  • We ensure that all our employees are skilled and qualified in the services they provide. All of our employees are familiar with the quality assurance documentation and implement the guidelines and procedures in their work.
  • Compliance with all legal and further quality requirements form the foundation of the work carried out in our company.


Our laboratories are accredited in accordance with  EN ISO/IEC 17025. This accreditation standard comprises all quality aspects for testing laboratories, including the testing process, test equipment monitoring, method and equipment validation and employee competence. The accreditation of our laboratories is monitored regularly. As an accredited laboratory, we also participate in all of the relevant audit programmes in order to secure our technical expertise.

Our accreditation is further proof of the commitment of WESSLING to excellence and leadership in this sector.


Europe-wide accreditation validity

The EA (European Accreditation) is an association of national accreditation bodies in Europe which are officially recognised by their national governments. They evaluate and verify the international standards of organisations which perform evaluation services such as certification, auditing, inspections, checks and calibration. Membership of the NAH [Hungarian National Accreditation Authority] in the EA means that our accreditation is recognised on a European level. This recognition on a European level reinforces our customers’ confidence in the competence, independence and impartiality of our tests.

Based on the decisions made by the National Accreditation Authority (NAH) the Environmental Analytical Laboratory and the Food Testing Laboratory of WESSLING Hungary Kft. hold the certification of independent testing laboratory under the registration number of NAH-1-1398/2019 up to 17 October 2024 and under the registration number NAH-1-1009/2019 up to 17 October 2024, respectively. Having regard to the fact that the National Accreditation Authority (NAH) is a signatory to the mutual multilateral recognition agreements of both the European Cooperation for Accreditation (EA) and International Laboratory Accreditation Cooperation (ILAC), the accredited tests made by the laboratories are accepted not only in this country but abroad just as well. . A list of countries including Serbia which are members of the ILAC and therefore mutually recognise the accreditation of member countries is available at: http://ilac.org/
