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***的认可度非常高。

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***低，5***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>=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 variati*** shall be between the following limits:
-warp [-3 % , +1 %]
-weft : [-1 % , +1 %]
- Residual deformati*** after traction application : dimensional variati*** 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小时将水更换一遍，跟初始状态相比，防水性能下降不能超过15%
