如题，那位老师可以科普下EN标准制定流程？
DOR和DAV有什么联系？DOA和DOP有什么联系？
网上了解到一些相关的信息如下：
EN标准有5个节点日期，分别为：DOR(核准日期），DAV(生效日期），DOA(宣布日期），DOP(发布日期），DOW(撤销日期）。
具体含义如下：
DOR(date of ratification)=date the CENELEC Technical Board notes the approval of an EN or HD,from which time the standard may be said to be adopted
核准日期：CENELEC技术委员会核准此EN或HD通过的日期
DAV(date of availability)=date when the definitive text in the official language versions of an approved EN or HD is distriputed by the CENELEC Central Secretariat.
生效日期：CENELEC中央秘书处发布以官方语言表示的EN或HD最终确定内容的日期
DOA(date of announcement)=latest date by which the existence of an EN or HD has to be announced at national level by the CENELEC members.
宣布日期：CENELEC会员必须将此EN或HD宣布为国家标准的最后期限
DOP(date of publication)=latest date by which an EN has to be implemented at national level by publication of an identical national standard or by endorsement
核准日期：此EN必须已被发行为国家标准或是被签署的方式导入至各国的最后期限
DOW(date of withdrawal)=latest date by which national standards conflicting with an EN OR HD have to be withdrawn
撤销日期：与此EN或者HD相抵触的国家必须被撤销的最后期限
