Analysis according to ISO 17025

Dear all,

I sometimes get the following question from customers:

Did the testing laboratory perform the analysis according to ISO 17025 or another equivalent method?

I never know what exactly is meant and cant find an explanation online.

Can someone help me with this?

The last question was about the analysis that is attached.

https://www.iso.org/...dard/39883.html  This is a link to the standard.  It is a standard of analysis designed to ensure all labs are performing testing the same way......it is to remove the margin of error; also not all labs have been certified to perform all tests.....some can do listeria and salmonella, but not campy etc etc

Call the lab you use and ask them, they will tell you if they are accredited or not OR there may be a comparable national standard where you live.  I had to look up the standard too. In Canada accredited labs are either CALA or SCC both of which suffice against CFIA and 3rd parties

As Scampl has noted, ISO 17025 is a standard for laboratory analysis. A laboratory that has been accredited to this standard is highly regarded as they perform their  tests to the required certified standard. This means that any laboratory tests captured under this certification have been validated to the required analytical standard and you should expect any certified lab for that test to produce near identical results on the same sample.

Down under any Lab that is certified to this standard is typically certified by NATA - National Association of testing Authorities Australia. Note however even thought they are certified to this standard some of their analytical tests methods may not be certified to the specific standard for that analytical method. So where a lab is certified to the  ISO 17025 standard you need to understand the scope of that certification and what analytical methods are captured in that certification.
