• ISO/IEC 17025

Laboratory Accreditation | Asbestos


In support of regulations, UKAS accredits a large number of Laboratories that carry out Asbestos testing to the internationally recognised standard ISO/IEC 17025.

The Control of Asbestos Regulations 2012 give minimum standards for protecting employees from risks associated with exposure to asbestos. An Approved Code of Practice (L143) and guidance (HSG 248) give practical advice on how to comply with legal duties set out in the Regulations. Critically;

  • Employers are accredited to ISO/IEC 17025 where they contract any person to perform asbestos air testing and site clearance (Reg 20)*
  • Employers are accredited to ISO/IEC 17025 where they contract any person to perform analysis of material to check for asbestos is (Reg 21)*

* Except where testing is conducted by the employer for their own needs. However, the criteria for meeting the requirements of ISO/IEC 17025 still has to be met.

In support of the regulations UKAS accredits the following areas of asbestos testing:
  • Sampling of air for fibre counting
  • Fibre counting (PLM/PCM)
  • Fibre counting (air and/or bulk) and Identification (SEM/TEM)
  • 4 Stage Clearance Process
  • Identification of asbestos in bulk materials
  •  Asbestos In Soils – Identification

Additionally, the following testing activities are also offered for accreditation purposes to add value to the suite of activities mandated by Regulation:

  • Sampling of bulk materials for asbestos identification
  • Water absorption – to clarify whether asbestos boards and tiles are classified as materials that require a licence to work on (eg AIB) or as asbestos materials that do not require a licence (eg Asbestos Cement)
  • Asbestos in soils – Quantification/free-fibre analysis
  • Fibre discrimination in air

Note: Fibre discrimination is only undertaken during the second analysis of a sample, i.e. after an initial fibre count has been undertaken, for which accreditation is required (see above).

Readiness Assessment Tool

We appreciate the journey to accreditation can be daunting, with this in mind we’ve created a Readiness Assessment Tool. Start your self-assessment against the expectations of ISO/IEC 17025 and find out how ready you are to apply click here.

UKAS Training Academy

To support our accreditation work, the UKAS Training Academy offers a range of public and on-site training courses. Our portfolio of courses provide UK & overseas delegates with knowledge and best practice of accreditation practices and conformity assessment systems.
