Kalibratie

Kalibratie met accreditatie

Houd uw kwaliteitscontrole nauwkeurig & traceerbaar en het vertrouwen van uw klanten hoog

Wereldwijde kennis en expertise binnen handbereik. Mitutoyo is uw partner voor hoogwaardig precisiemeetgereedschap en betrouwbare persoonlijke service. Sinds 1994 biedt Mitutoyo Nederland binnen haar marktsegment accreditatie aan. Hiermee voldoet Mitutoyo aan de internationale ISO 17025-norm, die van toepassing is op alle organisaties die beproevingen en/of kalibraties uitvoeren en waarbij de uitvoering onafhankelijk door de Raad voor Accreditatie gecontroleerd wordt.

Een geringe investering voor een maximum aan vertrouwen. Kalibratie met accreditatie geeft repetitieve en herleidbare meetresultaten en daarmee een hoger vertrouwen voor u en uw klanten;
Voor de beheersbaarheid van uw meet- en productieproces;
Om te controleren of uw meetmiddel binnen specificatie ligt;
U kunt aantonen dat uw standaarden en/of meetinstrumenten door een RvA-erkend kalibratielaboratorium gecontroleerd worden;
Om herleidbaarheid naar de meter aan te tonen, noodzakelijk voor herleidbare kalibratieresultaten en productbeoordelingen;
Ter voorkoming van foute metingen, om het risico van afkeur te minimaliseren;
Ter voorkoming van prijzige en tijdrovende herbeoordelingen van uw product;
Om de systematische afwijking(en) van uw meetmiddel in kaart te brengen, zodat afwijkingen eventueel kunnen worden gecorrigeerd;
Om historie (kennis) omtrent uw meetinstrument op te bouwen (stabiel of eventuele drift door slijtage, schade, etc.);
Bij kalibratiecertificaten is de meetonzekerheid door de onafhankelijke instantie RvA gecontroleerd en gevalideerd, zodat de meetonzekerheid van uw meetproces en productieproces in kaart kan worden gebracht;
Essentieel voor uw kwaliteitssysteem (beheersing meetapparatuur).

Waarom voor een geaccrediteerde kalibratie kiezen?

Welke instanties zorgen voor controle en afgifte van kalibratiecertificaten?

De Raad voor Accreditatie (RvA) in Nederland en de Belgische Accreditatieinstelling (BELAC) zijn de enige organen in de BeNeLux die de meetonzekerheid op uw machines onafhankelijk controleren. Het ILAC zorgt er middels Mutual Recognition Arrangements (MRA) voor dat bijna alle accrediterende instanties in de wereld uw kalibratiecertificaten accepteren. De lokale accrediterende organisatie heeft namelijk gecontroleerd dat Mitutoyo BeNeLux aan de ISO 17025 norm voldoet. De accreditatiemetingen (NEN-EN-ISO/IEC 17025:2017) worden door gekwalificeerde medewerkers van de Technische Dienst van Mitutoyo BeNeLux uitgevoerd. De afgeleverde certificaten passen in elk kwaliteitssysteem (ISO 9001, ISO/TS 16949, AS 9100, ISO 13485,…).

Mitutoyo´s Knowledge Base - Calibration

The Key to Reliable Measurement Results

Traceability

Traceability‘ is the key when it comes to calibration.

For calibrating measuring instruments or standards, which represent special values or limits, it is necessary to link/reference them to the physical base unit(s) they are meant for (e.g. the meter m).

More Details and Downloads

To obtain these links, the national metrological institutes offer calibrations with their national primary standards, which are the definitive definition or realization of their unit of measure.
Standards calibrated in this manner are so-called secondary standards.
The third level of standard, a standard that is periodically calibrated against a secondary standard, is known as a working standard. Working standards are used for the calibration of commercial and industrial measurement equipment.
For calibration, it is essential to use standards traceable to the primary standards, since we use the same units. To document this, the standards used with their valid calibration mark have to be stated in the calibration certificate.

A Quick Definition of

Calibration

Calibration is the process to determine deviations from a device or standard. This may include a validation of conformity (e.g. the product specifications) and to document the results, the method of calibration, and the standards used for the calibration a certificate of calibration will be created.

More Details and Downloads

Calibration (and recalibration) of measurement devices and working standards in the industries is necessary to confirm the proper function and more importantly, ensure quality.
To provide recognized calibrations, laboratories have to be at least accredited according to DIN EN ISO/IEC 17025
Measurement to a consistently high level of accuracy can only be achieved if instruments are periodically calibrated against traceable standards

Doing the Math

Measurement Uncertainty

Measurements are always uncertain to a defined quantity.

There are existing several statistical methods to obtain the uncertainty according to the confidence you need. Usually, the measurement of uncertainty is given with a confidence of ≈95%.

More Details

By watching to chain of calibrations, from primary standard down to working standard [see ‘traceability’], the uncertainty of measurement will rise, because every further calibration contains the uncertainties of the standards used and in addition the uncertainty of the method of the calibration. The uncertainty of measurement in fact reflects the quality grade of the calibration.
For calibration purposes, you are always looking for better standards and/or better methods to push your uncertainty of measurement stated in the calibration certificate.
For customer's purposes, it is an economic matter of requirements vs. price. In reality, the majority of customers aren't familiar with the uncertainty of measurement. This results in decisions being made mostly by predetermined standards set up in contracts or business guidelines.

Confirming the Competences

Accreditation

Accreditations - the reliable instrument confirming competence.

Calibration laboratories may obtain accreditation by their national accreditation body, which is the DAkkS in the Federal Republic of Germany, the UKAS in the UK, and the RvA in the Netherlands for example.

More Details

An accreditation by these bodies confirms that organizations such as testing, inspection, and certification bodies can undertake their activities competently in accordance with internationally recognized standards and in line with the regulatory requirements. This establishes confidence in the important work of these independent conformity assessment bodies and their services in all sectors of the economy.
Also, accreditation ensures the international recognition of conformity assessments, contributing to free trade in Europe and around the world.
Actually, accredited calibrations had become more of interest because of contracts and guidelines between the industry and their suppliers. Especially the automotive industry demands ‘more trusted’ calibrations for their suppliers.

More and more customers seem to prefer accredited calibrations because of some kind of insecurity with proprietary calibration.
