Background for the scheme

Certification requirements in INSTA 800-2

The standard INSTA 800 " Cleaning quality - System for establishing and assessing cleaning quality " became certifiable in the revision in 2010. The standard was again published in a revised edition in 2018, and is now divided into two parts; INSTA 800-1 and INSTA 800-2. Part 1 of the standard includes systems for measuring cleaning quality, while conditions for declaration of conformity that can form the basis for certification of users of INSTA 800-1 have been moved to part 2 of the standard.
Compliance with the competence requirements for Knowledge Level 3 and Knowledge Level 4 can only be declared through documentation issued by a third-party certification body. The certification body must be able to demonstrate compliance with EN ISO/IEC 17024 and demonstrate certification according to this standard as its area of activity.

The purpose of certification for INSTA 800-1 is to document that users of the standard have the necessary knowledge to work with the standard correctly. The standard requires that documentation of such knowledge be done through certificates issued by a third-party certification body. A certification can contribute to:
  • general competence enhancement among users of the standard, to the benefit of both those performing cleaning and recipients of cleaning services
  • that the standard is used correctly for:
    • preparation of tender documents
    • planning of cleaning
    • determination of quality requirements; ensure that the requirements are placed at the right level
    • quality control; correct results (true value) and intended degree of reproducibility in quality controls
  • to avoid misuse of the standard, for example adaptations that are not acceptable in relation to the framework and requirements given in the standard.

Knowledge levels in INSTA 800-2

Knowledge level 3 is recommended for people who carry out INSTA inspections, supervisors and buyers. The owner has detailed knowledge of all/large parts of the INSTA 800 series.
Knowledge level 4 is recommended for everyone who teaches INSTA 800, customer and supplier contract managers, planners and people who prepare offers. The certificate holder masters the use of the INSTA 800 series in every way.
Knowledge levels 1 and 2 do not require any certification and are recommended for administrative management and cleaners respectively.
