European Standard EN 22 340 : 1992 has the status of a DIN Standard. A comma is used as the decimal marker. National foreword The publication of this
3、 standard is in keeping with a decision made by CEN/TC 185 to adopt, without alteration, a series of IS0 Standards covering clevis pins and washers for use with clevis pins as European Standards. The responsible German body involved in their publication is the Normenausschu Mechanische Verbindungsel
4、emenfe (Fasteners Standards Committee). As a consequence, all DIN Standards covering such pins and washers have been superseded by the corresponding DIN EN Standards (see table below).
