DIN/ EN/ ISO DIFFERENCES IN BOLTS
DIN/ EN/ ISO 区别
Gain an insight into the difference between DIN, EN and ISO standards
深入了解DIN、EN和ISO标准之间的差异
This part is intended to assist you in the changeover from withdrawn DIN standards to current EN and/or ISO standards. Information is given on which changes of the respective product standard are relevant for application.
本部分旨在帮助您从废止的DIN标准转换为现行的EN和/或ISO标准,提供了与应用相关的产品标准变更信息。
Product descriptions and product changes
Many DIN standards have been the basis for ISO standards. There have often been minor adjustments when the previous DIN standards have been changed to current ISO standards.
If an ISO standard is implemented on national level without any changes, the same designation as the corresponding ISO standard is given to the national standard. Only the abbreviations DIN EN are added to the designation. This means that an ISO nut is ISO 4032-M12-8 all over the world. Thus, the German version of the standard is called DIN EN ISO 4032-M12-8.
许多DIN标准已成为ISO标准的基础。当以前的DIN标准更改为当前的ISO标准时,通常会有一些小的调整。
如果ISO标准在国内实施而没有任何变化,则该国家标准将被赋予与相应ISO标准相同的名称。仅在名称中添加缩写DIN EN。这意味着ISO螺母在世界各地都是ISO 4032-M12-8。因此,本标准的德语版本称为DIN EN ISO 4032-M12-8。
Standardization
In the past, standardization activities at national level have been realized by the German Institute for Standardization (Deutsches Institut für Normung e. V. = DIN) in Germany. Furthermore, there are EN standards at European level and ISO standards at international level which are published by the International Organization for Standardization.
过去,德国标准化研究所(Deutsches Institute für Normang e.V.=DIN)在德国开展了国家级的标准化活动。此外,还有由国际标准化组织(international Organization for standarization)发布的欧洲级EN标准和国际级ISO标准。
Hexagon head bolts 六角头螺栓
Most DIN standards for these bolt types have been withdrawn years ago. The successor ISO standards largely comply with the DIN standards withdrawn. Therefore, there are normally no restrictions on use. You only have to note that different sizes of fastening tools have to be used for the dimensions M10, M12, M14 and M22. The dimensions for the widths across flats are shown in table.
大多六角头螺栓的DIN标准已在多年前废除。后续ISO标准基本上符合已废止的DIN标准。因此,通常没有使用限制。您只需注意尺寸M10、M12、M14和M22的对边宽度不同,必须使用不同尺寸的紧固工具。对边宽度的尺寸如下表所示 :

Other screw and bolt types 其他螺栓
Studs 双头螺栓
The DIN standards for studs are entirely applicable. Currently, there are no successor ISO standards defined.
DIN双头螺栓的的DIN标准完全继续施行, 目前没有后续的ISO标准。
