1989年国家标准局颁布执行新的国家标准GB8733—88铸造铝合金锭,各牌号铸铝化学成分的元素含量范围要求都有很大的变化,并增加了很多杂质元素量要求。这就要求尽快研制适应上述标准的高质量的标准样品。 我们依照上述标准元素配置和含量范围最新设计了四批新的铸铝标样,运用先进的研制工艺,制定严格的技术条件,保证了样品均匀性良好。采用国家标准或权威可靠的分析方法定值及对各项技术指标的检查,定值结果准确可靠,分析曲线线性关系良好。经与国内外同类标样对比,从成分设计、均匀性到线性关系,均优于对比标样。
1989 National Bureau of Standards promulgated the implementation of the new national standard GB8733-88 cast aluminum ingots, the various grades of the chemical composition of the elemental content of aluminum have a great range of requirements, and added a lot of impurity element requirements. This requires the development as soon as possible to adapt to the above criteria of high quality standard samples. In accordance with the above-mentioned standard elements configuration and content range of the latest design of the four groups of new cast aluminum standard, the use of advanced technology, develop strict technical conditions to ensure a good sample uniformity. Using national standards or authoritative and reliable analytical method of value and the inspection of the technical indicators, the value of accurate and reliable results, the analysis of the linear relationship between the good. Comparing with similar standards at home and abroad, from the composition design, uniformity to linear relationship, are better than the standard comparison.
