21 - 21
Test weights play an important role in quality assurance and calibration of balances and other measuring instruments. They are used to verify the accuracy and reliability of these devices and to ensure that they provide correct measurement results.
Test weights are manufactured to international standards and are subject to rigorous testing procedures to ensure that they meet the required tolerances. They are usually made of high quality stainless steel or other high density materials to ensure accurate and stable mass.
There are different types of test weights that are used depending on the application and requirements. The most common are single weights, which are available in different weight classes, and weight sets, which contain a number of weights in different combinations.
An important feature of test weights is their traceability. This means that the mass of the test weight can be traced back to a national or international standard. This is achieved by regularly checking and certifying the weight by accredited calibration laboratories. Traceability is critical to ensure that measurements are made on a reliable basis and are internationally recognized.
Test weights are used in many applications where accurate measurements are required. This includes industry, healthcare, research and development, and the food and pharmaceutical industries. In industry, for example, test weights are used to check the accuracy of production scales and ensure that manufactured products meet specifications.
In the food and pharmaceutical industries, test weights are critical to ensure that scales provide accurate measurements for ingredient or drug dosing. Incorrect measurements could lead to production errors or even health risks.
The regular inspection and calibration of scales with test weights is not only a requirement for compliance with quality standards, but also a prerequisite for certifications and accreditations. Companies that do not have their scales calibrated regularly risk not only regulatory violations, but also financial losses due to production errors or recalls.
Overall, test weights are an indispensable tool in quality assurance and calibration of measuring instruments. They ensure the accuracy and reliability of scales and other equipment and play an important role in many industries. Regular inspection and calibration of scales with test weights is therefore essential to produce high-quality products and ensure consumer safety.

How are test weights manufactured and calibrated?
Test weights are usually made from various materials such as stainless steel, brass or iron. The manufacturing process can vary depending on the material, but generally involves the following steps:
1. Selection of the material: Depending on the application and accuracy requirements, materials with a high density and resistance to corrosion are selected.
2. Casting or molding: The selected material is shaped into the desired form. For smaller weights they can be cast, while for larger weights forging or machining methods can be used.
3. Editing: The raw weights are mechanically processed to achieve the desired dimensions and surface finishes. This can include grinding, turning, milling or polishing.
4. Calibration: After manufacture, the test weights must be calibrated to ensure that they have the desired accuracy. This is usually carried out in specialized laboratories or facilities.
Calibration normally involves comparative measurement of the weight with a reference scale with high accuracy. If the weight deviates from the desired accuracy, adjustments can be made to correct it. This can be done by adding or removing material.
After calibration, the test weights are normally given a protective coating to protect them from corrosion. They are then stored in special containers or cases to prevent damage.
It is important to note that test weights should be manufactured and calibrated according to specific national or international standards to ensure measurement accuracy and traceability.

How often should test weights be checked and calibrated?
As a rule, test weights should be checked and calibrated at least once a year. With frequent use or in particularly demanding environments, it may be necessary to carry out the check and calibration more frequently. It is also advisable to check the test weights after a repair or after a fall and to recalibrate them if necessary. It is important to adhere to the manufacturer's specifications and, if necessary, use a professional calibration service to ensure the accuracy of the test weights.
What requirements must test weights meet to be considered suitable?
Test weights must meet certain requirements to be considered suitable. Here are some important requirements:
1. Accuracy: Test weights must be highly accurate in order to ensure the desired precision when calibrating scales or other measuring devices. The accuracy class of the test weight provides information on the permissible deviation from the nominal load.
2. Traceability: Test weights must be traceable, i.e. their accuracy must be traceable to national or international standards. This is guaranteed by appropriate calibration certification and compliance with national or international standards such as ISO 17025.
3. Material and construction: Test weights should be made of a material that maintains a stable mass over a long period of time. Common materials are stainless steel or brass. The design of the test weight should ensure an even distribution of the mass in order to minimize measurement errors.
4. Labeling: Test weights must be correctly labeled to clearly indicate their nominal load and accuracy class. This makes it easy to identify the weight and facilitates proper use.
5. Storage and handling: Test weights should be stored in a suitable environment to avoid deterioration or contamination. They should be checked regularly for wear or damage. When handling the weights, suitable precautions should be taken to avoid damage or contamination.
