EAD 330014-00-0601 Metal expansion fastener for use in autoclaved aerated concrete EAD 330014-00-0601 蒸压加气混凝土用金属膨胀螺丝ETA认证
EAD 330014-00-0601加气混凝土用金属膨胀螺栓欧盟ETA认证－适用范围
This EAD 330014-00-0601 covers post-installed deformation-controlled expansion fasteners placed into pre-drilled holes perpendicular to the surface (maximum deviation 5°) in autoclaved aerated concrete (AAC) and anchored therein by mechanical interlock. Metal expansion fasteners are made of galvanized and/or coated steel, stainless steel or high corrosion resistant steel. This EAD covers only fasteners with steel strength less than 1000 N/mm2 and hardness smaller than 350 HV referring to the total cross section for both surface and core hardness according to EN ISO 6507; < 36 HRC according to EN ISO 6508. The fasteners are described by the manufacturer by reference to dimensions (external/internal diameter, thread length, diameter of shaft, cone etc.) and mechanical properties (tensile and yield strength, fracture elongation) including possible tolerances.
Resistance in any load direction without lever arm 无杠杆臂时任何负载方向的阻力 Resistance under shear load with lever arm 杠杆臂在剪切载荷下的阻力 Spacing, edge distance, member thickness 间距、边距、构件厚度 Displacements 移位 Durability 耐久性 Reaction to fire 防火等级
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）。
欧盟公告NB机构&TAB机构-捷克TZUS (NB1020)介绍
TZUS是欧盟公告号机构，其欧盟公告号为1020(Notified Body 1020-NB1020)。可以根据欧盟相关规定来签发CE证书。 TZUS同时也是ETA(European Technical Approval)的认证委员之一，可以根据相关法规来签发ETA证书。
