BS 4361-6:1988

Accuracy, geometrical tests and terminology.

This International Standard specifies the terminology appropriate to each part of the machine and, with reference to ISO/R 230, the geometrical test for single spindle moulding 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 ISO languages (English and French), this International Standard gives in the annex the equivalent terms in German, Spanish, Italian and Swedish; these have been included at the request of ISO Technical Committee TC 39 and are published under the responsibility of the member bodies for Germany, F.R. (DIN), Spain (IRANOR), Italy (UNI) and Sweden (SIS). However, only the terms and definitions given in the official languages can be considered as ISO 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.) which should generally be checked before testing accuracy.

This International Standard does not impose any practical test for single spindle moulding machines. Practical tests should be exceptions and have to be stated in a previous agreement between the producer and the user.
