标准物质是已确定其中一种或几种特性量值,用于校准测量器具,评价测量方法或确定材料特性量值的物质,是依法管理的一种计量器具。作为现代计量学研究中的一个重要分支,也是量值传递及溯源的一种重要手段,标准物质广泛地用于需要对物质的成分或特性进行测量的一切工作中,或校准仪器、或评价测量方法,其目的在于保证测量过程和测量结果的准确一致。无论是冶金、化工等
Reference material has been identified one or more of the characteristic values, used to calibrate measuring instruments, measuring methods or to determine the value of material properties of substances, is a kind of measuring instruments administered by law. As an important branch of modern metrology research, it is also an important measure of mass transfer and traceability. Standard materials are widely used in all the work that needs to measure the composition or characteristics of materials, or calibrate instruments or measure and measure Method, the purpose is to ensure accurate and consistent measurement process and measurement results. Whether it is metallurgy, chemical industry
