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）。
