The calibration of a scale ensures that the measured values of your devices are exact and reliable. With regular calibration, you prevent errors, avoid production downtime and ensure compliance with legal standards. An uncalibrated scale can lead to long-term quality losses, legal problems and unnecessary costs.
As a specialist with over 20 years of experience, BOSCHE offers you professional calibrations that guarantee precise measurements and stable processes. Our certified technicians carry out calibrations with both a factory calibration certificate and an internationally recognized DAkkS certificate. We work according to the strict requirements of DIN EN ISO / IEC 17025 and guarantee the highest level of accuracy.
With customized calibration plans, we support you on time and offer adjustments and repairs directly on site. Thanks to continuous training, our team always stays up to date with the latest technology.
Contact us to have your scales calibrated professionally and promptly. Our certified technicians are available to check and adjust your scales for maximum accuracy.
Calibration describes the process of checking and documenting the measurement accuracy of a scale. This involves determining the deviation of the display from a specified reference value. After successful calibration, you will receive a certificate confirming the measurement accuracy of your scale.
The frequency depends on the operating conditions. For industrial applications, we recommend annual calibrations.
No, but it is standard in many industries and necessary to comply with quality management standards (e.g. ISO).
Non-calibrated scales lead to inaccurate measurements, which can lead to quality problems and legal consequences.
Factory calibration is carried out internally, while DAkkS calibration is performed by an accredited laboratory with international recognition.
The duration depends on the type of scale, but a calibration usually takes a few hours.
Factory calibration | Calibration (according to DAkkS) | Calibration |
---|---|---|
Factory calibration is not regulated by law. | Calibration according to the DAkkS specifications is not regulated by law. | Calibration is regulated by law. |
Reason for factory calibration “Outlier” for devices, equipment was reactivated after a long time, general check "Does my equipment still work properly?". |
Reason for calibration If the test weight or scale is used within a quality management process , a calibration should be carried out beforehand according to DAkkS specifications. |
Reason for calibration It is required by law as soon as you are involved in so-called ‘trade transfer” participates. This includes, for example, the sale of goods by weight, the calculation of fees by weight as well as the production or control of pre-packaged packages, etc. Further information on this can be found in the calibration law. |
What can be factory calibrated? Test equipment and measuring devices that do not follow a calibration routine according to DAkkS are subject to and are not subject to calibration. |
What can be calibrated? All error-free test equipment can be calibrated according to DAkkS.< /td> |
What can be calibrated? Only “verifiable” items can be calibrated. Scales with type approval and test weights that are calibrated in accordance with the OIML (Organization Internationale de Métrologie Légale) requirements. |
Expiry Is not set. Is carried out, for example, in the same way as the conformity assessment (calibration). The measurement deviations are specified using calibrated weights. After completion, a factory calibration certificate will be issued. |
Process A laboratory accredited by DAkkS tests the test equipment for accuracy through traceability internationally recognized standards. Such a calibration may only be carried out by highly qualified specialist personnel who have presented themselves to the DAkkS certification body. A calibration certificate will then be issued. |
Procedure Balances and weights are checked for calibration error limits (maximum permissible errors). This is done by the manufacturer (only during manufacturer verification) and the calibration office (within the legally prescribed intervals). A stamp certifies that the measuring device met the requirements at the time of the test and that it was “correct” when handled in accordance with the rules of technology within the re-verification period. remains. |
Validity The DIN EN ISO 9001:2015 (7.1.5.2) leaves the user to select the appropriate testing procedures. As a rule, a factory calibration is sufficient provided that traceable test equipment was used. |
Validity International recognition is achieved through multilateral agreements on mutual recognition between EA (European co-operation for Accreditation) and ILAC (International Laboratory Accreditation Cooperation). In Germany, the German Accreditation Body (DAkkS) monitors this. |
Validity A declaration of conformity with CE applies to the European Union -Labeled as “first attempt”. Nationally, only re-verification and national declaration of conformity are recognized. |
How often? A factory calibration can be carried out as often as the operator of the measuring devices requires and testing equipment makes sense. According to 9001:2015, the user sets the cycle after use. |
How often? The operator of the measuring devices and test equipment is responsible for compliance with the respective recommended periodic recalibration periods. |
How often? By law, the re-calibration periods for test equipment and measuring devices are set nationally Specifications set. |
