2、on. European Standard EN 22 339 : 1992 has the status of a DIN Standard. A comma is used as the decimal marker. National foreword The publication of this standard is in keeping with a decision made by CEN/TC 185 to adopt, without alteration, a series of IS0 Standards covering parallel and taper pins

3、 as European Standards. The responsible German body involved in their publication is the Normenausschu Mechanische Verbindungselemente (Fasteners Standards Committee). As a consequence, all DIN Standards covering such pins have been superseded by the corresponding DIN EN Standards (see table below).
