1/ If it is necessary to cut the hose assembly to perform this test, perform this test on one additional
sample and not on samples 1, 2, 3, 4 or 9 and 10. This may occur if a specific configuration is
required because of an OEM drawing. If doing hose inspections only use a hose assembly
configuration that does not require it to be cut.

certificate stating that each lot has been sampled, tested, and inspected in accordance with
