4.3 Mechanical protection When necessary, the ends of each device shall have adequate means for mechanical protection, such as an end-cap. Metal devices shall be carefully designed to ensure that all edges are rounded where this does not impair the function of the device. 4.4 Protection against corrosion Metal parts shall be protected against corrosion either by their composition or by the use of a suitable surface treatment. 4.5 Marking Each device shall be marked with the following permanent items of marking:
− manufacturer’s name or trademark;
− type reference;
− year and (if possible) month of manufacture;
− symbol IEC 6041 7-521 6 (2002-1 0)
– Suitable for live working; double triangle (see Annex B);
NOTE The exact ratio of the height of the figure to the base of the triangle is 1 ,43. For the purpose of convenience, this ratio can be between the values of 1 ,4 and 1 ,5.
− number of the relevant IEC standard immediately adjacent to the symbol (IEC 60832-2). The marking shall be durable, clearly visible and legible to a person with normal or corrected vision without additional magnification. Other characteristics or information not needed at the work location, like the year of publication of the standard, shall be associated to the product item by other means, such as coded information (bar codes, microchips, etc.), or shall be associated to its packaging.
4.6 Instructions for use Each device 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 in IEC 61 477. These instructions shall include as a minimum, recommendations for maximum mechanical load (see 4.2.2), cleaning, storage and transportation, periodic testing, possible repair and disposal of the device.
5 Tests
5.1 General
The present standard provides testing provisions to demonstrate compliance of the product to the requirements of Clause 4. These testing provisions are primarily intended to be used as type 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 devices having completed the production phase. To show compliance with this part of the standard, the manufacturer shall prove that the type tests referred to in Tables C.1 and C.2 have been successfully carried out on at least three devices of each type. However, when differences between various types of devices are limited in number, tests that are unaffected by the differing characteristics of the device can be carried out on a single type of device and the results can be used for the other types of device.
The tests referred to in Tables C.1 and C.2 shall be performed in the specified numbered order. The required values of mechanical forces specified in Clause 5 shall be reached using a rate of increase between 1 % and 1 0 % of the rated force per second. The forces shall be applied with an accuracy of ±5 %.
NOTE For example, if the rated tensile force stated by the manufacturer for a given tool is F
TN = 1 00 N, the rate
of increase will be between 1 N/s and 1 0 N/s and the applied force to the device will be between 95 N and 1 05 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 ± 1 0) °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 device shall be visually inspected to detect manufacturing defaults and to check proper functioning and compliance with requirements included in 4.3, 4.4 and 4.5 where applicable.
5.3 Dimensional check Each device shall be measured to ensure that its dimensions match the manufacturer’s rated dimensions.
5.4 Compatibility check It shall be verified by attaching each attachment system that each type fits properly and securely on the stick for which it has been designed for.
5.5 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.
