What is rolling proof?

rolling proof is a ongoing scheme of ring tests that started in 2015.

It is developed to support laboratories in meeting the requirements of accreditation bodies. According to advisory document EA-4/18:2010 analytical laboratories are requested to establish a PT participation plan for accredited analytical methods.

PROOF-ACS supports analytical laboratories in meeting the requirements of accreditation bodies by offering three different modules of rolling proof: 

How can laboratories benefit from rolling proof?

rolling proof offers:

  • A possibility to cover the full scope of pesticides and commodities within a multi-method over time:

    • A continuous change of the pesticides from test to test.
    • Changing commodities of each commodity group in each test.
  • Consistently high quality of the test material.
  • A clear and concise report (z-score evaluation, homogeneity and stability data).
  • Additional service: Evaluation with respect to 70-120% recovery of the spiked level.
  • Provision of a separate table according to the requirements of DAkkS and EA summarising the participation in the tests over time.
  • Full transparency - no hidden costs:
    • Blanks - included
    • Packing and shipment - included
    • Comprehensive and understandable evaluation - included
