BS-EN-13561户外遮阳行业认证标准解读

2016-10-26 16:29:23 苏州泰能纺织科技有限公司 阅读

BS-EN-13561 2004是英国标准学会(Britain Standard Institute,简称BSI)制订的关于户外遮阳行业的认证标准,欧盟通用,同时在全球的认可度非常高。

下面是关于其中面料部分的原文和我们一些简单的解读:

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,以下所有的测试都要基于这个标准,就是按照EN-ISO-105-B04将面料曝晒1000小时,下面各个子项分别测试之前和之后的样品性能数据,并做比较,得出结论。

15.2.2   Colour fastness

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

这部分是关于色牢度,要求达到级别4,测试标准是EN-20105-A02,由德国标准化学会定制,色牢度共5级别,其中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.

这部分是关于抗拉力测试,要求经纱方向>=1000N1daN=10N),纬纱方向>=600N,测试标准是EN-ISO-1421,样品长度为5cm2 inches

同时根据15.2.1的测试,曝晒1000小时后,抗拉力的性能跟初始状况相比不能下降超过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

这部分是形态稳定性的测试,首先是根据15.2.1的测试,经纬向的变化不能超过标准要求;其次是取100mm*1200mm的样品,承受250N的压力,经过24小时,经纬向的变化不能超过标准要求。

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 %.

这部分关于防水性能,根据EN-20811标准做喷淋实验,其中接缝部分不做要求。

做完前面的实验后,将样品浸入脱矿物质的水中24小时,每3小时将水全部更换一遍,跟初始状态相比,防水性能下降不能超过15%
