DIN/ EN/ ISO 区别
Gain an insight into the difference between DIN, EN and ISO standards
This part is intended to assist you in the changeover from withdrawn DIN standards to current EN and/or ISO standards.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.
Some DIN standards often used, such as DIN 125, have been withdrawn and replaced by the ISO standards 7089 and 7090. Hardness class 140 HV, which has often been used, is no longer included in the successor standards. In any case, it is absolutely necessary to use at least hardness class 200 HV for high-strength screws and bolts of property class 8.8 and higher. This is often ignored in practice.
一些常用的DIN标准，例如DIN125 已经取消并由ISO7089和7090所替代。硬度140HV的常用垫圈已经不包含在后续的ISO标准里，在任何情况下都绝对有必要使用200HV的垫圈 来配合强度等级8.8或更高的螺栓或螺钉， 这一点却常常在实际应用中被忽略。

DIN 6796 is the only DIN standard for locking washers which is still valid. All other DIN standards have already been withdrawn a long time ago. Tests have shown that these products are ineffective in combination with screws or bolts of property class 8.8 or higher.
In combination with screws or bolts up to property class 10.9, DIN standard 6796 can be used to reduce settling.
