FASTENER STANDARDS CONVERSION

The conversion of some national DIN standards to ISO or EN standards is (was) done with the aim of deconstructing trade barriers in international goods exchange and harmonising the technical rules in the common single European market.

Table 1 shows the ISO/EN standards for product standards and the most important thread and basic standards according to the corresponding DIN in ascending order (as of: Nov. 2009).

Table 2 (next page) shows the EN and DIN standards according to the corresponding ISO in ascending order.

The tables also include draft standards and withdrawn standards.

Standard types, relations, publishers:

National German standard (Deutsches Institut für Normung).

DIN standards shall still be given for the products/services for which there are no ISO/EN standards and no standardisation necessity.

ISO

International Standardization Organisation

DIN ISO

National German issue of an unmodified, adopted ISO standard

EN

European Norm (CEN = Comité Européen de Normalisation). In general, existing ISO standards should be adopted as EN standards with the ISO standard number ? EN ISO.

If this does not happen at European standards levels, independent EN standards shall be generated with EN standard numbers which are different to those of the ISO

DIN EN

National German issue of an unmodified, adopted EN standard. According to the resolution of the European Council, EN standards are to be adopted unmodified and immediately by the EU member states and the corresponding national standards are to be withdrawn.

EN ISO

European standard issue which was adopted unmodified by ISO (EN and ISO standard numbers are identical - the earlier practice of "ISO number + 20,000" has not been in use since Jan. 95.

Standards still in use according to this mode are to be converted accordingly).

DIN EN ISO

National German issue of an unchanged EN standard adopted by ISO.
The article naming is done according to ISO.
