UKAS Scale Calibration – Accredited Laboratory 0780

Weightron provides UKAS scale calibration services for a diverse range of companies in markets including automotive, aerospace, MOD, general engineering and manufacturing. 

We have held our prestigious UKAS accreditation since 2003 and this stands testimony to the rigorous in-house ISO IEC 17025 and ISO 9001 quality systems and procedures.

Why do companies need to use the services of an accredited laboratory for their weighing equipment?

If you can answer ‘yes’ to one or more of the following questions then you should talk to us about UKAS scale calibration.

  • Are you required to use accredited services by your customers?
  • Does your business operate in an environment where test results are safety-critical e.g. construction materials?
  • Does your business operate in an environment where the accuracy of test results have legal repercussions?
  • Are you receiving poor results from existing suppliers?
  • Are you looking to de-risk your supply chain?
  • Is the technical competence of your supplier essential to your business?

 Background

UKAS is the sole accreditation body recognised by government to assess, against internationally recognised standards, organisations that provide inspection services. UKAS combines a depth of technical knowledge and expertise built up over many years with scientific and technical specialists operating across a range of inspection activities. They sum up why companies should choose an accredited UKAS laboratory like Weightron for their equipment calibration:

“The competence of the inspection body you appoint may be crucial to maintaining your reputation as a responsible organisation! It is therefore surprising that organisations are still tempted to use the services of inspection bodies whose competence has not been confirmed by an independent, authoritative third party.

So why leave something so important to chance? There is a tried and tested way of ensuring that an inspection body is up to the task, and that is by using one that has been accredited for the specific activity by the United Kingdom Accreditation Service (UKAS).”

The standard ISO/IEC 17025:2005 [General requirements for the competence of testing and calibration laboratories] specifies requirements for reporting and evaluating uncertainty of measurement.The problems presented by these requirements vary in nature and severity depending on the technical field and whether the measurement is a calibration or test.

Calibration is characterised by the facts that:

  • repeated measurements can be made
  • uncertainty of reference instruments is provided at each stage down the calibration chain, starting with the national standard and
  • customers are aware of the need for a statement of uncertainty in order to ensure that the instrument meets their requirements.

Consequently, calibration laboratories are used to evaluating and reporting uncertainty. In accredited laboratories the uncertainty evaluation is subject to assessment by the accreditation body and is quoted on calibration certificates issued by the laboratory.
