EAD 280001-00-0704 Preassembled line unit used for drainage of infiltration 预制排水或过滤管线单元
Preassembled line unit used for drainage or infiltration. Two possibilities are presented:
The preassembled linear unit comprises a horizontal corrugated slotted or perforated pipe of polyethylene, EPS aggregates that are held surrounding the pipe by means of a netting and a geotextile which covers at least the upper two thirds of the outer surface. The units are set end to end by plastic couplers.
The preassembled linear unit comprises EPS aggregates that are held by means of a netting and a geotextile which covers at least the upper two thirds of the outer surface. The units are not set end to end.
In both cases the unit length varies between 2 and 12 m. The outer diameter of the plastic pipes is in the range between 70 and 200 mm. The outer diameter of the preassembled lineunit is in the range between 225 and 450 mm. An example of dimensions of the EPS aggregate is included in the annex B.
The following table shows the possible product combinations in accordance with the product parameters and intended use possibilities.

预制排水或过滤管线单元欧盟ETA认证－认证体系
System 1 或者 System 3
ETA认证与CPR指令CE认证的关系
Under the CPR, harmonised technical specifications are harmonised European product standards (hENs) established by CEN/CENELEC2 or European Assessment Documents (EADs) produced by the European CPR指令认证的依据是建筑指令欧盟协调标准或欧盟评估文件（EADs）
European Organisation for Technical Approvals (EOTA) as the basis for issuing ETAs for products not covered by hENs.The harmonised technical specification for a product defines EEA-wide methods of assessing and declaring 对于没有被协调标准完全覆盖的建筑产品的认证，可以通过EOTA机构核发ETA认证证书（等同于CE认证书）。 南京睿督授权合作实验室同时为欧盟NB及TAB机构，可以同时受理建材欧盟CE认证和欧盟ETA认证。南京睿督为客户提供专业合规的欧盟CE认证和ETA认证，减少认证中间沟通环节，权威省时省力。
