yes, i am sure

what other specs. are you concerned about anyway? You people get too fanatical about all this FR stuff. We've had ALL the proper testing done on the fabric and we know how to make quality shirts, so don't you worry.
Not to be too fanatical but we are right to question every manufacturer providing arc flash PPE. I will not risk the lives of my workers for a few dollars savings and I certainly do take all my suppliers to task for any quality problems I find with their products.
My site spends well in excess of $500,000 per year on Arc Flash PPE and equipment, corporately the figure is in the millions. I hope your product is high quality because if it hits my desk for review, I will look for any faults it might have - price point is secondary considered with safety.
Good luck!
