BYGG& ANLÄGGNING 87 Guide EN 343 Clothing that carries an EN 343 certification is tested for protection against bad weather. The latest version of EN 343:2019 involves testing seams for water penetration in classes 1-4 and resistance to water vapor classes 1-4, with 4 being the highest class. The garments must achieve results on both tests to be labeled with the EN 343 symbol. - Protection against ingress of water: 1-4, where class 4 gives the best waterproofness - Water vapor resistance (breathability): 1-4, where class 4 provides the best breathability - Effect of high pressure water drops from above (this is optional) The results are affected by the construction of the garment, where an unlined garment can achieve EN 343 4/4 while a lined garment with the same outer fabric (but with a lining that affects the penetration of moisture) only achieves EN 343 4/1. The previous standard only had 3 classes, these have now been expanded with a fourth class that requires a higher result. Garments certified according to EN 343 continue to apply. PROJOB Workwear will continuously update certified garments. Water resistance (WP) Class 1 ≥ 8000 Pa Class 2 ≥ 8000 Pa material after pretreatment Class 3 ≥ 13,000 Pa material after pretreatment Class 4 ≥ 20,000 Pa material after pretreatment Water vapor resistance (Ret) The breathing function is indicated in RET value. At a lower RET value, the better respiratory function. Class 1 Ret > 40 Class 2 25 < Ret ≤ 40 Class 3 15 < Ret ≤ 25 Class 4 Ret ≤ 15 FUNCTIONALCLOTHES &UNDERWEAR
