Testing and Certification Basis
Basis for granting the Insulation-KEYMARK is the European certification scheme for thermal insulation products "Specific CEN KEYMARK Scheme Rules for Thermal Insulation Products", which was created by the responsible European certification committee (QAC - Quality Assurance Committee). The certification scheme is based on the following European product standards:
- EN 13162 "Thermal insulation products for buildings - Factory made mineral wool (MW) products - Specification"
- EN 13163"Thermal insulation products for buildings - Factory made products of expanded polystyrene (EPS) – Specification"
- EN 13164 "Thermal insulation products for buildings - Factory made products of extruded polystyrene foam (XPS) – Specification"
- EN 13165 "Thermal insulation products for buildings - Factory made rigid polyurethane foam (PUR)products – Specification"
- EN 13166 "Thermal insulation products for buildings - Factory made products of phenolic foam (PF) - Specification"
- EN 13167 "Thermal insulation products for buildings - Factory made cellular glass (CG) products - Specification"
- EN 13168 "Thermal insulation products for buildings - Factory made wood wool (WW) products - Specification"
- EN 13169"Thermal insulation products for buildings - Factory made products of expanded perlite (EPB) – Specification"
- EN 13170 "Thermal insulation products for buildings - Factory made products of expanded cork (ICB) - Specification"
- EN 13171 "Thermal insulation products for buildings - Factory made wood fibre (WF) products - Specification"
These standards specify the requirements and testing procedures for thermal insulation products concerning the characteristics that are defined in the designation code.
Quality Criteria
The following quality criteria are subject to the testing:
For all applications:
- Thermal resistance and thermal conductivity
- Tolerances for length and width
- Tolerances for thickness
- Tolerances for squareness
- Tolerances for flatness
- Dimensional stability
- Bending strength
- Reaction to fire
For specific application, provided that these characteristics are declared by the manufacturer:
- Dimensional stability under specified temperature and humidity conditions
- Deformation under specified compressive load and temperature conditions
- Compressive stress at 10% deformation
- Tensile strength perpendicular to faces
- Bending strength
- Point load
- Compressive creep
- Water absorption
- Freeze-thaw resistance
- Water vapour transmission
- Dynamic stiffness
- Compressibility
- Apparent density
- Release of dangerous substances
Furthermore, the manufacturer has to operate a product related factory production control taking into account the elements of the EN ISO 9001.
The conformity assessment for the self- and third party-surveillance as well as the scope of application are set in :
- DIN EN 13172:2001-10 "Thermal insulation products - Evaluation of conformity"
Testing and Assessment
Only those thermal insulation products are granted to use the KEYMARK that were successfully tested by an accredited and approved registered Testing Laboratory and certifed by an acccredited Certification Body ampowered by the KEYMAK Management Organization, and thus proofed the compliance with the relevant EN Standards.
The KEYMARK certificate is valid for 2 years. It can be renewed for further 2 years if the monitoring measures and tests show continued compliance with all requirements.
