HÄFNER standard weights Weights of classes E0, E1, E2
The intended purpose of the mass standards and standard weights E0, E1 and E2 is as adjustment, testing and calibration instruments (tracing) for high precision weighing or comparative measurements and for quality assurance in accordance with DIN EN ISO 9001ff.
Mass standards - class E1
Standard weights - class E2
Standard weights - classes E0, E1, E2
Mass standards und Standard weights
Primary standards - class E0 As national standard and/or to show the national mass scale up to 50 kg. For calibration (tracing) of the mass standards of class E1 to national standards.
Mass standards - class E1 Adjustment, testing, official calibration and calibration instrument for the quality assurance of scales with more than 1,000,000 steps in accordance with DIN EN ISO 9001ff etc. For the calibration and official calibration of weights of class E2 in accordance with OIML R111 and E08. For high precision weighing or comparative measurements on measurement comparators.
Standard weights - class E2 Adjustment, testing, official calibration and calibration weights for precision scales of class I For the quality assurance of scales with fewer than 1,000,000 steps in accordance with DIN EN ISO 9001ff etc. For weighing or making comparative measurements on class I scales or on measurement comparators. For the calibration and official calibration of weights of classes F1 and F2 in accordance with OIML R111 and E08.
Marking The weights are not marked with their nominal value or with information on the unit. In order to differentiate between them multiple weights with the name nominal value in sets are marked with dots or stars. It is also possible to add up to 3 user properties (symbols, letters and numbers) in order to clearly identify the weights as test or measurement tools.
These user properties can be determined by the client when he places the order.
