For engineers: how do I test melamine quality

Here’s the background:
I am working on a development project in Iraq and I think a contractor is ripping us off.

If I can get samples of the particle board (melamine) he is using for furniture, is it possible to test it for quality? Are there different grades of melamine?

If I can get a sample back to the US what kind of firm could do this testing? What kind of company would I look for in the Yellow Pages?

I’d really appreciate any info someone might have. This project is for the school children of Iraq and I’m just trying to do a good job here, but I’m not an engineer.

Here is the main worldwide manuf for melamine
Here is the page with the spec sheets and for performance data for both grades of melamine along with the product quality contact info at the bottom

Thanks! I didn’t even have a clue where to start, then I thought of the SDMB and voila.
