Hi,

I am questioning about the second option, mesuring the contaminant levels.

The table p 462 is indicating level to respect. but in front of each specific contaminant, there is also EPA and ISO method.

Do we have to comply with the three of them, or are those alternative methods to the maximum concentration.

We are actually consulting a supplyer in order to get the right material to effect mesurement. How to deal with those two others method (iso and epa)?

Also, Would you have any list of suppliers who could work overseas, may be in France, to provide us with adequat material?

Thanks for all,

Véronique
