BS EN ISO 7625:2012

This standard BS EN ISO 7625:2012 Sintered metal materials, excluding hardmetals. Preparation of samples for chemical analysis for determination of carbon content is classified in these ICS categories:

• 77.160 Powder metallurgy

This International Standard specifies methods for preparing a sample from one or more sintered parts to be analysed for free or total carbon content. Combined carbon is determined as the difference between total and free carbon. This standard covers the preparation of samples for the determination of carbon by a chemical method, i.e. combustion in oxygen and measurement of the carbon dioxide produced, in accordance with ISO 437. It does not cover the preparation of samples for carbon determination by physical methods, such as metallography or spectroscopy.
