    DIN/ EN/ ISO DIFFERENCES IN PINS & SET SCREWS
    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    This part is intended to assist you in the changeover from withdrawn DIN standards to current EN and/or ISO standards.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。

    主要是各类销子、键、无头螺钉(紧定螺钉)、管堵DIN\EN和ISO之间的变更情况及差异

    Taper and parallel pins 锥销和柱销

    All DIN standards for taper and parallel pins have been withdrawn and replaced by EN or ISO standards.The succes-sor standards sometimes have different length definitions in comparison to the withdrawn DIN standards.Nevertheless,in most cases it is possible to substitute DIN parts without major design changes.For example,the specification of the nominal lengths of taper pins according to DIN 1 and parallel pins according to DIN 7 is without round ends.In the successor standards EN 22339 and ISO 2338 the whole length of the pin is used to define the nominal length. that means round ends and chamfers are included.

    所有的锥销和柱销的DIN标准均已由EN或ISO标准所替代,与旧的DIN标相比有些长度上的要求有所改变。 然而在大多数情况下DIN的替代品并没有做出重大的设计上的改变。 例如:DIN 1和DIN 7所规定的销子的公称长度是不包含圆形尾端的,但替代标准EN 22339和ISO 2338的整体长度定义是包含圆形倒角的尾端的。

    Spiral pins 卷销

    All DIN standards for spiral pins/roll pins have been withdrawn and replaced by successor ISO standards.In this context, the possible use of spring pins/roll pins in bolted connections,which was allowed according to some DIN standards, has been deleted. In most cases, it is possible to substitute spiral pins according to DIN standard by spiral pins according to ISO standard.

    所有卷销的DIN标准均已作废并由ISO标准所替代.。在这种情况下,一些原DIN标准所允许的用于螺栓连接的弹性销/卷销的可行性已被取消。 大多数情况下,是可用IS0标准的卷销来替代DIN标准的卷销来使用的。

    Clevis pins 定位销  

    The DIN standards for clevis pins have been withdrawn and replaced by EN standards. As they only show minor changes in comparison to the successor EN standards, they are interchangeable.

    定位销的DIN标准已经废止并被EN标准取代。由于与后续EN标准相比,它们只显示出微小的变化,因此它们是可互换的。

    Others 其他销与键

    Set screws  紧定螺钉 

    The DIN standards for set screws are replaced by successor ISO or EN standards. There are only slight changes in application.

    紧定螺钉(开槽紧定螺钉及内六角紧定螺钉)的DIN标准已经被后续的ISO标准所替代,但只有很微小的更改。

    Screw plugs 管堵

    The DIN standards for screw plugs are entirely applicable. Currently, there are no successor ISO standards defined.

    管堵的DIN标准仍在完全施行 , 目前无替代的ISO标准。
