FOREWORD
This Indian Standard which is identical with IS0 11675 : 1994 ‘Textile machinery - Flatbed knitting
machines - Vocabulary’ issued by the International Organization for Standardization
(ISO), was
adopted by the Bureau of Indian Standards on the recommendation
of the Machinery for Fabric
Manufacture Sectional Committee and approval of the Textile Division Council.
The text of IS0 standard has been approved as suitable for publication as Indian Standard without
deviations. Certain conventions
are, however, not identical with those used in Indian Standards.
Attention is particularly drawn to the following:

Standard’ appear referring to this standard, they should be
b)
Comma (,) has been used as a decimal marker% the International Standard, while in Indian
Standards, the current practice is to use a point (.) as a decimal marker.
