CPR - Frequently Asked Questions

16 May 2017

CPR is the law so you have to conform.

True, it’s a European regulation so we don’t have a choice.

Brexit means CPR won’t apply to us.
False, the British government has already made it law & whatever happens with Brexit this won’t get repealed!

All PVC cables will be banned.
False, PVC can be made flame retardant and is still excellent in the right application. 

Some cables will be banned.
False, class F covers cables that burn too much to meet class E but they can still be used if the building owner or specifier accepts the performance. 

I specify LSHF so I don’t need to do anything.
False. The standard is primarily about the spread of fire and heat release, not the toxicity of gases or smoke given off. So LSHF will be just as relevant in many applications.

Will I need to keep more records?
Yes, you will need to know the class of product you’ve installed for up to ten years. Some cables will be printed but many won’t so the labelling and DoP (Declaration of Performance) will be important, you may be also be asked to pass this on to the specifier or building owner.

Who is responsible for CPR?
The specifier or installer are responsible for the choice of cable as only they know the application and classes needed. The supplier is responsible for ensuring the cable conforms to a given class if the cable is intended for use in a building. 

Are all cables affected?
No, cables not installed within a building or civil works do not need to conform to CPR. Confusingly, fire performance / survival cables, such as Prysmian’s FP100, FP200 and FP600, are not yet covered by CPR  -  although a separate standard is currently being written for these.

Can I buy all the cables I want conforming to CPR? 
No, so far only a small number of cables are compliant. Manufacturers are only likely to test cables that are typically used in buildings, so if the cable is primarily used outdoors or in equipment then it is unlikely to be compliant.
