You may not even know whether you need certification, let alone what kind, so here is a rough outline to the
certification we can offer.
Standard Traceable Calibration Certificate. This is the most basic and lowest cost certificate that we offer and is issued by our service centre staff under procedures controlled by our BSI audited ISO9001 quality management system using comparator weights traceable to National Standards . One certificate will cover all weights of the same tolerance, and will state that the weights are all within tolerance. This will satisfy many quality management requirements.
Standard Traceable Calibration Certificate with Numbering This is as the Standard Traceable Calibration Certificate but additionally the weights are given identification numbers (these can be chosen by yourself or we can assign them). Each weight is then identified on the certificate with its exact reading, this will allow you to identify any calibration drift between calibrations and will satisfy all quality management requirements unless UKAS certification with uncertainty of measurement is required.
Trading Standards Certificate This is only for Newton or Trade Stamped test weights. It is similar to our standard traceable certificate except the weights are sent off to Trading Standards to be certified. One certificate will cover all weights.
UKAS Certification. UKAS stands for United Kingdom Accreditation Service and is the sole national accreditation body recognised by the British Government. This certificate is issued by Trading Standards and is a higher level of certification than the Standard Traceable Certificate. The calibration is performed under laboratory conditions and shows the uncertainty of measurement to be given with a 95% confidence level. One certificate is required per weight.
DKD Certification. DKD is the German Equivalent of UKAS. As one of our main weight suppliers is based in Germany, it is quicker and less expensive to have DKD certification rather than UKAS. DKD is recognised by UKAS as being equivalent so will still fulfil any requirements you have for this level of certification.
