BS EN ISO 4499-2:2020 PDF

Scope: What is ISO 4499 ‑ 2 about? ISO 4499 ‑ 2 is the second part of a series of documents on hard metals. ISO 4499 ‑ 2 gives guidelines for the measurement of hard metal grain size by metallographic techniques only using optical or electron microscopy. It is intended for WC/Co hard metals (also called cemented carbides or cermets) containing primarily tungsten carbide (WC1)) as the hard phase. It is also intended for measuring the grain size and distribution by the linear-intercept technique. ISO 4499 ‑ 2 essentially covers four main topics: Calibration of microscopes, to underpin the accuracy of measurements; Linear analysis techniques, to acquire sufficient statistically meaningful data; Analysis methods, to calculate representative average values; Reporting, to comply with modern quality requirements. ISO 4499 ‑ 2 is supported by a measurement case study to illustrate the recommended techniques (see Annex A). ISO 4499 ‑ 2
