Proficiency Testing - UK Man Made Mineral Fibres (UK MMMF)

Proficiency testing
The UK MMMF scheme assesses the proficiency of laboratories counting Man Made Mineral Fibres (such as glass) in air.

The MMMF scheme is operated by HSL, which oversees management, registration, and membership matters.

Analytes in the scheme
MMMF fibres mounted on microscope slides.

Operation of the scheme
Eight test slides are sent to laboratories every three to four months. Laboratories have 7 days to analyse the samples and 14 days to report the results. Performance is categorised as A, B or C and provided more than 75% of results are in the A or B category after four rounds then a laboratory is classified as 'satisfactory'. This scheme is a round robin where sets of slides are circulated between groups of laboratories.
