This standard was first issued in 1966 and subsequently revised in 1976.- Consequent upon the publication of IS0 7987 : 1985, this standard has been revised by adopting IS0 7987 : 1985 to bring it in line with IS0 standard. In this revision, clause references of IS0 230/t : 1986 for method of tests has been incorporated which were not there earlier. The text of ISO’ standard has been approved as suitable for publication as Indian Standard without deviations. 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 Jlndian Standard’. b) Comma ( , ) has been used as a decimal marker while in Indian Standards, the current practice is to use a point ( . ) as the decimal marker. In this adopted standard, reference appears to lSO/R 230 ‘Test code for machine tools’ ( since revised as IS0 230/l : 1986 ). .T he Indian Standard IS 2063 : 1988 ‘Acceptance code for machine tools - Geometric accuracy of m a chines operating under no load or finishing conditions ( first revision )’ which is identical with IS0 230/l : 1988 is to be substituted in its place. Only the English language text,of the International Standard has been retained while adopting it as Indian Standard.

The measuring instruments shall not permit errors over l/3 of the checked tolerances. 3.3 The sequence in which the geometrical tests are given is related to the sub-assemblies of the machine and this in no way defines the practical order of testing. In order to make mount- ing of instruments or gauging easier, tests may be applied in any order. This International Standard deals only with the verification of accuracy of the machine.
