Correct handling of test weights is vital to ensure accuracy of the weights long-term. Having accurate test weights is essential for the calibration and routine testing of balances and scales. However, the challenge in many busy laboratories is that carrying out balance calibration and routine testing is a manual process, and it's all too easy to make a slip-up in handling the test weights. Considerable weighing errors can arise if a balance has been tested with mishandled reference weights.
How you handle, clean and store test weights can make a big difference in the accuracy of your weighing processes. Test weights must be handled with care.

The consequences of handling test weights incorrectly
If test weights are handled improperly or if test weights are used that are not suitable for the balance to be tested, considerable weighing errors may occur. For example, skin oils, dirt and changing ambient temperatures can affect weight accuracy. The percentage mass variation becomes particularly critical when using small weights or working with tight tolerances. If these issues are not addressed, operators may conduct tests with inaccurate weights, resulting in weighing errors as well as unnecessary costs associated with rework, waste disposal, and product recall.
