General Hose and hose assemblies in sizes 3?? and less shall be tested to determine the time to a 20 psi pressure loss in accordance with the method in this section. After the pressure loss@ the sample shall be removed from the radiant heat test apparatus and the leakage rate through the hose shall be determined. 36.1.2 Each color and uniquely striped or marked hose shall be tested. A minimum of 3 hose samples shall be tested to evaluate a hose. All visibly unique surfaces of the hose@ including but not limited to exposed stitching@ striping@ marking as required by Section 37@ and manufacturer??s logos shall be tested. More samples shall be tested as necessary to evaluate all visibly unique surfaces. Once the shortest time to pressure loss from the unique surfaces tested is determined@ a minimum of two additional samples for that surface shall be tested. The results from the surface with the shortest time to pressure loss shall be averaged and reported.
