7 IS:689( Part;)1988 EXPLANATORY NOTE The proforma for preparation of purchase specification for machine tools has been prepared to enable a prospective buyer to collect data from various manufacturers/suppliers for the purposes of comparison. This proforma is meant to be sent out with an enquiry by the purchaser so that the manufacturers/suppliers can fill in the data and send it back to the purchaser to make the comparison easier for the purchaser. Reference is made to the following Indian Standards in this proforma: IS : Colours for ready mixed paints ( third revision ) IS : Dimensions for self holding tapers ( second revision ) IS : Dimensions for Tslots ( second revision ) i IS : Specifications for coolant pumps for machine tools IS : 199l 96 Test chart for radial drilling machines IS : Spacing for Tslots ( second revision ) IS : Degrees of protection provided by enclosures for rotating machinery IS : Measurement and evaluation of vibration of rotating electric machines IS : Principles of mechanical guarding of machinery IS : 10988I 98 Method of measurement of noise from machine tools This standard was first published in 197. The coittee responsible for the formulation of this standard decided to revise the sane based upon the experience gained. In the present revision, detailed requirements of motors and coolant pumps requirements for environmental and safety aspects have also been included in the proforma.
