NATIONAL FOREWORD
This Indian Standard ( First Revision ) which is identical with IS0 2407 - 1984 ‘Acceptance
conditions for internal cylinderical grinding machines with horizontal spindle - Testing of
accuracy’ issued by the International Organization for Standardization (ISO), has been adopted
bythe Bureau of Indian Standards on the recommendations of the Machine Tool Basics and
Modular Units Sectional Committee ( PE 03 ) and approved by the Production Engineering
Division Council.
This standard was first issued in 1982 based on IS0 2407 : 1973. Consequent upon the revision
of the IS0 standard, this standard has been revised by adopting IS0 2407 : 1984, to bring it in
line with IS0 standard.
Certain conventions are, however, not identical to those used in Indian standards. Attention is
particularly drawn to the following:
a) Wherever the words ‘International Standard’ appear referring to this standard, they
should be read as ‘Indian Standard’.
b) Comma ( , ) has been used as a decimal marker in the International Standards while in
Indian Standards the current practice is to use point ( . 1 as the decimal marker.
c) Some dimensions appear in ‘inches’ in the International Standard besides in metric
systems while in Indian Standards, the current practice is to give metric values only.
In this adopted standard, reference appears to ISO/R 230 ( since revised as IS0 230/l : 1986 ).
The Indian Standard IS 2063 : 1988 ‘Acceptance code for machine tools : Geometric accuracy
of machines operating under no load or finishing conditions ( first revision ) which is identical
with IS0 230/l : 1986 is to be substituted in its place.
