NRC stands for Noise Reduction Coefficient. This is a standard and commonly used method to calculate the ratings of the ASTM C423 test on noise reduction foam. This method covers frequencies between 125 and 4000HZ. The higher the NRC rating, the more sound the material can absorb. All Noise Studio Control foam is a California 117 flame retardant specifications, class B type. Fire resistant/retardant is a test that calculates "Flame Spread Index", and "Smoke Developed Index". These numbers determine whether the material is "Class A", "Class B", or "Class C". Class A tells that the material will not burn or smoke much, and Class C represents that the material will burn heavily and produce even more smoke. Class B will burn a little more than Class A, and also produce slightly more smoke than in Class A. | |||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
