1 The measure of accuracy for control of inspection, measuring and test equipment

2 Know-how for reliable weighing results all down the line The complete line from weights to certified testing services Regular inspection and testing of weighing instruments are a must to ensure reliable weighing results. As a leading manufacturer of precision weighing instruments, analytical balances and industrial scales worldwide, Sartorius will provide you with all the equipment and services that you need for testing and monitoring your weighing instruments. For inspection and testing, Sartorius offers highly accurate metrological weights and weight sets with nominal s from mg to,000 kg, special and test weights, as well as the accessories required for correct handling and storage of weights. Sartorius weights and weight sets are available in standard versions, are calibrated by the DKD* and comply with the International Recommendation, OIML-R. Therefore, they are suitable for legal and general metrological applications in research and industry. Sartorius weights meet the requirements for traceability to the national kilogram prototype in conformance with the International Standard ISO 9000 concerning the quality element Inspection, measuring and test equipment. These weights help support your quality management and quality assurance systems, and fulfill GLP and GMP requirements. Your DKD partner for mass units Sartorius has DKD laboratories for both weights and electronic laboratory balances and industrial scales. Sartorius calibration laboratories have been inspected and accredited for compliance with the regulations of the German calibration service, DKD, concerning mass units. These laboratories meet the international standard for testing laboratories, ISO IEC 7025, which has been adopted as a European Standard under EN ISO IEC Recalibration for any brand names, manufacturers and designs Depending on how frequently weights are used, they must be recalibrated on a regular basis so that they will meet the requirements for reliable measuring, inspection and test equipment. Sartorius offers recalibration service along with DKD calibration certificates for all weights ranging from mg to kg, regardless of their design or brand name. * DKD = German Calibration Service; DKD certificates are officially recognized in all countries that belong to the Western European Calibration Cooperation (WECC), such as Denmark, Finland, France, Great Britain, Italy, the Netherlands, Sweden and Switzerland 2

3 Here s how to find the right test weight Just determine the number of digits specified for your weighing instrument s resolution, then read off the particular accuracy class that your test weight must have on the graph provided on the right. Digits,000,000,000 n = max : d n = resolution of your weighing instrument (digits) max = maximum weighing capacity of your instrument d = readability of your weighing instrument The weight value of your test weight should be more than 80% of the maximum capacity of your weighing instrument. 00,000,000 Use the chart on right to determine whether you need an individual weight or a weight set by comparing the nominal s. Example: Suppose your weighing instrument has a capacity of 2, g and a readability of 0.0 g. This yields 220,000 digits, which correspond to a class E2 test weight. Since 80% of 2, g is,760 g, you need to round it to a weight value of 2 kg according to the chart. 0,000 5,000 M * or E2, DKD-calibrated F2 F E2 E* Maximum permissible errors according to OIML Recommendation R +/ in mg class Nominal E E2 F F2 M M2 M3 mg mg mg mg mg mg mg mg mg / mg g g g g g g g g g kg kg ,000 5 kg ,5 0 0kg ,5 05, 0 20 kg ,000 3,000 0,000 kg , 7, 25,000 Maximum permissible errors of the high-capacity weights correspond to extrapolated OIML classes F M 00 kg, 5,000 kg,000 3,000 0,000 kg 2, 7, 25,000,000 kg 5,000 5,000,000 All weights have been adjusted to the reference density of 8.0 g/cm 3 at an air density of.2 kg/m 3. 3

4 Sartorius weight sets Metrological weight sets in a wooden case with forceps* The Sartorius line of weight sets includes sets of reference or test standards supplied in highquality cases and service weight sets that come in a practical carrying case for maintenance of balances and scales when you re on the move. Weight set in wooden case Service case Knob weights Leaf weights Sartorius sets contain knob weights for nominal s from g and upward. Sets with weights ranging from mg to mg can be supplied in your choice of easy-to-handle leaf weights made of aluminum or nickel silver, or wire weights made of special, wear-resistant stainless steel.

You can request E recalibration as a special service from Sartorius. Recalibration entails issuing a calibration certificate that indicates the nominal, the actual value measured, and the uncertainty of the measurement of the weight. For recalibration, we need to know the accuracy you require (uncertainty, accuracy class) and your exact mailing address. To ensure prompt and efficient processing of your recalibration order, please state the complete order number of the weight(s) on your order. Suministros LPS S. de R.L. de C.V. Av.
