"I would like anyone on this post to explain how they intend to test a mobile phone charger?"
Depending on the connector, a test could be possible. Many chargers, such as Nokia-style ones, have barrel plugs, which would count as 'exposed conductive parts'. So therefore, that is where you could clip your test lead, and perform a Class II Insulation Resistance test, or a Class II Substitute Leakage test, or a Class II Touch Current test.
Obviously, if the charger had a connector that no exposed conductors, then these tests would not be possible.
*Any electrical tests should only be performed after the appliance has passed a visual inspection*
"... only a moulded transformer..."
Not always moulded. Sealed: yes, mostly, but some still with empty space inside. Internal components can become dislodged, depending on the amount of abuse that charger has taken. I have seen Class II chargers, and other similar plug-in power adaptors, pass a visual, but fail an insulation test because if this (none of us have X-ray vision!).
"Conclusion - You do not PAT test mobile phone chargers - visual only."
Well, no. In some situations, the electrical tests may be considered to not be required. Other situations they may be needed. It all depends on the conclusions of the RA that has been carried out.
My main point being that you CAN perform electrical tests on (some) phone chargers, if neccessary.
"The actual document that needs to be consulted is the IEE code of practice for in service inspection and testing of electrical equipment which clearly states on page 13 ALL class 2 equipment in hotels, offices and shops only needs a formal visual inspection every 24 months, no Combined inspection is required."
The table in the IEE CoP that you refer to is 'Suggested Initial Frequency of Inspection & Testing of Equipment'. Notice the words 'suggested' and 'initial'.
It also clearly states that intervals between checks, inspections & tests must be kept under review, particularly until patterns of failure/damage, if any, are determined, which also ties in with the RA.
So yes, in general terms, Class II equipment in most hotels, offices & shops may not need testing, just visual inpections. But this doesn't mean there won't be exceptions, which should be identified through assessment. And if the assessment requires it, most Class II appliances can be electrically tested, or 'PAT tested'.
