ISO 11459:1997 Iron ores — Certified reference materials — Preparation and certification for use in chemical analysis

Annotation Preview

This International Standard is intended for use in conjunction with other International Standards for the chemical analysis of iron ores prepared by ISO/TC 102. It follows the principles described in ISO Guides 30, 31, 33 and 35 (see clause 2 and annex D) on the same subject prepared by ISO/REMCO, modified to take into account the special needs of the iron ore analytical community. The accuracy (precision and trueness) of International Standard methods for the chemical analysis of iron ore has been assessed under international conditions during the development of this International Standard. This accuracy can be achieved, in practice, only if all conditions stated in the standard document are met. To ensure that these conditions are met, an accuracy control mechanism is included in all recently published International Standards for the chemical analysis of iron ores.
