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 1000h 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 5cm wide) shall be:

  • warp 100daN
  • weft 60daN

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>=1000N(1daN=10N),纬纱方向>=600N,测试标准是EN-ISO-1421,样品长度为5cm(2 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 24h loading 250N on 100mm, on sample 100mm x 1200mm, warp way and weft according to annex A. shall be within the following limits:
  • Total change in length under load:
  • warp< 12mm
  • weft< 41mm
  • Residual length, load released:
  • warp< 1mm
  • weft< 16mm
  • Residual width, load released:
  • warp 0mm
  • weft 0mm

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 24h in demineralized water, changed completely every 3h.

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%
