Posted By Ian Stone Ive been told by our electricians that they dont contain an earth pin so cant be tested (?) they still inspect the lead and signs of damage, just dont plug it into the tester Hope this helps Ian

Posted By john ridley Not sure if there is any specific requirement regarding mobile phones but they would certainly fall under the general category of portable electrical appliance e.g plug & socket arrangement. When conducting PAT, we used to work to the earth return circuit not being tested because there is no earth pin or conductive chassis to connect to. The insulation resistance check of a minimum value of 1M Ohm also cannot be done if there is no chassis to connect to. The only checks that can be conducted is an integrity test of the internal connections inside the plug, correct fuse value as well as a visual check of the cable and the physical state of the transformer unit although this would not appear to be practicable in the case of a mobilephone charger.

Posted By Chris Turner They can be tested, they are a Class 2, appliance as they are probably double insulated and therefore they can be tested for insulation resistance. Whether you go this far is up to you. I would guess that a visual by a competent person would be good enough.
