How often are the UKAS Accreditation Schedule and Certificate reissued?

The Schedule is reissued as required, so each time we add a new method or matrix to our scope the Schedule is updated. Certificates are issued in line with the UKAS four-yearly accreditation cycle.

Why has a disclaimer appeared on my report regarding when samples were received in relation to the time of sampling?

All our methods are validated based on a particular stability window, outside this time we are required to note any limitations this may place on results. More information can be found in the UKAS Policy on Deviating Samples.

Why do you need to know the sample type?

All our methods are validated based on specific sample matrices; we are required to note the limitations of analysis results for any other matrices. More information can be found in the UKAS Policy on Deviating Samples.

What does ‘pink colonies present’ mean on my report?

In the analysis of drinking water for coliforms, pink colonies may appear on the coliform plates. This growth is due to non-coliform organisms which may inhibit the growth of coliforms. We provide this information to enable you to make an assessment of future sampling requirements.

Can I use my own sampling containers for analysis?

Yes but please be aware a disclaimer will appear on your report, as our methods have been validated based on the use of appropriate containers which we can supply, at no extra charge.

Why are my results different from those I received from another laboratory, for exactly the same product?

Whilst laboratories may use common standardised methods, it is highly unlikely that two laboratories will ever produce identical results. This is due to a number of factors, including sample variability, the sampling process, different analytical methods, uncertainty of measurement and so on. We only ever issue results that we have 100% confidence in, supported by our ongoing performance in external proficiency schemes – so you can be guaranteed we get the right results for the samples you send us, every time.
