Troemner OIML Precision Weights conform to the standards of the Organisation Internationale de Metrologie Legale International Recommendation (OIML R 111). They are manufactured from the finest stainless steels available including Troemner Alloy 8 Stainless Steel that has low magnetic permeability, uniform consistency and high resistance to corrosion. Troemner OIML Precision Weights are available in Classes E1, E2, F1 and F2, where Class E1 has the smallest tolerances and Class F2 has the largest tolerances. The letter "E" for Classes E1 and E2 refers to "extra fine" where the letter "F" for Classes F1 and F2 refers to "fine". OIML R 111 weight specifications are designed so the specifications on surface finish, markings, construction, material density and magnetic properties get more restrictive as the weight tolerances get smaller in order to enable the weight to maintain its tolerance over time. The tolerances for the various classes are established in a manner that enables weights of higher classes to calibrate weights of the next lowest class. For example, Class E2 weights can be used to calibrate Class F1 weights. Troemner OIML Precision Weights and Weight Sets are supplied with Troemner's Statement of Accuracy, which details the date of calibration and accuracy class of each weight. If your laboratory requires more stringent documentation, please review the Weight Calibration and Certificate Options section of the website.
**Caution** Class E1 weights have extremely small tolerances and are intended to be used as primary reference standards with direct traceability to national reference standards. They should be used in extremely stable environments and handled with the highest level of care. Otherwise, Class E1 weights will not maintain their measured value within the tolerance class. One may be tempted to purchase the weights with the tightest tolerances in order to reduce measurement uncertainty. However, frequency of use, care, handling, and environmental conditions all play a major role in long term stability of weights and these factors should be considered before purchasing Class E1 weights.
Class F1 weights can be used to calibrate certain Class I balances and scales as specified in OIML R 76. Class F1 weights can also be used to calibrate Class F2 weights.
