BASEC also purchases a range of products from the open market to check conformity. End users also approach BASEC when they experience problems with cable they have purchased. On testing, many of these are found not to comply with British Standards, and some could be considered as dangerous.
Dr Jeremy Hodge, Chief Executive of BASEC, said: "Non-compliant cables may cause problems for installers during installation, or suffer reduced life expectancy. Worryingly, we are seeing more examples of cables which could be a danger to end users either through electrocution or fire."
One recent example discovered by BASEC while 'mystery shopping' was a cable claiming to be a heat resistance flex - commonly used in lighting applications. On heat ageing both the insulation on the live core and the sheathing material became brittle. In use, this could result in a short circuit, fire or electrocution.
Another example recently brought to BASEC's attention is a 'fire performance cable' claiming to comply with BS 5839-1 requirements. Testing revealed very poor fire performance, and conductors made of aluminium. BASEC assessors are still dealing with the case.
Dr Hodge said: "This is a classic example where an unscrupulous manufacturer has deliberately made a cable looking like the real thing but without the required characteristics. This cable is dangerous and if installed it needs to be removed and replaced urgently.
"We are still tracking down the origin of this cable and don't know yet where it might have been installed, but it is on the worldwide market. Finding where such cables come from can be difficult, particularly as they often come from overseas."
Specifiers and end users are encouraged to always ask for BASEC approved cable, to check for the 'BASEC' marking, and to report any suspicious cable.
