KERN offers you the appropriate test weight package for your balance, consisting of the test weight, box and DAkkS-calibration certificate, as proof of its accuracy.
Weights have always been used to carry out weighing procedures. This original purpose has almost disappeared. Today, weights are used almost exclusively for adjusting and testing = calibration of electronic balances. We therefore call them “Test weights” as this is their purpose of use.
The internationally valid OIML norm R111:2004 classifies test weights hierarchically in accuracy classes, where E1 is the most accurate and M3 is the least accurate weight class. With KERN you get the whole test weight range in all OIML accuracy classes E1, E2, F1, F2, M1, M2, M3.
As the appropriate test weight is only classed as checking equipment according to ISO 9000ff if it has the relevant proof of accuracy, all KERN test weights come with an appropriate DAkkS-calibration certificate.
Test weights: classes of accuracy E, F, M and their general relation to the types of balances:
- E1 Test weights for customers who require a high degree of accuracy for the most demanding applications. For high-resolution balances with d > 1,000,000 Use recommended with DAkkS calibration certificate only
- E2 Most accurate test weights for high resolution analytical balances of verification class I ≥ 100,000 e
- F1 Test weights for analytical balances/precision balances for verification class I/II ≤ 100,000 e
- F2 Test weights for precision balances of verification class II ≤ 30,000 e
- M1 Test weights for industrial and commercial scales of verification class III ≤ 10,000 e
