STANDARD REFERENCE MATERIALS

*New in FY-1995

The Division provides science, industries, and government a central course of well characterized materials certified for chemical composition of physical or chemical properties. These materials are issued with a certification and are used to calibrate instruments, to evaluate analytical methods, or to produce scientific data which can be referred to a common base.
