0. FOREWORD
0.1 This Indian Standard ( Part 3 ) ( Second Revision ) was adopted by the Indian Standards Institution on 10 September 1984, after the draft finalized by the Textile Mill Accessories (Other Than Jute) Sectional Committee had been approved by the Textile Division Council.
0.2 The recommended dimensions of tubes are based on IS0 368-1982 Tubes for ring spinning, doubling and twisting spindles with taper 1: 38 and 1 :64 issued by the International Organization for Standardization ( IS0 ).
0.3 Other requirements such as type, material, finish, concentricity, water absorption and steam conditioning are specified in Part 1 of the standard.
0.4 For the purpose of deciding whether a particular requirement of this standard is complied with, the final value, observed or calculated, express- ing the result of a test, shall be rounded off in accordance with IS : 2-1960*. The number of significant places retained in the rounded off value should be the same as that of the specified value in this standard.
1. SCOPE
1.1 This standard recommends dimensions ( length and inside diameter ) of tubes with taper 1: 64 for ring spinning and doubling spindles.
*Rules for rounding off numerrcal values ( revised ).
3
IS : 3625 ( Part 3 ) - 1984
1.2 It also specifies the dimensions and tolerances for the gauges for checking the tubes.
2. DIMENSIONS
2.1 The recommended dimensions are given in Table I read with Fig. IA and Fig. 1B.
3. DIMENSIONS FOR GAUGES
3.1 The dimensions and tolerances of gauges for tubes of Types A and B are given in Tables 2 and 3 read with Fig. 2A and Fig. 2B respectively.
