DIN EN ISO 9001 certification:this certification signifies that a company has demonstrated that they have adapted their entire management system to meet the DIN EN ISO 9001 standard of quality. After inspection by the relevant authorities, the company is awarded a DIN EN ISO 9001 certificate of quality according to the management system they have in place. This certificate is completely different from that of the ENAC calibration certificate which relates to the relative characteristics of the technical measurements made by measuring instruments. Certification according to DIN EN ISO 9001 is also not identical to an accreditation for as yet there is no accords here as to the effects of international recognition.
Factory calibration certificate: Factory calibration certificates are issued with standards that are that are a result of subjecting the measuring device to rigorous quality control measures. Quality is assured as the instruments used for quality control are regularly maintained to ensure the highest level of accuracy. The measuring instruments are then adjusted using a quality control device and calibrated within the factory.
Calibration interval: To ensure that correct measurements are being taken, the device should be calibrated periodically. This period of time is known as the calibration interval. It's impossible to accurately determine when a device will require calibration, however, it always helps to have a guide, and here are a few key things to consider as an indication:
-
Measurement value and the permitted range of tolerance.
-
Performance of the measuring instruments.
-
Frequency of use.
-
Operating conditions.
-
Stability of previous calibrations.
-
Accuracy required for the measuring instruments.
-
Quality control requirements of the company.
This means that the same user should have responsibility during a calibration interval. Measurement margin of error: Margin of error of readings with respect to real measurement value. Factory calibration certificate: These certificates are issued by accredited manufacturers that can ensure the devices meet the stringent requirements for accuracy and reliability.
Conformity certificate: Compatibility between two devices and official documented approval during calibration by the notifying body issuing the conformity certificate.
Certificate of revision: Certified with the factory confirming that the product being delivered meets the product specifications. (data sheet).
