Before applying for an Emission Classification of Building Materials, the product shall be tested in a laboratory approved by Rakennustieto according to the M1 testing protocol. All practical matters related to the testing, such as sampling, the required number of samples and the method of packaging and delivery of the product sample, are instructed by the laboratory.
The applicant is responsible for the costs related to the testing and pays them directly to the testing facility. The applicant shall document the sampling of the product sample using a sampling report from the laboratory and this sampling report shall accompany the product sample to the laboratory.
The emission testing required by the M1 Classification is based on the European harmonised test standard EN 16516 (Construction products: Assessment of release of dangerous substances. Determination of emissions into indoor air). More detailed instructions for the testing are given in the testing protocol, which defines, among other things, the sampling instructions, and the preparation of test specimens by product type.
If there is a conflict between standards and the testing protocol, the testing protocol has precedence. If the testing protocol does not cover the testing of a particular product type, the classification committee will decide how the product shall be tested. If the testing of a product type has not been addressed in the testing protocol or questions arise about the testing, the Product Manager of the Emission Classification shall be contacted before testing.
If the testing has not been carried out according to the classification committee’s decision and the testing protocol, the classification cannot be granted based on the testing and new testing is required.
Emission testing for the M1 Emission Classification includes:
The M1 Classification focuses on emissions from building materials and furniture to indoor air. The only compositional requirement for building products is that screed-type products (e.g. mortars, screeds and putties) shall be casein-free. The upholstery of office- and auditorium chairs shall not contain fungicides.
The limit values of the M1 Emission Classification are based on (area) specific emission rate (SER). These classification criteria are presented in Table 1. In certain cases, determining the area used as the basis for the SER calculation is challenging, in which case instead of the area-based surface emission rate [mg/m²h], it is possible to determine the surface emission rate per piece [mg/pc*h].
In this case, the comparison with the criteria of the M1 Classification is done using the reference room concentration [µg/m³] and the limit values shown in Table 2. The conversion of SER values to reference room concentrations is carried out using the formulae in standard EN 16516 and the loading factors (L) presented in the testing protocol.
Table 1. SER-based limit values of the M Classification for building materials and furniture.
For analytical reasons, it is more practical to compare the emissions of small (L = 0.05 m²/m³) and very small (L = 0.007 m²/m³) surface products to the M1 Classification limit values using reference room concentrations [µg/m3] instead of SER values [mg/m²h], see Table 2. Small surfaces include e.g. wooden beams, doors, windows and grouts, and very small surfaces e.g. sealants.
Table 2. Reference room concentration-based limit values of the M1 Classification for building materials and furniture.
The emissions of upholstered office chairs are compared with the limit values of the M1 Classification using the reference room concentrations [µg/m³], see Table 3.
Table 3. Reference room concentration-based limit values of the M1 Classification for upholstered office chairs.
In the list below you will find, in order of country, all laboratories Rakennustieto has approved to carry out emission tests for the M1 Classification. Please note that testing alone does not entitle a company to market a product as M1-classified. Only Rakennustieto can grant a product the M1 Classification.
