LAC 33:I.5305. Calibration

A. Measuring and testing equipment used by the testing laboratory shall be calibrated, where appropriate, before being put into service and thereafter according to an established program. B. The overall program of calibration of equipment shall be designed and operated so as to ensure that measurements made in the testing laboratory are traceable (where the concept is applicable) to national standards of measurement and, where available, to international standards of measurement specified by the International Committee of Weights and Measures. Where the concept of traceability to national or international standards of measurement is not applicable, the testing laboratory shall provide satisfactory evidence of correlation or accuracy of test results (e.g., by participation in a suitable program of interlaboratory comparisons). C. The laboratory shall record all calibration data including frequency, conditions, and standards used for all analytical methodology. D. The laboratory shall verify and document all standards versus primary (reference) standards.
