The SRM 2696 Silica Fume will help to minimize erroneous testing, simplifying the test process through standardization and provide the user/specifier reliable data. Certified values have been established for SiO2 and six other chemical constituents plus reference values for five chemical constituents and the physical measurement parameter Specific Surface Area. All values are a product of extensive testing by National Institute of Standards and Technology (NIST) and collaborating laboratories from state departments of transportation, universities, commercial testing laboratories, distributors and manufacturers. Each unit of SRM 2696 consists of a single, sealed bottle of approximately 70 grams of powder supplied with a Certificate of Analysis and a Material Safety Data Sheet (MSDS). SRM 2696 can be ordered directly from NIST through their secure online SRM Order Request System at http://ts.nist.gov/measurementservices/referencematerials/index.cfm.
