Sampling and Testing laboratory certification


Where an organisation used for the analysis of indoor air or emissions from building products is not accredited to ISO/IEC 17025, the organisation must be accredited, either by a national accreditation body, or by a member of any one of the following accreditation groups:

European Cooperation for Accreditation

International Accreditation Forum

International Laboratory Accreditation Cooperation

The accreditation must specifically cover the analysis of indoor air or emissions from building products.



Where the sampling is undertaken by any party other than a company which is accredited as above, they should provide a brief report justifying the following:

  • The sampling methodology used
  • Appropriate environmental conditions during the sampling
  • The number and location of samples taken

In such cases, this report should be provided to the BREEAM assessor and submitted as supporting evidence for this Issue.
