 N and 105 N.
The dimensions specified in mm in Clause 5 shall be verified with an accuracy of +2 %.Unless otherwise specified, room temperature shall be (25± 10)°c.
When visual inspection is specified, it shall be understood to be visual inspection by a person with normal or corrected vision without additional magnification.
5.2 Visual inspection
Each tool shall be visually inspected to detect manufacturing defaults and to check proper functioning and compliance with requirements included in 4.2, 4.5, 4.6, 4.7 and 4.8 where applicable.
5.3 Dimensional check
Each tool shall be measured to ensure that its dimensions match the manufacturer’s rated dimensions.
5.4 Durability of marking
The durability of the marking shall be verified by thoroughly cleaning the marking for at least 1 min with a piece of lint-free cloth dampened with water and then rubbing it vigorously for a further minimum of 1 min with a piece of lint-free cloth dampened with isopropanol (CH 3 -CH(OH)-CH 3 ).
NOTE 1 It is the employer’s duty to ensure that any relevant legislation and any specific safety instructions regarding the use of isopropanol are fully observed.
The test shall be considered as passed if the marking remains legible and the letters do not smear.
The surface of the tool may change. No signs of loosening shall be present for labels.
NOTE 2 Marking made by moulding or engraving need not be subjected to this test.
