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)。
