7. What is the difference between calibration and inspection?
Calibration (Industry Metrology)
Calibration is a process used in industry metrology where the readings of an instrument are compared with those of a more accurate standard instrument. This process is essential for ensuring that measuring instruments used in various industries (like manufacturing, engineering, and science) provide accurate and reliable results. Calibration helps in identifying any discrepancies or errors in the instrument’s readings. The primary goal is to ensure precision and consistency in measurements for quality control and regulatory compliance.
Inspection (Legal Metrology)
Inspection is a part of legal metrology. It involves a set of activities including the verification, statement, and certification that a measuring instrument complies with the legal requirements and standards. This process is typically mandated by regulations and laws, especially for instruments used in commercial transactions, health, and public safety. Inspection ensures that instruments meet the necessary legal standards and are suitable for their intended purpose. It involves checking the instrument against predefined criteria and issuing a certificate of compliance or a verification mark.
8. Can the calibration result be incorrect?
No, calibration involves precise comparison with a more accurate standard. The calibration certificate itself does not evaluate the correctness of the instrument’s results. However there is possibility to order statement of conformity according to results of calibration.
9. Calibration with or without accreditation - what are the differences?
Accredited calibration is performed according to specific procedures and involves repeated measurements to determine average values and uncertainties. It includes the PCA marks, enhancing its credibility and international recognition.
Accredited calibration is supervised by third part – Lithuanian National Accreditation Bureau and ensured that our accredited activity meets the quality requirements of the standards.
10. What is a calibration certificate and what does it include?
A calibration certificate from Nordic Metrology Science includes detailed information about the instrument calibrated, the calibration results, measurement uncertainties, and conditions under which the calibration was performed.
11. Why is it worth calibrating measurement devices regularly?
Regular calibration reduces losses and costs by ensuring the accuracy and reliability of your measuring devices.
Nordic Metrology Science recommends calibrating devices at least every 12 months.
12. Does the calibration certificate have an expiration date?
No, a calibration certificate does not require a validity date according to EN ISO/IEC 17025:2018-2. The intervals between calibrations are determined based on guidelines like ILAC-G24.
13. How do I receive calibration/inspection documents?
Nordic Metrology Science primarily provides digital certificates sent to your email. Paper certificates are available upon additional request and incur an additional fee.
14. Electronic (digital) calibration certificate - is that sufficient for compliance?
Yes, our electronic (digital) calibration certificate meets all necessary requirements. Our adoption of digital certificates is in line with the European Union’s Regulation (EU) No. 910/2014, which governs electronic identification and trust services for electronic transactions within the internal market. This regulation guarantees that our electronic signatures and digital documents meet the highest standards of security and reliability as set by the EU.
It offers benefits like faster service lead time, easy access, and environmental friendliness.
15. What is a Statement of Conformity and non-conformity certificate?
A Statement of Conformity is not typically included on a calibration certificate unless requested. A non-conformity certificate is issued when an instrument does not meet the required standards.
16. What is measurement error and how is it addressed in calibration?
Measurement error is the difference between the measured value and the true value. During calibration, we address this by comparing the instrument’s readings with those of a more accurate standard.
17. What standards have you implemented in your company?
Nordic Metrology Science has implemented various international and industry-specific standards to ensure the highest quality of service and compliance with regulatory requirements.
We have implemented standards for calibration, testing and inspection activities (ISO/IEC 17025 and ISO/IEC 17020), management systems (ISO 9001), environmental protection (ISO 14001) and occupational safety and health (ISO 14001). The full list and accreditation certificates can be found here Accreditation.
18. What is the scope of accreditation for Nordic Metrology Science?
The scope of our accreditation includes a wide range of calibration services, covering various types of measurement instruments and methods, as defined by our accreditation body.
19. What instruments are you inspecting?
We inspect all instruments that are included in the State Register of Measuring Instruments of Lithuania. If the measuring instrument is not included in the register, we offer a control service during which the conformity of the measuring instrument is assessed.
20. How do you determine the specific points within an instrument's range where calibration is necessary?
At Nordic Metrology Science, we perform calibrations based on your specified calibration points.
The determination of specific points for calibration within an instrument’s range is guided by several key factors:
- Instrument Usage: The typical operating range of the instrument in its regular use. Calibration points are selected to cover the full spectrum of this range.
- Accuracy Requirements: Points where high accuracy is critical, especially in applications where precision is crucial, are prioritized.
- Regulatory Standards: Compliance with industry-specific regulations may dictate certain points where calibration is mandatory.
- Instrument Specifications: Manufacturer recommendations and the technical specifications of the instrument also play a role in determining these points.
- Historical Data: Past performance data of the instrument can indicate which points are more prone to drift or inaccuracy.
For example, if a pressure gauge used in a manufacturing process operates mostly between 20 and 100 psi, it would be prudent to calibrate it at several points within this range, such as 20, 50, 75, and 100 psi, to ensure reliable and accurate readings across its entire operating range. This multi-point calibration approach ensures that the instrument performs accurately under various conditions, providing confidence in its readings and compliance with any applicable standards.
