SPECTRUM QUALITY STANDARDS Daily Check Standards for D4815 and/or D5599
The EPA requires calibrations be checked using a Calibration Check Standard at least once per analysis batch or once per 10 samples; and an Independent Reference Standard at least once per analysis batch or at least once per 100 samples. Additionally, the Calibration Check Standard and the Reference Standard must be made from different lots of raw materials and by different persons. Spectrum manufactures Check Standards in compliance with EPA regulations. They consist of a Calibration Check Standard, a Reference Standard, and a Reference Blank.
