The Indoor Climate Labelling lists a series of requirements regarding product emission. Table 1 below summarises the emission requirements, that needs to be fulfilled in order to get an Indoor Climate Label. Please note that the Indoor Climate Label is divided into 3 emission classes and thus the values you find in table 1 refers to the lowest of the three classes (Emission Class 3). For details on the classes, see table 2.
The Indoor Climate Lablling is divided into three classes: Class 1, Class 2 and Class 3. Class 1 defines the products with lowest emission. The emission classes are defined based on the emission of formaldehyde and TVOC28. The products – regardless of which class they fall into – have to live up to the criteria listed in table 1. The emission classes are defined as follows:
What does ‘Indoor Relevant Time Value’ mean?
All Indoor Climate Labelled products have a so-called Indoor Relevant Time Value given in days. This time value is determined based on the the amount of time that passes until the emission subsides to an acceptable level (based on the standard test method given in ISO 16000-28). The time value is based on a sensory evaluation performed by a panel of at least 15 people. Ceiling products are further classified by the release of particles. By having an Indoor Relevant Time Value it is possible to compare the sensory impression of two labelled products to each other.
