Overview
DIN EN ISO 11363-2 specifies types, dimensions and principles of use of gauges, to be used in conjunction with the taper threads specified in ISO 11363-1 (that means 17E and 25E threads). Annex A contains examples of calculations for thread gauge dimensions on the large end diameter and Annex B draws attention to the limitations of the gauging system specified in this standard.
