ISO Releases New Standard on Gears - Surface temper etch inspection after grinding, chemical method

      ISO/TC 60 Working Group 14, responsible for standards dealing with metallurgy and materials, has just published ISO 14104:2014 “Gears — Surface temper etch inspection after grinding, chemical method”.

A system to describe and classify the indications produced during this inspection is included. However, specific acceptance or rejection criteria are not contained.

      The new standard supersedes the previous version, ISO 14104:1995.
