About FWS

The DIN Standards Committee Tools and Clamping Devices (FWS) is responsible for the standardization on national (DIN), European (CEN) and international (ISO) level in the fields of tools, clamping devices, abrasive products, stationary grinding machines, and operating elements.

How is FWS composed?

Product properties/company codes according to DIN 4000-1:2019-03

The “Merkmaldateien von DIN”, (DIN property files) were developed for applications mainly in the ERP and PDM environment.

In addition to data from the relevant product standards, they also contain the definitions from the assigned lists of product properties according to the standards of the DIN 4000 ff. series. The “Merkmaldateien von DIN” can be used to build up and manage master data and to develop classification systems.

The open ASCII structure allows the addition of company-specific features such as identification number, storage location, supplier, etc.

The company codes provided in the “Merkmaldateien von DIN” according to DIN 4000-1:2019-03 "Tabular layouts of properties - Part 1: Concepts and principles" are managed by DIN. These are alphanumeric identifiers of up to 4 digits which, in conjunction with the country abbreviation "DE", applies exclusively in Germany.
