OREAS 713 is a primary CRM prepared from gravity-separated fractions of the Westland Heavy Mineral Sands deposit. The material contains elevated levels of TiO₂, Fe, and Zr and represents a composite of high and concentrate-grade heavy mineral sands. It is designed for use in the validation and quality control of methods targeting titanium-, iron-, and zirconium-bearing minerals in sediment-hosted mineral sands systems.
OREAS 713 has been characterized using the following methods:
Certified values for applicable analytes are operationally defined for each method, with results under OREAS ISO 17034 scope of accreditation.
