This document provides specific technical guidance for the production of pure metals or their corresponding crystalline salt certified reference materials (CRMs) in accordance with the general requirements of ISO 17034. In this document, reference to a CRM is limited to solid pure metal and crystalline salt certified reference materials, including candidate materials, unless otherwise noted.

The method is applicable to carbon contents between 0,003% (m/m) and 4,5 % (m/m). Specifies principle, reagents, apparatus, sampling, procedure, expression of results and test report. The annexes give additional information on the international co-operative tests, a graphical representation of precision data and features of induction furnaces and carbon analysers.

This document specifies the requirement for testing of special properties of hot-rolled steel sheet piles.

This document specifies a gravimetric method for the determination of the loss on ignition (LOI) in solid rare earth oxides, carbonates and oxalates. This document is applicable to the determination of the LOI in the range from 0,10 % to 15,00 % in rare earth oxides, from 25,00 % to 80,00 % in rare earth carbonates, and from 35,00 % to 75,00 % in rare earth oxalates.

This International Standard specifies ways in which rare earths can be traced as they move through the supply chain between the separated products to rare earth permanent magnets, or otherwise further processed. This standard complements ISO 23664.

The documented traceability information will assist purchasers, suppliers, and users of rare earth permanent magnets to identify parties in the supply chain who have processed a given shipment of rare earth material, the location of that rare earth material as it passes between supply chain nodes. Supply chain actors and end users can use this information to check the validity of any claims made on the rare earth permanent magnets concerning sustainability, environmental impact, or recycled material content.

The document specifies a gravimetric method for the determination of the moisture content in rare earth solid concentrate, rare earth oxides and rare earth fluorides.
