All Denver Instrument calibration weights meet or exceed ASTM specifications All mass measurements are made using procedures developed by NIST All mass standards are milled from the finest bar steel stock ensuring consistent density Each weight calibration is performed in a climate-controlled environment Ideally, the standard has less than 1/4 of the measurement uncertainty of the device being calibrated. All the weights taken should be ± 10% of the target weight as specified in the individual monograph. Posted January 16, 2020 by Kevin Hill & filed under analytical balances.. ISO/IEC 17025 is useful for any organization that performs testing, sampling or calibration and wants reliable results. In ordinary use, however, most people include the verification step in the standard process of calibration or recalibration. Contents specific to glassware calibrations have been included in SOP 14. A company that pays $2,000 to have an ultrasonic flowmeter recalibrated is most likely not going to be satisfied with a report that says, "We have tested your flowmeter against an approved standard and found that it is not reading properly." Weights that are calibrated to standard procedures do not have this factor taken into account because the air buoyancy affects both sides of the mass balance and can be ignored. This includes all types of laboratories, whether they be owned and operated by government, industry or, in fact, any other organization. All calibrations are accredited calibrations performed using weights by NIST weighing designs, where all weights are compared against 2 standards. Calibration weights (also known as reference weights or test weights) are known, standard weights, manufactured to very high tolerances and accuracy, used for the performance checking and calibration of analytical balances, precision balances and general-purpose scales in the research laboratory, educational settings and other working environments.
