Amendment DIN 11864/11853 | 06-19-2025

A new version of the two above-mentioned standards was published in 2024 and April 2025. The changes are minor and mainly concern the inner diameter and the designations (see attached excerpt from the standard). However, there are no changes to the gasket geometries, so the proven sterile and hygienic properties remain unchanged.

As AWH, we will implement these necessary adjustments step by step, among other things by adapting drawings and selling off stock. During the transition phase, you may therefore find different designations on the components.

All article numbers will remain unchanged, so no changes or adjustments will be necessary in your ERP system. In the sales texts, we will adapt some terms to the new standard language, for example “Bundstutzen” has now become “Nutstutzen” with the abbreviation “VN”.

We are doing everything we can to make the transition period as short as possible in order to quickly achieve a uniform standard again.

If you have any further questions, please do not hesitate to contact us.
