Positive Pressure UBC 7-2 (1997) Part 1
UBC 7-2 (1997) designates that the product has been positive pressure tested to the new standard. Part I of this symbol designates the fire test. Since this symbol is used to designate the positive pressure fire test and does not differentiate between categories "G" and "J", additional information is needed. Products intended for use as edge sealing systems needs to be labeled as such or list category "G" in their literature. Without this information, the product is category "J"; fire tested to the new standard of positive pressure.

These products are no greater than 1/2" (12.7 mm) in height and have no more than 1/4" (6.3 mm) vertical rise or with slop proportions no greater than 1:2 slope.
