EN 61482-1-2/IEC 61482-2 - LIVE WORKING – PROTECT
IVE CLOTHING AGAINST THE THERMAL HAZARDS OF AN ELECTRIC ARC (Live working - Protective clothing against the thermal hazards of an electric arc. Part 2: Requirements. EN 61482-1-2/IEC 61482-2 is the first European standard covering protective clothing against electric arcs These standards exist in two classes (see brief comparison below). Code Class 1: Equivalent to 4 kA, 400 volt for 500 ms. The material or garment must not burn for more than 5 seconds, melt through or form holes larger than 5 mm. Class 2: Equivalent to 7 kA, 400 volt for 500 ms. The material or garment must not burn for more than 5 seconds, melt through or form holes larger than 5 mm. Some of the design requirements: - Buttons, zippers etc. must be covered by the electric arc resistant fabric. Other: - IEC61482-2 requires garments to be sewn with flame resistant threads. This is not a requirement for garments complying with the EN 61482-1-2 standard. - Heat Attenuation Factor (HAF) specifies the garment’s ability to block or prevent heat from passing through the fabric. The value indicates the proportion of energy that is blocked by the material. The higher the value, the better the protection. ATPV XX.X Cal/cm² ATPV (Arc Thermal Protective Value) ATPV indicates that the garment/fabric has been arc flash tested according to the EN 61482-1-1/ASTM F1959 standard and provides protection against incident energy, the value of which is given in units of calories per square centimetre. The ATPV shows the lowest rating at which the energy of the electric arc causes the fabric to break open. At this value, there is a 50% probability that sufficient heat will transfer through the garment/fabric to cause a second-degree burn injury based on the Stoll Curve. The higher the value, the better the protection provided by the garment/fabric. When working in an environment where there is the possibility of being exposed to an arc flash, it is important to wear several layers of clothing, e.g. with a flame-resistant base layer, to provide strong protection. EN 13034 Type PB [6] PROTECTIVE CLOTHING AGAINST LIQUID CHEMICALS - PERFORMANCE REQUIREMENTS FOR CHEMICAL PROTECTIVE CLOTHING OFFERING LIMITED PROTECTIVE PERFORMANCE AGAINST LIQUID CHEMICALS (Type 6 and Type PB [6] equipment) The garment should be used together with chemical resistant gloves, boots and other garments that offer protection according to the EN 13034 standard. The protective clothing can be used where there is a risk of minor exposure to chemical splashing/splattering, where a full chemical barrier is not required. Specialist industrial laundering is required for reapplication of the garment; reapplication should be performed after 5 washes to maintain protection. Type PB[6] garments provide partial body protection and have not been subjected to a whole-suit test (5.2). The material has been tested against the following chemicals in accordance with the EN 13034 standard: Sulphuric acid, H2SO4 30%, Sodium Hydroxide, NaOH 10%, O-Xylene, Butan-1-ol. For information and results for repellency and penetration of liquid chemicals (index 1-3, highest level 3) for each garment, please see the information inside the garment. Test Method According to the required standard EN 13034:2005 The following fabric properties have been tested (levels 1-6, with 6 being the highest level): Abrasion resistance Tearing strength (Trapezoid procedure) Breaking strength Puncture resistance Seam strength EN 530-2 ISO 9073-4 EN ISO 13934-1 EN 863 EN ISO 13935-2 Level 1 > 10 cycles Level 1 > 5N Level 1 > 30N Level 1 > 5N Class 1 > 30N EN 381-5 - CHAIN SAW PROTECTION, REQUIREMENTS FOR LEG PROTECTORS EN 381-5 - SÅGNINGSSKYDD, FORDRINGAR FÖR BENSKYDD Klass 1: 20 m/s Klass 2: 24 m/s Klass 3: 28 m/s Garments approved under the EN 381-5 standard are intended for use in logging work / work with chainsaws. There are three classes where the classification describes how the trouser protection withstands the speed of the chainsaw. Choice of design: Designs A and B both cover the front of the legs and are intended for use in normal logging work by professional foresters who are highly-trained and knowledgeable in the field. However, designs A and B differ with respect to the protection on the inside of the leg. See the diagram. Design C covers the whole leg and is intended for use by persons who do not normally work with chainsaws or extraordinary situations, e.g. work in trees. Make sure that the chainsaw protection in the trousers overlaps the chainsaw protection in the footwear. EN 381-5 - SÅGNINGSSKYDD, FORDRINGAR FÖR BENSKYDD Design A Klass 1: 20 m/s Klass 2: 24 m/s Klass 3: 28 m/s Front Back Protective area Plagg godkända enligt EN 381-5 är avsedda att användas vid skogsavverkningsarbete / arbete med motorsåg. Det finns tre klasser där klassningen beskriver hur skyddet i byxan står emot hastigheten på motorsågkedjan. Val av design: Både design A och B täcker framsidan av benen och är avsedd att användas i normalt skogsavverknings-arbete av proffesionella skogsarbetare som är väl utbildade och kunniga inom området. Dock skiljer sig design A och B åt när det gäller skyddet på insidan av benen. Se skiss. Design C täcker hela benen och är till för att användas av personer som normalt inte arbetar med motorsågar eller extraordinära situationer, t.ex vid arbete i träd. Försäkra Dig om att byxans sågskydd överlappar sågskyddet i fotbeklädnaden.
