Caustic burned magnesia for magnesium oxychloride cement products 1 Scope This standard specifies the grading, requirements, test methods, inspection rules, packaging, marking, transportation and storage of the caustic burned magnesia for magnesium oxychloride cement products. This standard is applicable to caustic burned magnesia made from magnesite (MgCO3) by calcination and grinding for oxychloride cement products. 2 Normative references The following normative documents contain provisions which, through reference in this text, constitute provisions of this standard. For dated references, subsequent amendments (excluding corrections) to, or revisions of, any of these publications do not apply to this standard. However, parties to agreements based on this standard are encouraged to investigate the possibility of applying the most recent editions of the normative documents indicated below. For undated references, the latest edition of the referenced document applies.
