Myth – CPR is no longer important
The requirement for cables to be CPR tested, classified and certified became mandatory in the UK in July 2017, and that legal requirement remains in place today.

The world of cable is, at best, convoluted and, at worst, a massive can of writhing, slippery worms. It’s full of obscure acronyms and complicated standards, so it’s not surprising that, over time, a number of misconceptions have woven their way into the fabric of this vitally important sector of the construction industry. Part 2 in our series of cable myths focuses on LSF and LSHF and if it really matters which you use.

It’s full of obscure acronyms and complicated standards, so it’s not surprising that, over time, a number of misconceptions have woven their way into the fabric of this vitally important sector of the construction industry. Probably the one I hear most often is: 'if it's not BASEC approved you can't use it'
Although there are some exceptions, generally speaking it is illegal to install any cable that was placed on the market on or after 1st July 2017 that is not CPR compliant. We believe that CPR class CCA is destined to become the benchmark for many commercial installations in the UK. It provides the benefits of reduced reaction to fire in tandem with the robust verification process of System 1+.
On July 1st 2017 a new and mandatory ruling with respect to making a cable’s fire related properties publically available came into force, but rather than diving straight into the specifics it may be more useful to start with something of an overview of how and why it came to be. The burning question (no pun intended) has to be whether there will be an immediate impact on the UK’s construction industry?
Do you know the difference between LSF and LSHF cable? There is a worryingly common misconception that LSF cable (Low Smoke and Fume) and LSHF cable (Low smoke Halogen Free) are simply different names for the same thing.
