关于PMA的一点发现? As required by the Pressure Equipment Directive 97/23/EC (PED) Annex I section 4.2, the pressure equipment manufacturer is responsible for preparing documentation for materials to be used for pressure equipment in categories I to IV. For pressure equipment in categories III and IV this documentation is submitted to the Notified Body in charge of the conformity assessment for the equipment so they can perform an appraisal of the particular material with regard to the pressure equipment, the intended use and applicable design rules. 对于III类与IV类承压容器,要向负责设备的符合性评估的认证机构提交文件,由其进行承压设备,应用方向与适用设计规则有关的某个特定材料的评估。 昨天还是在做管路冲洗的东西,今天又被拉来做PMA的东西了,哈哈,对这个东西不是太懂 [ ]查看更多1个回答 . 4人已关注
