5、nik sowie Gewindekenngren of the Normenausschuss Technische Grundlagen (NATG) (Fundamental Technical Standards Committee). 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, manufa

6、cturers 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). Feeler gauge tapes are not covered by this standard. Because feeler gauge tapes are produced in various widths and lengths (often

7、 coiled), standardization was not deemed practical. Upon agreement, the values in Table 1 or as in DIN EN 10140 may be applied to the tolerances of feeler gauge tapes. Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. DIN shall not

8、be held responsible for identifying any or all such patent rights. Amendments The standard differs from DIN 2275:1977-09 as follows: a) the values of the tolerances in tolerance class 1 (TC1) have been changed for specific nominal thicknesses to correspond more closely with the rounded theoretical v

9、alues; b) the tolerance class 2 (TC2) has been included; c) tolerances have been specified with reference to the nominal thickness; d) the designation of a feeler gauge set with a special configuration has been included; e) the standard has been editorially revised.

It specifies dimensions and tolerances for feeler gauges as well as the most commonly found feeler gauge sets. 2 Feeler gauges 2.1 Dimensions and designation

18、eeded. 3 Feeler gauge sets 3.1 General A feeler gauge set consists of feeler gauges (see Clause 2) of varying nominal thicknesses s and an appropriate holder. The holder is to be furnished with a clamp which allows the feeler gauges to be fixed in a fan-shaped position (see Figure 2). The most commo

19、n and useful feeler gauge set configurations are listed in Table 2. Additional variations of feeler gauge sets with a special configuration may be agreed upon between the supplier and purchaser.
