Class 1 appliance with no exposed metal work to connect test lead too

OK 3rd problem class one appliance with no exposed metal work to connect test lead too how can I carry out the earth bond test given it is a class 1 appliance and not a class 2 appliance like this
A medical physics department in a hospital refers to such devices as plastic class 1. They have this category programmed into their electrical safety testers. It is the same type of test for a class 1 as it measures leakage current from live to earth, but it omits the earth to casing resistance test.
If a plastic class 1 device has a removable mains cable then it's possible to test it as a class 1 by removing the mains cable and carrying out the earth resistance test on just the mains cable, then reconnecting the mains cable to the device for the remainder of the test.
