Wind-resistant jacket with the European standard EN 343 clothing against bad weather

Charge the name origin
Ski-wear, windbreaker, call for more abroad wind jacket windbreaker jacket or windproof jacket wind-proof jacket.
Clothing characteristic
Ski-wear, with waterproof, windproof, through steam (moisture) and by the vast number of consumers love; This feature can also be charge clothing clothing characteristics.
waterproof
Refers to whether you sit in damp places, or walking in the stormy environment, can effectively prevent the invasion of rain and frost and snow, the water cannot penetrate into the clothes make you feel wet and cold.
wind
Refers to prevent air cooling effect of one hundred percent. Under the changeful environment, when the cold wind penetrates our clothes, can blow away our body skin near a layer of warm air, when the cold wind blow clothes and destroyed this layer of warm air, rapid loss in heat, the temperature drops, we will immediately feel a bit cold.
Transparent air ()
Refers to when you are in the great physiological load of exercise or other outdoor sports body's natural sweating, skin breathe out a large number of moisture, if not quickly out of the body, will surely lead to khan gas trapped between the body and the clothes, is soaking wet, in this rainy weather, will feel more wet and cold.
Charge the execution of the standard
Ski-wear, while sales at home and abroad for many years, but has not explicitly ski-wear, domestic product standards; The current standard of outdoor sportswear ski-wear, is still in the approval stage. Now phase of each manufacturer to perform standard is commonly: no filler of charge costumes of the GB/T 81007, clip, filler ski-wear, GB/T 2662 cotton clothing, is generally used to eu standards for EN 343 bad weather protective clothing, due to the standard of our country not out temporarily, first to EN 343 standard for everybody introduction of technical parameters.
The main technical parameters of EN 343
Waterproof performance - hydrostatic test:
Using standard test method for: EN 20811; The rate of pressure rise to 980 + 50 Pa/min
Physical comfort testing - wet resistance (Ret) :
Using standard test method for: EN 31092
Wet resistance is different from the moisture permeability test measure of a physical comfort test; Refers to both sides of the sample water vapor pressure and vertical through the sample of the ratio of evaporation heat flow per unit area, evaporation heat flow may be composed of diffusion and convection one or more of the form. Technical indexes for this I will be explained in the following WeChat; After foreign outdoor with clothes on the technical indicators will be more widely applied, the domestic is still used as a reference by moisture transmission.
Tensile strength test:
Using standard test method for: EN ISO 13934-1
Technical index requirements: > 450 n
Note: do not apply to the elongation is more than 50% of the fabric
Tear strength test:
Using standard test method for the ISO: 4674-1977
Technical index requirements: > 25 N
The size of the protective clothing rate:
Standard test method for using: EN 340
Technical index requirements: plus or minus 3%
Joint strength test:
Using standard test method for: EN ISO 13935-2
Technical index requirements: > 225 n
Note: do not apply to the elongation is more than 50% of the fabric
In the above technical requirements, the most important still is resistant to water pressure test and wet resistance test, the resistance to water pressure can solve the clothing wearing process to the protective effect of rain; Wet resistance can solve the movement process in the body's own sweat, the sweat evaporation rate. General charge of garment fabrics are coating, sticker or compound fabrics; For these fabrics, the effect of the wind are generally obvious, basically belongs to the windtight fabrics, so the assessment of the project is not to be in the standard inspection.
Editor's note
Whether the EN 343 bad weather protective clothing, is our country the upcoming "outdoor sports clothing - ski-wear,"; Or of its products, emphasis the physical comfort of technical indicators. For the moisture transmission (g/m2. 24 h) and wet resistance (Ret) (m2. Pa/W) are corresponding relation temporarily do not make the corresponding contrast test, so I don't know much about it; But no matter how, can emit sweat by personal rapid evaporation, maintain the comfort of the body is the trend of The Times, is also the most intuitive feel consumer product quality the important parameters.
