一、 “七五”标准制修订计划根据1987年4月公布的机械电子工业部“七五”期间标准制、修订计划(仪器仪表材料部分),1987至1990年仪表材料行业(不包括光学玻璃、特种玻璃、永磁材料、张丝和电接点材料等类)计划制、修订国家标准和专业标准23项, 1986年由“六五”结转3项。整个“七五”期间计划制、修订国家标准和专业标准共26项(见表1)。在实施过程中因条件不成熟和冶金部已制定了国标等原因,撤消高温应变电阻合金丝和仪表用金属材料盐雾腐蚀试验方法等4项,因此,实际计划制、修订国家标准和专业标准22项。
First, the “seven five ” standard system revision plan According to the 1987 Ministry of Machinery and Electronic Industry released “” during the standard system, the revision plan (instrumentation materials section), 1987 to 1990 instrumentation materials industry ( Excluding optical glass, special glass, permanent magnetic materials, wire and electrical contact materials and other categories) planning system, revision of 23 national standards and professional standards in 1986 by the “65” carried three. The whole “seven five ” plan during the revision of national standards and professional standards a total of 26 (see Table 1). In the implementation process due to the immature conditions and the Ministry of Metallurgical has developed a national standard and other reasons, the withdrawal of high temperature strain resistance alloy wire and instrument metal materials salt spray corrosion test method 4, so the actual planning system, the revision of national standards and professional standards 22 items.
