Flex cord with 2 plug vs 3 plug question

[JohnSTI]

Trying to interpret 1910.334(a)(3)(i)

"A flexible cord used with grounding type equipment shall contain an equipment grounding conductor."

I have a test bench that came with a built in "power strip" which is grounded to the bench, the bench is plugged into the wall outlet (3 prong), which has a ground (internal to the cable) that runs back to the breaker panel.

If I plug a device that only has 2 prongs into the "power strip" on the bench am I violating the above regulation. Or if the 2 prong connector on the flex cord has or doesn't have polarizing prongs does this make a difference?

What I'm looking for is an explanation like this; "if your test bench is grounded (by an individual grounding conductor) any device connected to it needs to be grounded meaning it must have a GND pin (3 prong) in the connector found at the end of the flex cord of the device." to comply with 1910.334(a)(3)(i)

or would 1910.302(b)(1) Requirements applicable to all installations. apply here?

Thanks
