Calibration Certificates

Traceability for your devices to provide security & ensure quality

Calibration Certificate vs. Device Report

Measurement equipment calibrated by a Michelli Weighing & Measurement service technician includes a Device Report. You also have the option of obtaining a Calibration Certificate for an additional fee. This fee is used to cover the cost associated with maintaining our measurement standards.

A Calibration Certificate is different than a Device Report. A Calibration Certificate provides security by providing a paper trail that includes traceable numbers to prove that your equipment was measuring accurately at the time of your last calibration. A Calibration Certificate includes detailed and traceable information, which is a critical component to confirming/proving that your measurement equipment is operating properly, accurately, and that you know both AS FOUND and the AS LEFT test point results when compared to a traceable standard.

​Benefits of a Calibration Certificate:

 

1. Audit protection

      • Michelli Weighing & Measurement stores your Calibration Certificate on 3 separate hard drives, on 3 separate systems to ensure your cert is never lost.
      • Assurance that stored copies of your Calibration Certificates are quickly accessible to provide your auditor during both internal and external audits.

2. Protection against accidents or warranty claims

      • A Calibration Certificate ensures that NIST traceability can be proven, so that in the event of a product malfunction, you can prove that you have completed all necessary equipment calibration maintenance to ensure accuracy of your measurement equipment.
      • The Calibration Certificate provides proof that the equipment used during production was certified to a NIST traceable standard, ensuring that the equipment was producing accurate results & functioning within recommended factory specifications.

3. Quality Assurance

      • Both the date of last calibration & the recommended date of the next calibration are given on the Calibration Certificate.
      • The date of calibration provides assurance that the equipment you use to ensure quality is measuring accurately, within the manufacturer recommended tolerance range, as of a certain date.
      • The calibration “due” date provides a window during which you can rest assured that the equipment you are using to measure quality is providing accurate readings.

4. Proof of Compliance & Due Diligence

      • A Calibration Certificate helps provide a paper trail that proves due diligence.
      • With a Calibration Certificate, an organization is able to prove that they have calibrated their equipment as of a certain date, and that the calibration was performed using NIST traceable equipment, leading the organization to believe that all measurements produced were accurate.

​Standard NIST Traceable Calibration vs. ISO 17025 Accredited Calibration

Some applications require standard NIST traceable calibration, while others require ISO 17025 accredited calibration. Michelli Weighing & Measurement can help with both of these services. What’s the difference?

Standard NIST Traceable Calibration

A Standard NIST Traceable calibration, aka “standard calibration” ensures that your equipment has been compared to, and if necessary, adjusted to match, a standard that was calibrated and certified traceable by NIST, an agency of the U.S. Department of Commerce. In the most basic terms, our measurement standard has been calibrated against a NIST measurement standard, and we have the traceability documents on record to prove it. A Standard NIST Traceable calibration has to do with the traceability of the equipment used to perform the calibration, rather than the competency of the service agent or laboratory performing your calibration

 

ISO 17025 Accredited Calibration

In contrast, an ISO 17025 accredited calibration, aka “accredited calibration” means that the calibration is recognized internationally & the device has been calibrated by an ISO 17025 accredited calibration lab. In order to obtain ISO 17025 accreditation, a calibration lab must undergo regular audits that deem the lab competent to perform “accredited” calibrations. A Scope of Accreditation lists the types of measurement devices, and the ranges of each, on which a calibration lab is authorized to provide accredited calibrations. So an ISO 17025 accredited calibration has to do with the competency of the service agent, along with traceable equipment, that is performing a calibration. If the level of safety in a given situation could be compromised by inaccurate weighing & measurement equipment, ISO 17025 accredited calibration is typically required.
