Testing, Quality & Accreditations
In the following, we would like to inform you about the meaning of the different testing and quality accreditations, labels and other key information frequently mentioned on our materials or that can be found on our product data sheets.
Topics such as harmful substances or emissions are very important for both the user and the occupants. Relevant emission accreditations like the EMICODE or the Blue Angel certification is proof of fulfilling stringent requirements.
To facilitate and document the sustainability of entire buildings, a number of building certification systems have been established in the past several years, such as DGNB, LEED, and BREEAM. Here it’s important to know that the individual products are not certified, but rather the building as a whole. Building products must fulfil certain criteria in order to be used in these green buildings.
Environmental product declarations (EPD), sustainability data sheets, and the UZIN Ecoline range offer information related to sustainability and emissions, and can also serve as proof in certification.
The EMICODE describes the emissions of products by assigning them to the emissions classes EC 1 Plus through to EC 2. Only EC 1 Plus (very low-emission) and EC 1 (low-emission) certification have practical significance. The EMICODE is the most prevalent environmental symbol for flooring installation products. The labelling is done voluntarily by the manufacturer based on product emissions tests, and licensing is done by the Association for the Control of Emissions in Products for Flooring Installation, Adhesives, and Building Materials (GEV). For the EMICODE accreditation products are inspected in a testing institute to make sure they comply with the EMICODE endorsement. The manufacturer faces sanctions in the event of violations, such as losing their EMICODE licence.

The Blue Angel is an environmental cerificate awarded by the federal government of Germany for the protection of people and the environment. It is awarded for different product categories based on relevant criteria. After external testing of the emissions, as well as fulfilment of other conditions related to components and packaging or data sheet information, the Blue Angel licence is granted by the German Institute for Quality Assurance and Labelling (RAL). This is the best known environmental symbol for consumers in Germany.

The product manufacturer uses the CE designation to show that their product meets the underlying European standard. Products for which there is a standardised EN norm (or ETAG), must carry the CE label and the manufacturer must provide evidence of quality assurance measures. The CE label on the product packaging conveys the significant technical features of a product, such as the compressive strength of a screed. Examples of installation materials include screed mortars (→ DIN EN 13813) or tile adhesives (→ DIN EN 12004). The CE label is not taken by itself as a quality feature of a product. However, the label means that the manufacturer takes responsibility for monitoring all the features declared on it and abiding by it over the long-term. In addition, the manufacturer must provide their customers with a declaration of performance for all building products that carry a CE label (generally on their website), which likewise declares the significant benefits of the product.
The German mark of conformity (also abbreviated to Ü mark) indicates the usability of a building product in Germany. The Ü mark is evidence that the product in question meets national building inspectorate guidelines set forth by the Deutsches Institut für Bautechnik (German Institute for Building Technology, or DlBt) to prove certain product features. This applies to floor covering or wood flooring adhesives, for example, which have been subject to requirement for licensing for about five years in Germany if these products are intended for processing in common rooms. In the case of adhesives, certification is granted if certain requirements on emissions behaviour are demonstrated through an appropriate emissions test.
However, the DIBt’s long-standing practice is no longer permitted to additionally regulate building approval for products that have already been granted the CE label, as this was the case for floor coverings and wood flooring, for example. With the C-100/13 decision of the European Court of Justice (ECJ) of 16 October 2014, these national additional requirements for building products harmonised by European standards (CE-labelled) are no longer permitted. The requirement for the Ü mark for these types of products was thus dropped as of 16/10/2016.
The IMO wheel or “wheelmark” is the symbol in use across the European Union, which endorses the product’s suitability for use on ships. A requirement is the existence of a defined flammability test for the product (EC type examination → module B) as well as regular supervision of quality assurance procedures at the production site by an authorised certification body (→ module D). The wheel is authorised by the IMO, International Maritime Organisation, a sub-organisation of the UN.
Here you can find all relevant certificates for “IMO certificates”.
Since 2012 in France, building products need to be classified by their emission levels and labelled with the emissions classes A+, A, B, or C. Whereby A+ is the best emissions class and C is the poorest. This labelling obligation applies for all building products that are used indoors on an ongoing basis. The manufacturer categorises their product into one of the four emissions classes based on a defined product emissions test.
The M1 label, for low-emission products, is issued by the Building Information Foundation RTS (Helsinki, Finland) and is mainly prevalent in the Scandinavian nations. There is an emissions test that must be conducted for this emissions label, but unlike most others also undergoes an odour test.
The German Sustainable Building Council (Deutsche Gesellschaft für Nachhaltiges Bauen - DGNB e.V.) awards the accreditation for sustainable buildings. The DGNB has developed a building certification system that fully assesses the building. It evaluates the ecological, sociocultural, and economic aspects of a building. In comparison to other building certification systems (LEED, BREEAM), the DGNB accreditation evaluates the economics of a building. Structures can be awarded DGNB Platinum, Gold, or Silver depending on their total score reached.
As a result, building products must meet specific criteria in order to be used at DGNB sites. The impact of products on indoor air quality is of great concern to the DGNB. The products to be used can achieve one of four quality levels for this, whereby 1 is the lowest and 4 is the best level of quality. A life cycle assessment for the whole building is also prepared in the DGNB system. EPDs play a role in this.
UZIN UTZ has been a DGNB member since 2008.
To make planning sustainable buildings easier, the German Sustainable Building Council developed the DGNB Navigator. The free online database holds all the information necessary about sustainable building products in one place. The data stored about these products, architects, and planners provides comprehensive information that was prepared to match about 50 DGNB criteria. Products with a complete LCA are also awarded the DGNB Navigator Label. If you enter the registration code from the Navigator Label on the DGNB Navigator homepage, you’ll be taken directly to the product page.
LEED is an American building certification system that is used internationally. LEED stands for “Leadership in Energy and Environmental Design”. The evaluation system sets standards for buildings that are top-performing for ecology.
Building products must meet certain requirements for VOC content and, since the last revision of the LEED system, indoor air quality. There are also requirements regarding the source and the proportion of recycled materials used.
Products that carry the “LEED contributing product” button on the packaging or product data sheet meet the VOC and indoor air quality requirements under LEED and are thus best suited for LEED projects.
BREEAM (Building Research Establishment Environmental Assessment Method) is a building certification system that originated in the UK which has since been implemented in many countries. The evaluation system provides a comprehensive examination of sustainable aspects of buildings. Buildings can be rated against the BREEAM criteria on a scale of “pass, good, very good, excellent, and outstanding”.
BREEAM also imposes requirements on products that mainly concern indoor air quality. In addition, certain health-threatening substances may not be used in BREEAM projects.
Environmental Product Declarations (EPD) are documents inspected by independent third parties, which state the environmental impacts of a product throughout its life cycle. They also contain information about emissions behaviour and fire resistance, among other things. They are awarded by the German Institute for Construction and Environment.
Learn more about the EPD here.
UZIN sustainability data sheets contain all the important information about the environmental performance of a product. They provide information about building certification (DGNB, LEED, BREEAM), accreditations and indoor air quality. They also contain short versions of the same life cycle assessment data that can be found in an EPD.
The UZIN sustainability data sheets are located on each product page, or can be sent upon request.
The UZIN ÖKOLINE is a product range that puts a special emphasis on good indoor air quality. Products that carry this logo are distinguished by two emissions accreditations, namely the EMICODE and Blue Angel.
