BS-EN-13561 2004是英国规范学会(Britain Standard Institute,简称BSI)制定的关于户外遮阳行业的认证规范,欧盟通用,同时在环球的承认度十分高。

上面是关于此中面料局部的原文和我们一些复杂的解读:

Fabric

15.2.1   General

With reference to the initial state, performances shall be estimated after 1000 h exposure to weathering agents according to EN ISO 105-B04.

这个一个通则,以下一切的测试都要基于这个规范,便是依照EN-ISO-105-B04将面料曝晒1000小时,上面各个子项辨别测试之前和之后的样品功能数据,并做比拟,得出结论。

15.2.2   Colour fastness

The grey scale according to EN 20105-A02 shall be at least at level 4.

这局部是关于色牢度,要求到达级别4,测试规范是EN-20105-A02,由德国规范化学会定制,色牢度共5级别,此中1最低,5最高。

15.2.3   Tensile resistance

-The minimale tensile resistance carried out according to EN ISO 1421 (on strip of 5 cm wide) shall be:

-warp     100 daN

-weft      60 daN

-The reduction of resistance shall not be more than 20 % relative to the initial state.

这局部是关于抗拉力测试,要求经纱偏向>=1000N1daN=10N),纬纱偏向>=600N,测试规范是EN-ISO-1421,样品长度为5cm2 inches

同时依据15.2.1的测试,曝晒1000小时后,抗拉力的功能跟初始情况相比不克不及降落超越20%

15.2.4   Dimensional stability

-Stability under weathering agents : dimensional variations shall be between the following limits:

-warp [-3 % , +1 %]

-weft : [-1 % , +1 %]

Residual deformations after traction application : dimensional variations measured after 24 h loading 250 N on 100 mm, on sample 100 mm x 1 200 mm, warp way and weft according to annex A. shall be within the following limits:

-Total change in length under load:

-warp < 12 mm

-weft < 41 mm

-Residual length, load released:

-warp < 1 mm

-weft < 16 mm

-Residual width, load released:

-warp 0 mm

-weft 0 mm

这局部是形状波动性的测试,起首是依据15.2.1的测试,经纬向的变革不克不及超越规范要求;其次是取100mm*1200mm的样品,接受250N的压力,颠末24小时,经纬向的变革不克不及超越规范要求。

15.2.5   Resistance to water penetration:

Resistance to water penetration (Schopper test) shall be measured according to EN 20811. Stitches are not concerned.

A new measurement is taken after simulation of effect of repeated showers.

The sample is immersed during 24 h in demineralized water, changed completely every 3 h.

The reduction of the resistance to water penetration shall not be more than 15 %.

这局部关于防水功能,依据EN-20811规范做喷淋实行,此中接缝局部不做要求。

做完后面的实行后,将样品浸入脱矿物质的水中24小时,每3小时将水全部改换一遍,跟初始形态相比,防水功能降落不克不及超越15%
