Introduction,program to provide reference materials, originally known as standard samples, largely in response to the needs of the metal industry. The reliability of all analytical results is completely dependent on the availability of reference materials and nowadays nearly all branches of analytical chemistry declare an urgent need for reference materials.寡头政治 发表于 2025-3-27 03:04:11
Book 2000er protection, sports and jurisdiction. In all spheres, analytical results need to fulfill a purpose. This means being accurate to a specified extent according to the required level of uncertainty, as well as being comparable, depending on the range of validity. In many cases, this range is global.cliche 发表于 2025-3-27 06:03:13

Reference Materials in Materials Testing,e materialized through strict implementation of quality assurance systems. To achieve a high quality of products, reliable and accurate measurement is needed. The required quality can only be achieved or confirmed through the use of reference materials prepared and certified to a high level.违法事实 发表于 2025-3-27 19:53:27
