從2013年10月1日起,歐盟委員會決定,EN ISO 20471:2013《高能見度服裝-測試方法和要求》將取代EN471:2003+A1:2007《專用高能見度警示服-測試方法和要求》成為歐盟安全反光服的新協調標準。自2013年10月1日起,所有根據EN471測試的安全反光服的EEC驗證證書將失效;所有安全反光服在投放歐盟市場前都應符合EN ISO 20471:2013標準的要求。根據要求,新版EN ISO 20471:2013反光服標準與舊版EN471:2003+A1:2007標準的主要區別主要包括以下七個方面:
一是清洗周期過后應滿足顏色和亮度的要求;
二是耐汗漬色牢度沾色的染色要求將從3級改為最低4級;
三是編織材料的拉伸強度要求更改為最低100牛;
四是針織材料的破裂強度要求改為至少100千帕(50平方厘米的測試面積)和最低200千帕(7.3平方厘米的測試面積);
五是單層或多層服裝的物理性能測試,透氣指數(RET)不能大于5平方米帕/瓦特。如果透氣指數超過5平方米帕/瓦特,必須測量并確定imt≥0.15;
六是反光材料的各項性能級別沒有區分,要求與EN 471的2級一樣;
七是新的標志更改。
EN20471認證適用產品范圍:反光服/反光衣/反光背心/熒光布/反光條/反光材料/交通警示服裝等。
