Product grouping: contact information

What is a product group?

Products that have very similar physical and chemical properties and application can be considered as a product group. Classifying products as a group must be first agreed on with the technical working group. The product groups are formed in the technical working group based on detailed information about the products chemical and physical characteristics. We will take the suggestions from the manufacturer in consideration when forming the groups.

You can apply for the product grouping by filling in the M1 application form. Please tick “New application” and attach a product grouping table (e.g. an Excel file) which includes the detailed chemical and technical product information regarding the entire product group. Please also attach technical data sheets and safety data sheets (if applicable) to the application. Please advise clearly that the application is about product grouping.

More information and templates for product grouping can be enquired via email from m1(at)


Prior to submitting a M1 application, products must be tested in an approved testing laboratory. Testing laboratories will provide all information regarding sampling, sampling size, packaging and delivery of the product sample. Additional information about the emissions testing can be found in the M1 testing protocol and standard EN 16516:2017+A1:2020.

The applicant must inform the testing laboratory about the information concerning the product sampling by using the sampling report obtained from the laboratory.

Tested parameters:

  • Total emission of volatile organic compounds (TVOC)
  • Emissions of volatile organic compounds (VOC) according to the EU-LCI list
  • Formaldehyde (HCOH) emission
  • Ammonia (NH3) emission
  • Emissions of CMR compounds belonging to category Carc. 1A or Carc. 1B in Annex VI to Regulation (EC) No 1272/2008 
  • Odour acceptance


After receiving the test result from the testing laboratory you can apply for M1 classification. Please attach following documents to your application:

  • test report
  • technical product details (e.g. technical data sheet)
  • safety data sheet or material safety data sheet (if applicable)
  • product grouping spreadsheet (if applicable)

All information provided by the applicant is handled confidentially in the technical working group. The working group is appointed by The Building Information Foundation RTS sr and it consists of impartial experts. Meetings of the technical working group are held once a month (excluding holidays) and the upcoming meeting dates can be found here. The classification is valid for three years at a time.

As we process a lot of applications, please submit your application in good time before the meeting date, at least four (4) working days prior to the meeting. Working group’s decisions and classification documents for approved applications will be delivered to the email address given on the application within two (2) weeks of the meeting.

If the composition and method of manufacturing has not changed during the 3-year classification period, the classification can be continued with a continuation application for another three years without retesting. The continuation application must include following attachments:

  • up-to-date TDS document(s) (or similar document such as a brochure that has all relevant technical data)
  • SDS document(s) for materials classified as chemicals
  • a signed and dated document stating changes made to the product(s) and their manufacturing process since the last application/testing (the document must include all relevant product and company names)
  • latest testing report(s)

After six (3+3) years the product must be tested again and a new test report delivered with the renewal application. In the case of a product group, you must contact the technical working group before sending products for testing. The technical working group will decide which product(s) should be tested. Upon renewal, you must submit the product group for reevaluation even if no changes have been made. Product groups are submitted for reevaluation using the online form with product grouping spreadsheet and TDS documents as attachments.

The certificate validity, quality control and obligation to notify changes

The validity of the classification is always three years. During this time the company has the right to use the M1 logo on their classified products and in their marketing material. The M1 logo is a registered trademark, which is administrated by Building Information.

The certificate holder is obligated to inform Building Information in advance about the changes in the manufacturing process, chemical content or physical characteristics of the product, if these changes have influence on the emission characteristics of the product.

Quality control of the classified products

The quality of the the classified products is controlled by random sampling each year. The technical working group selects the products for testing once a year and the testing costs are covered by Building Information.

A randomly selected product, which test result do not comply with the M1 limit values will be removed from the database and the right to use the M1 label is terminated.
