The quality and high standard of services provided by the laboratory is confirmed by the Accreditation Certificate No. AB 1689 awarded by the Polish Center for Accreditation. The scope of accredited testing is constantly expanding.

Benefits of accreditation:

  • test reports issued by PCA-accredited units can be recognized by institutions not only in Poland, but also in countries that are signatories to multilateral agreements (MLA/MRA),
  • accreditation is an important argument - sometimes a necessary one - when selecting suppliers in the domestic and international markets,
  • accreditation confirms the reliability of the results,
  • accreditation is objective evidence that organizations operate in accordance with best practice,
  • the accreditation confirms the high quality of services and the competence of the staff,
  • accredited entities provide reliable information on the basis of which decisions can be made.
