CLC/TC 78 - Equipment and tools for live working

This document is applicable to portable ladders made only of non-conductive stiles, including accessories (pole leaning device, adjustable levelling device, adjustable ladder stabilizer, etc.) used to work on or near electrical systems and installations in the low voltage range (up to 1 000 V AC/1 500 V DC). These ladders are used to provide temporary access, generally on overhead line structures, and to undertake electrical operations. They are expected to be used by one person only. These ladders, in conjunction with other protective equipment provide sufficient insulation level to protect against inadvertent contact with live low voltage installations. This document does not cover ladders used for live working on electrical installations at voltages above 1 000 V AC and above 1 500 V DC. These insulating ladders are separately covered by EN 61478. This document does not cover products not made entirely with non-conductive stiles generally called mixed ladders. In this case the EN 131 series apply. This document does not cover step stools, which are covered by EN 14183. These ladders are only for specific professional use. Only skilled persons, after an appropriate training, can use this type of ladder for professional applications. The products designed and manufactured according to this document contribute to the safety of the users provided they are used by skilled persons, in accordance with safe methods of work and the manufacturer instructions for use (where appropriate). Annex E gives a rationale to explain how a ladder which fulfils the requirements of this document used with correct accessories gives better safety for the user than an ordinary ladder.

This standard is applicable to electrically insulating helmets used for working live or close to live parts on installations not exceeding 1 000 V AC or 1 500 V DC. These helmets, when used in conjunction with other electrically insulating protective equipment prevent dangerous current from passing through persons via their head.

This document is applicable to eye, face and head protectors used in work where there is a risk of exposure to an electric arc hazard. Such protectors consist of one or several devices (e.g. hood, goggles, balaclavas, face shields, helmets, etc.), which might need to be combined together in order to give protection to eye, face and head for the intended use. This document covers the performance requirements for protectors and single protective devices considering thermal, optical and mechanical hazards of an electric arc. Because of the limitations of test apparatus at very high energy arcs, no arc rating above 4 100 kJ/m2 (100 cal/cm2) can be assigned to protectors. This document does not cover protection against electric shock, noise, the consequences of physical and mental shock and the toxic influences caused by an electric arc. This document does not cover protectors for work intentionally using an electric arc, e.g. arc welding, plasma torch. This document does not cover face-screens for the reduction of an electric field inside conductive clothing in accordance with IEC 60895. Any other claims of the manufacturer for protection against other hazards to eye or face (e.g. welding radiation, hazards occurring during fire-fighting) are outside the scope of the document. Products designed and manufactured in accordance with this document contribute to the safety of the users provided they are used by skilled persons, in accordance with safe methods of work and the instructions for use.

This standard shall be read with EN 50186-1 "Operation of electrical installations - Part 1: General requirements" and contains national annexes which need to be used on this subject.

IEC 61482-1-1:2019 specifies test method procedures to determine the arc rating of flame resistant clothing materials and garments or assemblies of garments intended for use in clothing for workers if there is an electric arc hazard. An open arc under controlled laboratory conditions is used to determine the values of ELIM, ATPV or EBT of materials, garments or assemblies of garments. NOTE 1 The user can, if he desires, classify the arc protective performance into arc rating protection levels based on ELIM, ATPV and/or EBT values which correspond best to the different hazard and risks levels that can result from the user’s risk analysis. NOTE 2 This document is not dedicated to classifying the arc protective performance of the material and clothing into arc protection classes. Procedures determining these arc protection classes APC1 and APC2 are specified in IEC 61482 1-2, which uses a constrained arc for testing.  NOTE 3 This test method is not intended and not appropriate to evaluate whether materials or garments are flame resistant or not, as this is covered in IEC 61482-2. Other effects than the thermal effects of an electric arc like noise, light emissions, pressure rise, hot oil, electric shock, the consequences of physical and mental shock or toxic influences are not covered by this document. Protective clothing for work intentionally using an electric arc, e.g. arc welding, plasma torch, is not covered by this document. This second edition cancels and replaces the first edition published in 2009. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition: - addition of the Incident energy limit (ELIM) as a further arc rating performance property value; - replacement of char length requirement in the scope by indication that Procedure A is applicable for testing of materials meeting the limited flame spread requirements of IEC 61482-2; - clarification of the definition and the meaning of the Stoll curve; - modification of specification of positioning of monitor sensors with respect to the electric arc as function of intended high incident energy exposure of test specimens; - modification of specifications of monitor sensor construction; - specification of black paint; - elimination of calorimeters from the chest of the mannequin; - specification for possible positioning of mannequin(s) at a height different from the centre of the electric arc and possible turning in order to adequately expose all parts of the garment or clothing which would affect performance; - more explicit description of requirements for data acquisition system; - preconditioning of the samples; - modification of requirements for apparatus and arc exposure verification by bare shots; - more explicit description of test procedures A and B, in particular the subclauses dealing with “sequence of test”, “test parameter” and “test criteria”; - addition of determination of arc rating values of garments and/or garmet assemblies. Key words: Protective Clothing, Thermal Hazards, Open Arc, Arc Rating

The products designed and manufactured according to this document contribute to the safety of the users provided they are used by skilled persons, in accordance with safe methods of work and the instructions for use (where appropriate). This document has been prepared in accordance with the requirements of IEC 61477 where applicable. The products covered by this document may have an impact on the environment during some or all stages of its life cycle. These impacts can range from slight to significant, be of short term or long-term duration, and occur at the global, regional or local level. This document does not include requirements and test provisions for the manufacturers of the products, or recommendations to the users of the products for environmental improvement. This fourth edition cancels and replaces the third edition, published in 2012. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition: a) addition of a third category of tools has been added, namely hybrid hand tools; b) introduction of a new informative Annex A on examples of insulated, insulating and hybrid hand tools. Key words: Live Working, Insulated, Insulating, Hand Tools

IEC 61243-1:2021 is applicable to portable voltage detectors, with or without built-in power sources, to be used on electrical systems for voltages of 1 kV to 800 kV AC, and frequencies of 50 Hz and/or 60 Hz. This document applies only to voltage detectors of capacitive type used in contact with the bare part to be tested, as a complete device including its insulating element or as a separate device, adaptable to an insulating stick which, as a separate tool, is not covered by this document (see 4.4.2.1 for general design). Other types of voltage detectors are not covered by this document. Self ranging voltage detectors (formally "multi range voltage detectors") are not covered by this document. Some restrictions or formal interdictions on their use are applicable in case of switchgear of IEC 62271 series design, due to insulation coordination, on overhead line systems of electrified railways (see Annex B) and systems without neutral reference. For systems without neutral reference, the insulating level is adapted to the maximum possible voltage to the earth (ground). Products designed and manufactured according to this document contribute to the safety of users provided they are used by persons trained for the work, in accordance with the hot stick working method and the instructions for use. Except where otherwise specified, all the voltages defined in this document refer to values of phase-to-phase voltages of three-phase systems. In other systems, the applicable phase-to-phase or phase-to-earth (ground) voltages are used to determine the operating voltage. This third edition cancels and replaces the second edition published in 2003 and Amend-ment 1:2009. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition: a) The scope is more precise, stating that only bare contact to the part to be tested is reliable for these contact voltage detectors. The rationale is that tests on painted or coated conductors have led to wrong indications, as this non-conductive paint or coat acts as a capacitor with different capacity according to the thickness. This capacity has an effect on the threshold voltage. b) A contact probe is introduced as a new type of non-conductive contact electrode. c) A new type "exclusively outdoor type" has been defined and implemented into the requirements and test procedure. d) A selector for voltage and frequency is allowed if foreseeable misuse is excluded. e) The marking for voltage detectors with low interference voltage has been made more precise. f) The indication groups have been made more precise and requirements and tests for the "ready to operate state" and "stand-by state" added. g) Requirements and tests for electromagnetic compatability have been implemented. h) An example for good electrical connection for the tests is introduced.

IEC 61472-2:2021 specifies a method for determining the electrical component of the minimum approach distances for live working, for AC systems 1 kV up to and including 72,5 kV.

This document does not indicate values of protection from the effects of the electric arc, because any value indicated would not guarantee the necessary protection from the effects of electric arcs, or the operator would need to wear very heavy and rigid conductive clothing, which would not allow the execution of the work in safety. The products designed and manufactured according to this document contribute to the safety of the users provided they are used by persons trained for the work, in accordance with the live working methods and the instructions for use. This third edition cancels and replaces the second edition, published in 2002. This edition constitutes a technical revision.

For the purpose of this standard, “tube” is used for “tube” and “rod”. Annex B includes considerations about the use under wet conditions. NOTE It is a general practice to use an insulating stick on d.c. installations with the same value of nominal voltage. That use shall comply with the national regulations.

IEC 61230:2008 is applicable to portable equipment, with or without matching connection points, for temporary earthing or earthing and short-circuiting of electrically isolated or de-energized a.c. and d.c. installations, distribution and transmission networks, whether they are overhead or underground or of low or high voltage. This standard covers equipment comprising an earthing or a short-circuiting or an earthing and short-circuiting device and insulating component. The performance of equipment, devices and components covered by this standard is based on electro-dynamic and electro-thermal effects acting during short-circuit. The withstand capability of the devices and equipment is expressed by their rated values of current, time and peak factor. No rated voltage is given, but the geometrical dimensions of the equipment are also linked to the voltage of the installation. This second edition cancels and replaces the first edition published in 1993. It constitutes a technical revision. The major changes are: - extension of the scope to cover the use of equipment on d.c. installations; - extension of the use of aluminium to all conductive parts of the device; - possibility of using this standard for separate components of the equipment; - general revision of requirements and tests; - revision of existing annexes; - introduction of a new informative Annex D giving guidelines for determination of the equivalent r.m.s. value of a short-circuit current and of a new normative Annex F on classification of defects.

This European Standard is applicable to cable cutting devices to be used to verify that a cable is dead in accordance with the rules given in EN 50110 1. The following limits apply to the cable cutting devices: - pressure less than 1 000 bar or pressure (bar) x volume (l) less than 10 000; - fluid outside the categories listed in Article 9 Group 1 (explosive, extremely flammable, highly flammable, flammable (where the maximum allowable temperature is above flashpoint), very toxic, toxic, oxidizing) of the Pressure Equipment Directive. Cable cutting devices specified in this standard are for use on systems with nominal voltage up to 30 kV AC and nominal frequencies up to 60 Hz and shall only be suitable for operation by foot or by hand. This European Standard does not deal with motorised cable cutting devices. For devices to be used on systems with nominal voltages above 30 kV AC this standard should be used as a guide but additional requirements and tests shall be agreed between manufacturer and customer to provide for an equivalent level of safety. These devices are not designed to be used on cables with special armour, or with steel wires or steel tapes more than 1 mm in diameter or thickness.

Is applicable to mobile insulating hoses with fittings used with hydraulic tools and equipment for live working at nominal voltages exceeding 1 kV r.m.s. at power frequency. Insulating hoses with fittings are used to provide a connection between the hydraulic tool and the pump which are at different potentials. They are not considered as a fixed component of a live working device (e.g. aerial device). They can be connected and disconnected under negligible pressure. They can be directly handled by the user.

This European Standard applies to conductor cars which are used for driving (travelling) on conductors, shield wires or shield wires with integrated communication systems of overhead transmission lines.

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. 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.

Is applicable to: - insulating gloves and mitts which should normally be used in conjunction with leather protector gloves worn over the insulating gloves to provide mechanical protection; - insulating gloves and mitts usable without over-gloves for mechanical protection. Unless otherwise stated, the use of the term glove includes both gloves and mitts. The use of the term insulating gloves designates gloves providing electrical protection only. The use of the term composite gloves designates gloves providing electrical and mechanical protection.

Is applicable to fully insulating spliced or hook ladders with extension or having a combination of insulating and conductive sections and 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. This standard concerns only ladders made of synthetic material. These ladders are used, to provide access, generally on overhead line structures and to facilitate live working, either hot stick, barehanded or a combination of both.
