CPR
CPR
The CPR (Construction Products Regulation) aims to ensure the protection of people's health by ensuring safety in various dimensions of construction. It defines a standardised classification for all cables that are permanently installed and requires that all cables have a performance declaration and CE marking when marketed and sold.
The CPR certification requires that cables are classified according to fire properties, tested by a third party, and must have CPR approval with a performance declaration. The marking must be on the packaging or otherwise, not the cable itself.
The requirements for where cables can be used are set by the Directorate for Building Quality (DIBQ). The requirements are outlined in the revision Building Technical Regulations. DIBQ will refer to NEK 400 and NEK 702, and all types of cables that are installed in buildings are covered by the Building Products Ordinance.
The main requirements are:
-
Eca, which are PVC/standard products at today’s safety level
-
Dca s2d2a2 for low-smoke products that are for example used in escape routes
-
If the cables are protected by overhead sprinkles, class Eca will be adequate. The requirements for 50MJ/m cables in escape routes remain unchanged.

CPR requirements for cables
The new scale of classifications goes from A to F. F is the lowest class and meets no requirements (combustible material), and A is the highest class (non-combustible materials). All products used in industry are subject to high standards. The new classifications make it easier to distinguish the properties from each other.
Eca cable
Eca cables provide a basic level of security. All cables, such as ordinary PVC-insulated cables, must at minimum meet the Eca requirement.
NEK 606 - Halogen-free cable
NEK 606 is a technical specification that covers basic requirements for halogen-free cables and/or drilling fluid-resistant cables.
Halogen-free cables are a type of fireproof cable as they provide minimal development of black smoke and corrosive gases. Should a fire occur, the use of halogen-free cables will thus reduce the material damage to electronics and other equipment.
Cables that are particularly suited to maritime environments in the petroleum industry are specified by NEK TS 606.
With NEK 606 as technical specification, you get a selection of cables that satisfy the requirements for mobile and fixed offshore installations. Among other things, NEK TS 606 has stricter requirements and tests for enchanted oil resistance and mud resistance than what other specifications require.
