包头铝厂研制的稀土铝合金光谱标样,最近在包头铝厂通过技术鉴定。鉴定委员会一致认为:该套标样具有均匀性和线性关系好,定值可靠,符合DB-86标准的要求,并认为包头铝厂可作为该标样批量生产单位。这套标样为五点式的φ38×45(mm)的圆柱体和φ10×150(mm)的棒状光谱标样,化 Baotou Aluminum Rare Earth Aluminum Alloy developed spectral standard samples, recently in Baotou aluminum through technical appraisal. Accreditation Committee agreed that: The standard set of uniform and linear relationship is good, reliable, in line with the requirements of DB-86 standards and that Baotou Aluminum can be used as the standard mass production units. This set of standards for the five-point φ38 × 45 (mm) of the cylinder and φ10 × 150 (mm) of the rod spectrophotometer standardization
