A British Standard does not purport to include all the necessar
14、y provisions of a contract. Users of British Standards are responsible for their correct application. Compliance with a British Standard does not of itself confer immunity from legal obligations. Summary of pages This document comprises a front cover, an inside front cover, pages i and ii, pages1 to

This will be indicated in the amendment table on the inside front cover.BS1660-11:1991 BSI 07-1999 1 1 Scope This Part of BS 1660 specifies gauges for the manufacture and verification
16、of the accuracy of self-holding and self-release tapers given in other Parts of BS 1660. 2 Gauges NOTETypes of gauges and their uses are described in Appendix A and illustrated in Figure 1 to Figure 8. 2.1 Dimensions The dimensions and tolerances of plug gauges shall be as given in Table 1 to Table
17、9, as appropriate. The dimensions and tolerances of ring gauges shall be as given in Table 10 to Table 12, as appropriate. 2.2 Material The gauges shall be made of steel, hardened and stabilized, and the working surfaces shall have a diamond pyramid hardness number between 750 and 850. NOTE 1Tool st
18、eels of grade 01 are suitable. NOTE 2The following method is recommended as a suitable stabilizing process. Before final grinding, heat the hardened gauges to, and maintain at, a temperature of 150 C for 5 h then allow to cool slowly in the furnace. 2.3 Workmanship Gauging or working surfaces shall
19、be ground or lapped. Knurled surfaces shall not be so sharp as to injure the hands when the gauge is used continuously. Centres of plug gauges shall not be removed and shall be protected from damage by a small recess where practicable. 2.4 Gauge wear and wear allowance A working plug gauge shall be
20、permitted to wear by the following values below the lower limit of dimension D or D 1given in Table 1 to Table 9, as appropriate. A working ring gauge shall be permitted to wear by the following values above the upper limit of dimension D or D 1given in Table 10 to Table 12, as appropriate. Gauges o
21、utside the given wear allowances shall not be used for inspecting finished work. NOTEGauge users should watch for the effect of wear upon sizes of their gauges. Regular examination and measurement of gauges in use is essential so that a gauge which has worn outside its wear allowance is detected and
22、 withdrawn from service. 2.5 Tommy bar hole One 15 mm diameter tommy bar hole shall be provided in all 40 mm diameter plug gauge handles at a centre distance of 25 mm from the free end of the handle for both lifting purposes and for turning when inserted in a bore. 3 Marking Gauges shall be permanen
23、tly and legibly marked with the following information: a) the size and type; b) the number and date of this British Standard, i.e. BS 1660-11:1991 1) ; c) the makers name and/or trade mark. NOTE 1Gauges intended for use as reference gauges should bear in addition a serial number and should be marked
24、 “For reference only”, or “REF”. NOTE 2It is desirable that all gauges should bear a serial number; such a number is usually required if the gauge is to be submitted to an inspecting authority for certification.
