在HG1—552—67“磷精矿和磷矿石统一分析方法”的基础上,经湖南化工研究所、参加起草单位及化学矿标准化专业技术归口单位的共同努力,通过近二年的试验,验证,完成了国家标准草案送审稿。1979年12月2日至6日在湖南省长沙市召开了“磷精矿和磷矿石分析方法”国家标准审查会。参加会议的有科研、磷矿、磷肥厂、大专院校及地质部门等32个单位代表共51人。受化工部科技局委托,会议由化学矿标准化专业技术归口单位——化工部化工矿山设计研究院主持。化工部科技局和化学矿山局均派代表到会指导。
On the basis of HG1-552-67 “unified analysis method of phosphate concentrate and phosphate rock”, with the joint efforts of Hunan Chemical Industry Research Institute, participating drafting units and standardization specialized technical focal points for chemical minerals, through nearly two years of experiments, Verification, completed the draft standard draft for review. December 1979 December 2 to 6 in Changsha, Hunan Province held a “phosphorus concentrate and phosphate rock analysis method” review of national standards. A total of 51 representatives from 32 institutes including scientific research, phosphate rock, phosphate fertilizer plant, universities and geological departments participated in the conference. Commissioned by the Bureau of Science and Technology Ministry of Chemical Industry, the meeting was hosted by the Ministry of Chemical Industry Mining Design and Research Institute of Chemical Minerals standardized professional and technical units. Chemical Technology Bureau and the Bureau of Chemical Mine were sent representatives to guide.
