Why are verification weights important?
Verification weights are crucial for calibrating scales. Depending on the quality assurance requirements, companies need weights of different classes. With us you will find a selection of calibration weights for various purposes.
What is calibration or verification?
Calibration is required by law if you participate in "trade transfer", which includes the sale of goods by weight, the calculation of fees by weight and the production or control of pre-packaged goods. Calibration is carried out according to strict standards and is carried out by authorized bodies to ensure that the scales meet the requirements.
The importance of accuracy classes for test weights
The accuracy classes of test weights are determined according to the international OIML guideline R 111. The OIML, founded in Paris in 1955, issues recommendations for legal metrology, which are integrated into the relevant standards by national institutions. According to According to guideline R 111, test weights are divided into classes E1 to M3, where E1 represents the highest accuracy class.
The different accuracy classes at a glance:
E1 and E2: These classes are intended for precision test weights used in high-precision applications such as laboratories and calibration laboratories. E1 test weights offer the highest accuracy and require a DAkkS calibration certificate confirming calibration by a specially accredited laboratory. E2 check weights are slightly less precise than E1, but are still very accurate and are therefore well suited for high-resolution analytical balances.
F1 and F2: These classes are often used in commercial applications such as precision balances that require high accuracy but do not need to meet the extreme precision requirements of laboratories.
M1, M2 and M3: These accuracy classes are used for less accurate industrial scales and other non-legal for trade applications.
Selecting the right accuracy class is crucial to the precision and reliability of your scales. Our selection of test weights covers different requirements and purposes to ensure that your scales always deliver accurate results.
