6、cifications (GPS)” has been added to the title. b) “R setting rings” for adjustable reamers are now specified. c) Subclause “Requirements for R setting rings” has been added. d) The tolerance class for bore d1for C setting rings has been changed from “JS3” to “JS4”. e) The run-out tolerance has been
7、 replaced by the squareness tolerance. f) The roughness parameter “Rz” has been changed to “Rzmax” in accordance with DIN EN ISO 1302. g) The standard has been editorially revised.
