DIN 2275:2014-03

This standard applies to feeler gauges and feeler gauge sets of steel with a minimum length of 100 mm. It specifies dimensions and tolerances for feeler gauges as well as the most commonly found feeler gauge sets. Compared with the previous edition, an additional tolerance class (TC2) has been included, whose values have been based upon the dimensions of the basic material the German steel industry can deliver. Thus, manufacturers will be able to produce a significantly greater percentage of their feeler gauges in compliance with the standard (either tolerance class 1 or tolerance class 2). This standard has been prepared by Subcommittee NA 152-03-02-07 UA "Längenprüftechnik außer Koordinaten-, Form- und Oberflächenmesstechnik sowie Gewindekenngrößen" ("Length checking practice except coordinate, form and surface measuring technology as well as characteristics of screw threads").
