Since October 1, 2013, the European Commission has decided that EN ISO 20471:2013 "high visibility clothing - Test methods and requirements" will replace en471:2003 + A1:2007 "special high visibility warning clothing - Test methods and requirements" as the new harmonized standard of EU safety reflective clothing. From October 1, 2013, the EEC certification of all safety reflective clothing tested according to EN471 will be invalid; All safety reflective clothing should meet the requirements of EN ISO 20471:2013 before being put on the EU market. According to the requirements, the main differences between the new version of EN ISO 20471:2013 standard and the old version of EN 471:2003 + A1:2007 standard mainly include the following seven aspects:
First, after the cleaning cycle, it should meet the requirements of color and brightness;
The second is that the dyeing requirement of color fastness to perspiration will be changed from grade 3 to grade 4;
Third, the tensile strength of the braided material should be changed to lower 100 n;
Fourth, the breaking strength of knitted materials should be changed to at least 100 kPa (50 square centimeter test area) and lower 200 kPa (7.3 square centimeter test area);
The fifth is the physical performance test of single-layer or multi-layer clothing. The air permeability index (RET) should not be greater than 5 square meters PA / watt. If the air permeability index exceeds 5 M2 PA / W, it must be measured and determined;
Sixth, there is no distinction between the performance levels of reflective materials, and the requirements are the same as the level 2 of en 471;
