EAD 280001-00-0704 Preassembled line unit used for drainage of infiltration 預製排水或過濾管線單元
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.

ETA認證與CPR指令CE認證的關係
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指令認證的依據是建築指令歐盟協調標準或歐盟評估檔（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 對於沒有被協調標準完全覆蓋的建築產品的認證，可以通過EOTA機構核發ETA認證證書（等同於CE認證書）。
