The accreditation of a laboratory to EN-ISO 17025 standard is rapidly becoming the most popular means by which labs assure customers that their product is fit for purpose. To maintain this accreditation the lab must submit to (and pay for) regular surveillance visits by their national accreditation body. Almost all labs offering environmental and water analysis are accredited to this standard, but it is by no means universal in labs serving the pharmaceutical industry and few research labs are accredited. The practicing chemist has little or no say in the development of the various guides and standards. The result is that because there is no sense of ownership the lab chemist seems to feel little affinity for them. The lab manager, working in a commercial fee for service laboratory is becoming more and more disenfranchised from the tools he or she depends on to deliver their product.

Peter J. Jenks BSc, MRSC, attended a meeting organized by the Royal Society of Chemistry's Water Science Forum, entitled 'AQC for Microbiological Analysis of Water - Sound Science or Black Art?'. The meeting was organized and attended by a number of professionals to discuss alternative perspectives for AQC. The meeting also aimed at exploring the existing AQC best practice and enquire whether guidance was needed on the interpretation of out of control aspects of such efforts. David Sartory made a presentation at the event where he distinguished the analytical challenges associated with chemistry and microbiology analysis. He made this presentation while reviewing the 'state of art' of AQC and its progress in water microbiology. He compared two 10 mL samples of water where one was sent to the laboratory for trace metal analysis, while the other was sent to the microbiology laboratory for the analysis of coliform contamination.

Some of the significant aspects of the ISO 17025 Standard for laboratory testing are testing. The standard had continued to be complied with for over a long period of time for conducting laboratory testing. ISO published the standard in 1999 and accreditation of testing and calibration laboratories was started. A revised version of the standard was released in 2005, harmonizing it with ISO9001-2000, which introduced a greater emphasis on the responsibilities of senior management along with a specific requirement for continual improvement of the management system and communication with the customer. Revisions to the standard needed to be made continuously to continue the existing rate of its growth and application for different kinds of laboratory testing. These revisions needed to be made in the standard to address technical and commercial issues associated with such testing.

The triangular relationship between ISO/IEC 17025, together with its parent the International Standards Organisation (ISO) and the International Laboratory Accreditation Cooperation (ILAC), is studied. ISO/IEC 17025 was written in a general way and covers all types of laboratories including chemical, biological, environmental, materials and physical testing. Since the latest version was issued in 2005 it has been pulled in various directions and is now used by both testing laboratories, and calibration laboratories. The Standard has also been used, in partnership with ISO Guide 34, as the basis for the accreditation of certified reference materials producers and together with ISO Guide 43 and with input from ILAC it became ISO Standard 17043 which is used to accredit providers of proficiency testing services. Since 2005 ISO/IEC 17025 has spawned an industry with consultants, publishers and advisors.

The ever-increasing demand for CRMs and PT services accelerated through the last decade of the 20th Century and into the 21st . It soon became very clear that the traditional producers of CRMs and suppliers of PT would be unable, or unwilling, to meet demand. Inevitably demand was met by small, specialist companies that saw an opportunity and moved into the market, offering products of many and varied qualities. For many years, since the first CRMs appeared at the turn of the 2O Century, the production of CRMs was mostly left to the public sector with bodies such as the US National Institute for Science arid Technology (NIST) and the European Union's Institute for Reference Materials and Measurement (IRMM) developing materials to meet new metrological challenges. Over the next 20 years Governments around the world have continued to outsource activities once delivered by civil servants so the demand for CRMs and PT has continued to increase.
