This standard specifies the requirements, test methods, inspection rules and signs, packaging, transportation, storage, quality certificates and contracts (or purchase orders) for antimony ingots. This standard applies to antimony ingots produced from antimony concentrates and lead-antimony concentrates, and antimony beads produced from antimony concentrates and lead-antimony concentrates can also refer to this standard.
