Dear colleagues. I have submitted a product for CB certification to IEC/EN/UL 60065. The product is powered from a 12V dc wall wart purchased from an external supplier. The power supply is fully CB approved to IEC/EN/UL 60950 and operated well within its ratings. I submitted the CB documentation for the power supply along with the product to the safety testing agency. I am surprised that the testing agency decided to dismantle the power supply and thoroughly evaluate it even though it is already pre-approved. Is this usual and if so why bother with a pre-approved power supply if you are going to be paying for it to be tested along with your product?
Your knowledge and experience would be appreciated. Many thanks in advance. Ian McBurney Design & Compliance Engineer. Allen & Heath Ltd. Kernick Industrial Estate, Penryn, Cornwall. TR10 9LU.
