TEST CHART FOR WOODWORKING SLOT MORTISING MACHINES
( First Revision )
NATIONAL FOREWORD 8
This Indian Standard ( First Revision ) which is identical with IS0 7946 : 1985 ‘Woodworking machines - Slot mortising machines - Nomenclature and acceptance conditions’ issued bythe International Organization for Standardization ( IS0 ), was adopted by the Bureau of Indian Standards on the recommendations of Woodworking Machines Sectional Committee ( PE 01 ) and approval of Production Engineering Division Council.
This standard was first issued in 1974. Consequent upon the publication of IS0 7946 : 1985, this standard has been revised by adopting IS0 7946 : 1985 to bring it in line with IS0 standard. In this revision, clause references of IS0 230 - 1 : 1986 for method of tests has been incorporated which were not there earlier.
The text of IS0 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 ‘Indian Standard’.
b) Comma (, ) has been used as a decimal marker while in Indian Standards, the current prac- tice 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 - 1 : 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 - 1 : 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.

1 Scope and field of application
This International Standard specifies the nomenclature ap-
propriate to each part of the machine and, with reference to
ISO/R 230, the geometrical tests for slot mortising machines,
and gives the corresponding permissible deviations which apply
to machines for general purpose use and normal accuracy.
NOTE - In addition to terms used in two of the three official IS0
languages (English and Frencht, this International Standard gives in
the annex the equivalent terms in German, Spanish, Italian and
Swedish; these have been included at the request of Technical Com-
mittee ISO/TC 39 and are published under the responsibility of the
member bodies for Germany, F.R. (DIN), Spain (IRANOR), Italy (UN11
and Sweden (SIS). However, only the terms and definitions given in
the official languages can be considered as IS0 terms and definitions.
This International Standard deals only with the verification of
accuracy of the machine. It does not apply to the testing of the
running of the machine (vibrations, abnormal noises, stick-slip
motion of the components, etc.), nor to its characteristics
(speeds, feeds, etc. 1 which should generally be checked before
testing accuracy.
This International Standard does not impose any practical test.
For slot mortising machines, practical tests should be
exceptions and have to be stated in a previous agreement be-
tween the producer and the user.

60/R 230, Test code for machine tools.
3 Preliminary remarks
3.1 In this International Standard all dimensions and permiss-
ible deviations are expressed in millimetres.
3.2 To apply this International Standard, reference should be
made to ISO/R 230, especially for installation of the machine
before testing, the warming up of the main spindle and other
moving parts, and description of measuring methods. 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.
3.4 When inspecting a machine, it is not always possible or
necessary to carry out all the tests given in this International
Standard.
3.5 It is up to the user to choose, in agreement with the
manufacturer, those tests relating to the properties which are
of interest to him, but these tests are to be clearly stated when
ordering a machine.
3.6 A movement is longitudinal when it takes place in the
working direction of the piece.
3.7 When establishing the tolerance for a measuring range
different from that given in this International Standard, (see
2.311 in ISO/R 230), it should be taken into consideration that
the minimum value of the t<olerance is 0,Ol mm.
