What are you trying to accomplish in the end?

We use a cotton blend non-ESD glove. A top memeber of our global management team suggested we change ESD gloves. However our local management team does not agree and want to back their opinion up with some data. I've been tasked with gathering that data.

Have you established a threshold damage level?  What amount of damage do you induce above that level?  

How much product are are you losing from ESD damage?  How many product returns are traced to latent ESD damage?

Are your workbenches and surfaces already ESD guarded?  

The simplest answer is that if you are not losing any product, then there is no immediate damage, although there might be latent damage.

If you are already losing product, then it would seem to be prudent to use proper gloves.

As I stated earlier this task was a request of my supervisor. I have no choice but perform the test. Management has the answers to the question in the post above but still want the test done. This is just a battle between two of our "chiefs" and us little indians all have to suffer.

Well, the simplest thing you can do is to use what you probably already have, somewhere; ESD field meters.  

Place them in the environment and compare the readings with and without the ESD gloves.
