0. FOREWORD

0.1 This Indian Standard ( First Revision ) was adopted by the Bureau of Indian Standards on 6 July 1987, after the draft finalized by the Spinning Machinery ( Cotton System ) Sectional Committee had been approved by the Textile Division Council.

0.2 This standard, originally published in 1972, has been revised to align dimensions, thickness and gauge number with IS0 2572-1982 ‘Textile machinery and accessories - Card gauges’ issued by the Inter- national Organization for Standardization ( IS0 ).

~0.3 For the purpose of deciding whether a particular requirement of this standard is complied with, the final value, observed or calculated, expres- sing 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 prescribes the requirements for two types of card gauges currently used to set the distance between the working elements of cards.

2. MATERIAL

2.1 The gauges shall be made from suitable materia1 so as to attain hardness of 55 to 60 HRC.

3. WORKMANSHIP AND FINISH

c

3.1 The gauges shall have smooth scratch-resistant surface with ground and lapped finish. The gauges shall be flexible.

*Rules for rounding off numerical values ( revised ) .
