 深入了解 DIN、EN和ISO标准之间的差异

Normally standards are reviewed every five years to check if they are still state of the art. This is an important measure, even from the legal point of view. Complaints or even claims often arise due to the ignorance or non-compliance with current standards and the included cross references.

标准通常每五年审查一次，以检查它们是否仍然是最先进的。这是一项重要的措施，即使从法律的角度来看也是如此。投诉甚至索赔通常是由于不了解或不符合现行标准和所包含的交叉引用。

In recent years, a large number of DIN standards have been replaced by international DIN EN ISO standards. For industry companies it is  indispensable to know which standards are valid and which are withdrawn. If repairing is necessary, the customer or the service mechanic should be able to obtain appropriate fasteners being state of the art.

近年来，大量的DIN标准被国际 DIN-EN-ISO 标准所取代。对于工业公司来说，了解哪些标准有效，哪些标准被废止是必不可少的。如果需要修理，客户或维修技师应能够获得最先进的紧固件。

Here you can find information on what changes have been made to the respective product standard and what differences between the DIN, EN and ISO standards this has caused. Get an overview and use the clear direct comparison of the withdrawn DIN standards and the current EN and ISO standards.
In the past, standardisation work in Germany was carried out on a national level by Deutsches Institut für Normung e. V. (DIN). On a European level there are also EN standards, as well as ISO standards on an international level, which are issued by the International Organization for Standardization.

过去，德国的标准化工作是由德国标准化协会（DIN）在国家层面上开展的。在欧洲，还有欧洲标准化组织（international Organization for standarization）发布的欧洲标准（EN）和国际标准化组织（ISO）标准。

 The Differences 区  别

DIN

National standards (DIN) are largely being replaced by international and European standards. DIN standards are now only issued for products that have no ISO or EN standards

国家标准（DIN）在很大程度上正被国际和欧洲标准所取代。DIN标准现在只适用于没有ISO或EN标准的产品。

ISO

In accordance with the task and objective of the ISO, which was founded in 1946, international standards (ISO) are intended to standardise technical rules worldwide, thus simplifying the exchange of goods and removing trade barriers.

根据成立于1946年的国际标准化组织的任务和目标，国际标准化组织旨在使世界范围内的技术规则标准化，从而简化货物交换和消除贸易壁垒。

EN

The purpose of European standards (EN) is to harmonise technical rules and laws within the single European market that was jointly established on 01/01/1993. As far as possible, existing ISO standards must generally be adopted as EN standards in unaltered form. The difference between ISO and EN standards is that, following the decision of the European Council, EN standards must be adopted and implemented immediately and without any changes as national standards in the member states, and, at the same time, the corresponding national standards must be withdrawn.

欧洲标准（EN）的目的是协调1993年1月1日共同建立的单一欧洲市场内的技术规则和法律。在可能的情况下，现有的ISO标准通常必须采用不变的形式作为EN标准。ISO和EN标准之间的区别在于，根据欧洲理事会的决定，EN标准必须作为成员国的国家标准立即采用和实施，不得有任何变化，同时，必须废止相应的国家标准。
