Verify cable reaction-to-fire performance under the Construction Products Regulation through testing and assessment performed by a Notified Testing Laboratory supporting CPR classification and CE marking documentation.

CPR cable testing supports quality, regulatory and product compliance teams when cables are placed on the EU market for permanent installation in construction works such as buildings, roads and bridges. The scope includes electrical power cables, control cables and data communication cables, including optical fibre cables, that form part of the fixed installation in buildings. 

Testing framework and classification 

Under the Construction Products Regulation, cables used in construction works must demonstrate defined reaction-to-fire performance and be CE-marked before they can be legally placed on the EU market. Cables are classified according to CPR reaction-to-fire classes ranging from Aca to Fca, including additional parameters related to smoke production and acidity where applicable. 

Testing outputs and conformity context

Testing measures characteristics such as flame spread, heat release, smoke production and acidity of combustion gases. The results may be used as evidence within the CPR conformity assessment framework, including type testing and Factory Production Control (FPC) and provide documented reaction-to-fire performance for technical documentation, Declarations of Performance and CE marking procedures.

Manufacturers are responsible for completing the conformity assessment procedure before affixing the CE mark. Importers placing cables on the market under their own name are subject to the same obligations. The service is part of our expertise in electronic product compliance and also includes, for example, testing LAN cables.

Challenges

When cables are used in construction works, incomplete reaction-to-fire testing or documentation can prevent correct CPR classification and delay CE marking procedures.

Fire, smoke and acidity test results are difficult to align 

Reaction-to-fire classification is based on several interrelated tests. When results across flame spread, heat release, smoke and acidity are inconsistent or incomplete, the combined test evidence cannot be used to establish a valid CPR classification. 

 

Cable design changes invalidate previous test results 

Changes in materials, insulation compounds or cable construction may fall outside the configuration covered by existing CPR test evidence. This requires new testing before the reaction-to-fire classification can be documented. 

 

Missing documentation blocks CPR conformity procedures 

Without traceable test reports, the reaction-to-fire classification cannot be documented and the Declaration of Performance cannot be issued.
