Stc rating testing
WebThe higher the STC rating, the better the parti-tion is at stopping airborne noise. Under field (F) conditions the measured FSTC rating is about five points lower than the laboratory rating, and this difference is acknowledged in the building codes. Thus if an STC 50 is the required laboratory rating, a field test of 45 is equivalent. In ... WebCEMCO’s Sure-Span Floor Joist System has been tested for STC and IIC ratings.
