The Ohaus metric, stainless steel electronic balance calibration weight meets American Society for Testing and Materials (ASTM) Class 4 specifications, and is designed for use as a reference standard for calibrating other weights, or electronic balances and scales. The weight has straight sides and a flat top that allows weights to be stacked. It is constructed of stainless steel for stability, resistance to corrosion, and low magnetic susceptibility. The weight meets ASTM E617, Class 4 specification for use as a reference standard for calibrating semi-analytic balances, and for student use. An optional National Voluntary Laboratory Accreditation Program (NVLAP) certificate ensures precision and traceability. The National Voluntary Laboratory Accreditation Program (NVLAP) accredits laboratories for compliance with ISO/IEC 17025 on the basis of their ability to meet the technical requirements set forth in NIST Handbook 150-2, and can provide accreditation to ANSI/NCSL Z540-1-1994. NVLAP calibrations and certifications meet all ISO, FDA, GMP, GLP, DOD, ANSI/NCSL Z540-1 and Nuclear requirements and are traceable to NIST. Procedures and processes used to generate this multi-page certificate, as well as its format and content, are prescribed by NVLAP. The document contains customer name & address, date of calibration, equipment and standards used in the calibration, accuracy class, true mass value (mass in a vacuum), “As Found†mass correction (for recalibration), “As Left†mass correction, uncertainty of measurement process (uncertainty to tolerance ratios are guaranteed), environmental conditions during test, construction and density of the weight, calibration procedure, and a statement of traceability to NIST. Mutual recognition arrangements include The International Laboratory Accreditation Cooperation (ILAC), The Asia Pacific Laboratory Accreditation Cooperation (APLAC) and The National Cooperation for Laboratory Accreditation (NACLA). Calibration weights are used to measure the weight or...
