IEC 61482-2 | Arc Flash Protective Clothing Standards
IEC 61482-2 Arc Flash Standard
ProGARM produces safety garments that protect workers against the Thermals Hazards of an Electric Arc. Each arc flash protective garment is carefully designed by ProGarm to offer the maximum protection to the new arc flash standard IEC 61482 whilst ensuring comfort and outstanding durability.
As Arc Flash clothing items come under the requirements of Category 3 Protective Clothing, these garments are manufactured under Module D Quality Control Procedures.
Electric Arc and the arc flash created is the light and heat produced as part of an arc fault; a type of electrical explosion or discharge that results from a low impedance connection through air to ground or another voltage phase in an electrical system.
The intense heat can create temperatures as high as 19,000°C and it also produces electric shock, force and large quantities of thermal radiant energy.
What is the Risk?Â
In any situation where your employees are working with electricity, an Arc Flash can occur and as such the maximum energy of default circuits in any electrical installation must be able to be determined. The risks of an electric arc exposure are:
Performance requirements for materials and design requirements for garments, plus Marking and User Information.
This part of IEC 61482 is applicable to protective clothing used in work if there is an electric Arc hazard. This standard specifies requirements and test methods applicable to materials and garments for protective clothing worn by electrical workers to protect them against the thermal hazards of electric Arc based on relevant general properties of the textiles, tested with selected textile test methods, and one of the Test Methods as defined below.
‘Open Arc’ test method (ATPV test and garment test). This replaces IEC 61482-1:2002. The ‘Open Arc’ test method is the same as the original North American method for measuring the Arc Thermal Performance Value (ATPV), as used in ASTM F1959. Materials or assemblies are given an ATPV/EBT/ELIM value, expressed in kilojoules per square metre (kJ/m2), which can be converted into the familiar cal/cm2.
Or
‘Box Arc’ test method (Fabric classification and garment test). The ‘Box Arc’ test method is based on the original European method described in ENV 50354, with a heat transfer measurement. Materials or assemblies are classified as Arc Protection Class (APC) 1 (4 kA) or APC 2 (7kA).
During this test, a fabric sample is exposed to an electric Arc produced by a 4kA or 7kA short circuit. In the test, the Arc does not last any longer than 500ms. The amount of heat transmitted through the sample is measured during and after the test. On the basis of the resulting data and a Stoll curve, the length of time it would take to cause the onset of second-degree burns is subsequently determined. Samples are also assessed for after-flaming, hole formation, melting, etc.
GARMENT TESTING & FABRIC TESTING
It is important to note that not only the fabric should be tested for conformance to the Arc Flash Standard, but also the complete garment or garment assembly itself.
The garment test is not testing for energetic value but is testing to ensure that the garment structure remains intact after the Arc exposure and that components such as zippers and buttons are still functional and do not contribute further injury to the wearer by melting or heat transfer.
ProGARM | Functional Arc Flash Clothing, Protection & PPE For Everyday Wear
As a result of this ProGARM have written a short guide to the new IEC 61482-2:2018 standard to highlight the key bits of information you need to be aware of when reviewing your PPE specification and the key terminology that you need to understand.
Choosing the right PPE for your team can be difficult and with all the standards to consider it can feel quite overwhelming. This guide aims to help people make a more informed decision about what PPE is best for you.

Damage to the Cable Jacket & Sheath is a fairly common issue on site.
A cable might be endangered even before deployment: for example, a cable may have been dragged across a concrete floor and snagged. When the Cable Sheath is damaged, the electrical system may become compromised from moisture and contaminants. Even the smallest scratches can be dangerous as they can be deeper than they appear and increase when bending the cable. This is why Cable Jacket Repair methods are paramount.
Cable Jacket Repair with 3M Electrical Tapes
The nature and type of damage to a cable determines which selection of tapes and methods of repair should be used. The tapes may be used to repair scratched or slightly damaged cable jackets, or more substantial repairs; where a section of the cable jacket is missing. Where the conductor or inner parts of a cable’s construction is not damaged, the repair of the cable jacket is possible with the use of 3M tapes. Otherwise, if these parts are damaged, the cable would have to be either spliced or replaced.
In the following circumstances, methods of Cable Jacket repair from 3M, including 3M Scotch Electrical Tapes, can be used
The different levels of cable damage are demonstrated below: with the suggested repair methods for each.
 |
 |
 |
| Damage Level 1 | Damage Level 2 | Damage Level 3 |
| Minor damages. Surface damages like scratches and grooves from sharp edges. | More substantial damages with cable cores intact. Cuts and breakouts of the cable jacket. | A new cable splice is required. Severe damages with damages cable cores. Punctures and deep damages affecting the inner layers of the cable. Further detection of the cable is necessary. |
Rubber Mastic tapes, manufactured by 3M, are the main components of cable jacket repair solutions. These flexible tapes go on smoothly and bond instantly to make electrical repairs in the field an easy task. A mastic adhesive securely adheres to most power cable jacket materials without loosening or separating, delivering a reliable seal that will maintain the integrity of the cable jacket in the long term.
Besides Scotch® Cable Jacket Repair Tape 2234, 3M provides alternative tapes solutions for Cable Jacket repairs with different characteristics. See the table below with the different options.
| 1 | 1. Wrap Scotch® Rubber Mastic Tape 2228 over the scratch. | 2. Then overwrap with Scotch® Super 33+™ Vinyl Electrical Tape over the whole repair length for the mechanical strength. | Scotch® 2228 is softer then Scotch® 2234, it’s not flame retardant and has lower chemical resistance vs. Scotch® 2234. |
| 2 | 1. Wrap Scotch® Rubber Mastic Tape 2228 over the scratch. | 2. Scotch® Heavy Duty Vinyl Electrical Tape 22 over the whole repair length for the mechanical strength. | Scotch® 22 is more robust and thicker than Scotch® Super 33+™, but it’s less abrasion resistant than Scotch® 2234. |
| 3 | 1. Scotch® Mining Tape 31 over the whole repair length. | Very similar characteristics to Scotch® 2234, but even more hard. It was specially designed for the Mining industry. |
Similar to the repair of minor damages, there are alternative solutions to Scotch 2234 tape for substantial damage repairs.
| 1 | 1. 3M™ Scotchfil™ Electrical Insulation Putty into the hole for sealing and moisture protection and restoring the mechanical properties of the cable. | 2. Scotch® Rubber Mastic Tape 2228 over the whole repair length. | 3. Scotch® Super 33+™ Vinyl Electrical Tape on top for mechanical strength. | Scotch® 2228 is softer then Scotch® 2234, it’s not flame retardant and has lower chemical resistance vs. Scotch® 2234. |
| 2 | 1. 3M™ Scotchfil™ Electrical Insulation Putty into the hole for sealing and moisture protection. | 2. 3M™ Scotchfil™ Electrical Insulation Putty over the whole repair length. | 3. Scotch® Super 33+™ Vinyl Electrical Tape on top for mechanical strength. | Only 2 tapes are needed, cheaper option. 3M™ Scotchfil™ is not as easy to apply as Scotch® 2228. |
| 3 | 1. 3M™ Scotchfil™ Electrical Insulation Putty into the hole for sealing and moisture protection. | 2. Scotch® Rubber Splicing Tape 23 over the whole repair length. | 3. Scotch® Heavy Duty Vinyl Electrical Tape 22 on top for mechanical strength. | Scotch® 23 makes the repair place smoother due to its strong radial pressure. |
