The difference between EN20471 and EN471

As of October 1, 2013, the European Commission has decided that EN ISO 20471: 2013 "High Visibility Apparel - Test Methods and Requirements" will supersede EN471: 2003 + A1: 2007 "Dedicated High Visibility Warning Tester - Test Methods and Requirements" as EU harmonization of safety reflective clothing standards. As of October 1, 2013, all EEC certificates of safety reflective clothing tested to EN471 will be ineffective; all safety reflective clothing shall comply with the requirements of EN ISO 20471: 2013 before placing on the EU market. Upon request, the main differences between the new EN ISO 20471: 2013 Reflective Clothing standard and the old EN 471: 2003 + A1: 2007 standard mainly include the following seven aspects:
First, after the cleaning cycle should meet the color and brightness requirements;
Second, perspiration stain fastness stained staining requirements will be changed from 3 to the lowest 4;
Third, the tensile strength of woven materials required to change to a minimum of 100 cattle;
Fourth, the rupture strength of the knitted material is required to be at least 100 kPa (50 cm 2 test area) and 200 kPa minimum (7.3 cm 2 test area);
Fifth, the physical properties of single or multi-layer garment testing, breathable index (RET) can not be greater than 5 square meters per watt. If the air permeability index exceeds 5 square meters Pa / Watt, must measure and determine imt ≥ 0.15;
Sixth, there is no distinction between the performance levels of reflective materials, the same requirements as Level 2 of EN 471;
Seven is the new sign change.
