Groung integrity?

How do I interpret and implement the following client requirement? "Equipment operating at 240v must be checked for ground integrity only." Thanks. George

That sentence does not make sense to me. It might help if I knew the context (as in the sentence before it, or the sentence that established a requirement to which this is an exception). Can you provide some more information?

Ground integrity - Pt. 2

Additional context ...
***
Is there documentation that both the laboratory director and the institutional safety committee have approved a program to ensure that all laboratory instruments and appliances are adequately grounded and checked for current leakage before initial use, after repair or modification, and when a problem is suspected?
NOTE: Exceptions to these requirements are as follows:
- Devices protected by an approved system of double insulation or its equivalent. Such devices must be distinctively marked
- Equipment operating at 240 v must be checked for ground integrity only
In addition, the U.S. Occupational Safety and Health Administration (OSHA) requires that power cords of portable electrical equipment be visually inspected for external defects whenever relocated. Grounding configurations may not be bypassed by, for example, an adapter that interrupts the continuity of the grounding.

We are specifically looking for criteria to determine what acceptable ground integrity is for equipment operating at 240v. I am not sure if I am correct, but I think that the acceptable ground integrity would vary by the type of instrument and the amps that the equipment draws.
Last - how do I put "ground integrity" into layman's terms?
 
Not sure what the wording means or has any clue how they wanted it tested, but I know how to test the ground integrity.

1 is with a load box designed to induce a 6X fault between L-L, and L-G.

Another home brew method is to use a 120 VAC lamp connected between each L-G, measure current and voltage before and after loaded to determine the impedance of the EGC.
 
Current leakage could be checked by plugging the instrument into a GFCI cord then plugging the cord into an outlet. If the GFCI trips, the instrument is leaking current.

As for ground continuity, I'd be inclined to visually inspect for any obvious problems, and then check resistance between G and N.

Write up a procedure and get a form made up to record the results. Thats all they probably really care about. If you can drag the procedure to about 6 or 7 pages that is best. Ask the lab director to review it and add his name to the "reviewed by" column on the title page. Filling in the form will take more time than the actual checks.
