This document specifies a point counting method for statistically estimating the volume fraction of a constituent through the microstructure of a steel by means of a point grid. It applies to constituents which are clearly identifiable. By default, counting is performed manually, but can be computer assisted or substituted by validated computer algorithms. NOTE            In this document, the…

This document specifies two methods for determining the adhesion strength of vulcanized rubber to wire cord which is embedded in the rubber. The two methods do not necessarily give the same results. They are applicable primarily to test pieces prepared in the laboratory under standard conditions and used for the development and control of materials and processes utilized in the manufacture of…
