Termination and renewal of certificate 

Background for the scheme

Certification rules were included in the standard INSTA 800 "Cleaning Quality - System for Determining and Assessing Cleaning Quality" was certified by an audit in 2010. The standard was again released in a revised version in 2018 and is now divided into two parts; INSTA 800-1 and INSTA 800-2. Part 1 of the standard deals with the system for measuring the quality of cleaning, while conditions for the 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.
SINTEF certifies people for level 3 and 4 according to the standard part 2. The certification is carried out and followed up in accordance with the requirements of NS-EN ISO IEC 17024.
The purpose of the certification for INSTA 800-1 is to document that users of the standard have the necessary knowledge to work with the standard properly. The standard requires that documentation of such knowledge shall be made through certificates issued by a third party's certification body. A certification can aid:
  • General competence enhancement among users of the standard, for the benefit of both cleaning and receiving service providers and customers of cleaning service providers.
  • Correct use of the standard by:
    • The preparation of tender documents
    • Plans for cleaning
    • Determining quality requirements; ensuring that the requirements are set at the right level
    • Quality controlling; the correct result (true value) and the intended degree of reproducibilty in quality controls
  •  Avoidance of misuse of the standard, such as adaptations that are not acceptable in relation to the limits and requirements of the standard.
Certificates are issued in Norwegian, Danish or English. Norwegian certificates refer to the Norwegian version NS-INSTA 800-1: 2018, and Danish certificates refer to the Danish version DS / INSTA 800-1: 2018. Certificates in English are issued primarily to holders in the other Nordic countries, with reference to the English version of the standard DS / INSTA 800 E: 2018.
DS / INSTA 800 E: 2018 is the superior version of the standard.

Update of certificates after release of new version of INSTA 800 in 2018

As a result of the standard being revised, all holders of certificates must document that they have expertise in the revised standard. The deadline for this is set at 01.01.2020 for Danish holders, and 01.07.2020 for Norwegian holders.
Valid documentation is course and diploma proving participation in an update course held by one of SINTEF's partners. For the sake of the EU's new rules on privacy that apply from May 2018 (the Privacy Policy, The General Data Protection Regulation, GDPR), a new certification agreement must be entered into with all holders. A completed "Application Form and Agreement on Certification" must therefore be submitted together with the course and diploma.
Based on the submitted application and documentation, SINTEF Certification issues renewed certificate. The certificates are given a validity of 5 years. Renewal cost is NOK 1850. The renewed certificate is issued as soon as invoice for the renewal has been paid.
Exception: Certificates with more than 2 years remaining vailidity can be renewed without any certifications cots, provided all other costs (annual fee) have been paid
