德国MPA认证流程问答
MPA认证是德国MPA机构专门针对磨料磨具产品的安全性能的认证
德国事故预防条例UVV VBG49规定了磨料磨具的安全要求。当企业在德国经营或使用磨料磨具时，产品必须满足以上条例规定。符合这项规定的产品，在以往可以取得DSA编号。由于德国内部的调整，现在由德国国家材料检验局（MPA）负责发证工作
各类转动工具、刷具和切割工具出口欧洲，必须持有MPA安全证书（替代DSA证书）由德国MPA实验室颁布的MPA证书具有绝对的权威性。每一份MPA证书都有防伪标记，且可在相关网站上查询，严格杜绝仿冒，最大限度保护了您们的合法权益。
MPA磨具安全认证产品包括金刚石锯片、树脂砂轮片、木工锯片、磨轮、陶瓷砂轮、百页轮、钢纸砂盘等
CEN要遵循CEN/CENELEC国内规章，规定了赋予该欧洲标准以一个国家标准而无任何变更的条件，关于这些国家标准的更新列表和参考书目，可以向中央秘书处或任何CEN成员申请得到。
此欧洲标准存在三种正式译文（英语、法语、德语），在一个CEN成员负责情况下，译成其他语言，并通报了中央秘书处的译文，拥有与正式译文相同的地位。
CEN成员是以下国家的国家标准组织：奥地利、比利时、捷克斯洛伐克共和国、丹麦、芬兰、法国、德国、希腊、冰岛、爱尔兰、意大利、卢森堡公国、荷兰、挪威、葡萄牙、西班牙、瑞典、瑞士和英国。
树脂砂轮片：EN12413；金刚石锯片 EN13236；硬质合金锯片：EN847-1；磨片EN13473
EN13473:2001 Safety requirements for coated abrasives (磨片）
This European Standard was approved by CEN on 26 October 2001.
CEN members are bound to comply with the CEN/CENELEC Internal Regulations which stipulate the conditions for giving this European
Standard the status of a national standard without any alteration. Up-to-date lists and bibliographical references concerning such national
standards may be obtained on application to the Management Centre or to any CEN member.
This European Standard exists in three official versions (English, French, German). A version in any other language made by translation
under the responsibility of a CEN member into its own language and notified to the Management Centre has the same status as the official
versions.
CEN members are the national standards bodies of Austria, Belgium, Czech Republic, Denmark, Finland, France, Germany, Greece,
Iceland, Ireland, Italy, Luxembourg, Netherlands, Norway, Portugal, Spain, Sweden, Switzerland and United Kingdom.
