The KOMO quality system is independent and objective

KOMO, set up in 1962 under the auspices of the Dutch government, is now a quality mark that is 100% voluntary and 100% private, intended for the building industry and infrastructure sector. The quality mark is widely used and recognised internationally.

Collective quality mark with reliable system

With participants in 48 countries on almost all continents, the KOMO quality system offers buyers and clients in the building and infrastructure sector a reliable, international quality compass. What is the ‘secret’ behind KOMO?

KOMO is a collective quality mark with a very thorough system that is strictly maintained. The KOMO quality system is designed as follows:

  • KOMO quality requirements for the building and infrastructure sector have been drawn up in advance by both market and government parties (‘all parties concerned’). Consequently, a broad consensus exists on which private requirements (requirements of market parties) and public requirements (requirements based on legislation and regulations) must be met;
  • The KOMO requirements are made binding by a so-called Committee of Experts in an Assessment Directive (Dutch BRL), which also fully describes the method used to test the product in accordance with the Assessment Directive. An Assessment Directive is a definitive document;
  • Only accredited certification institutions that have a licensing agreement with KOMO are permitted to carry out certification. First through an admission check, which must confirm that all requirements are met. A critical audit follows at least once a year to ensure consistent quality. Therefore: repeated, objective testing by an independent, expert authority;
  • Products that fail to comply do not receive a KOMO certificate. Products that no longer appear to meet the requirements after admission can lose their KOMO certificate.

Short and good: every KOMO certificate is based on collective, fixed requirements. Whether a product (raw material or other material) does in fact comply with this is tested by independent experts. Not once, but repeatedly. The certificate only remains valid if there is continued compliance with the requirements.

600.000 HOURS
600.000 inspection hours. Every year! Result: quality as promised.

Thousands of audits and inspections each year

Independent experts carry out thousands of audits, tests and inspections every year to check whether the KOMO Quality Mark can be issued (and/or to determine whether there is continued compliance with the requirements). This adds up to more than 600.000 staff hours spent on specialist work every year! That’s very reassuring.

Identify and report unauthorised use

Sometimes manufacturers carry the KOMO Quality Mark without permission. For this reason, if a raw material or material carries the KOMO Quality Mark, always check to ensure it is genuine. If in doubt, always ask for the official KOMO certificate and use our website to check whether that certificate is genuine and valid. Have you identified or do you suspect an imitation? Please report this to the KOMO organisation immediately.
