Title: Flexible hoose.pdf
PRESSURE CYCLINGSamples of Model ASH15-2025 flexible sprinkler hose in lengths of 27.6 and 39.4 in. (700 and 1000 mm), considered representative of all sprinkler hose discussed in this Report, were subjected to 20,000 cycles of pressure varying from 0 psi to 175 psi (0 to 1205 kPa). During this test the samples were bent in a 90º angle at their minimum bend radius of 8 inches (203 mm). After completingPage 4 of 83.43.5FM APPROVALS Project ID: 304745720,000 cycles, the hoses were hydrostatically pressurized to 700 psi (4830 kPa) for a period of five minutes. There was no failure or visible damage to the samples as a result of this test. These results are deemed satisfactory.VACUUM TEST
