Replaces JB/T7976--95wwW.bzxz.Net
2.1 Profile method of measurement of the surface roughness A method for evaluating surface roughness based on profile parameters measured on the surface. 2.2 Instrument for the measurement of surface roughness by the profile method
An instrument that measures the surface roughness parameters by the profile measured on the surface. 2.3 Contact (stylus) instrument of consecutive transformation of a profile
An instrument that measures the surface roughness by the method of sequential transformation of profile information during the mechanical movement of the stylus along the measured surface. Note
1 The movement of the stylus may be continuous or intermittent. 2 The stylus of the instrument has a specified geometric shape and is used to describe the profile during the information transformation process. 2.4 Contactless instrument of consecutive profile transformation An instrument that measures the surface roughness by the method of sequential transformation of profile information without any mechanical contact with the measured surface.
2.5 Contact instrument of instantaneous profile transformation An instrument that measures the surface roughness by the method of instantaneous transformation of profile information during the mechanical contact with the measured surface. 2.6 Non-contact instrument of instantaneous profile transformation An instrument that measures surface roughness by instantaneous profile transformation without any mechanical contact with the measured surface.
Approved by the State Machinery Industry Bureau on May 20, 1999, and implemented on January 1, 2000
