4.6 Tests.
4.6.1 Examination. The hose shall be examined to determine that the materials,
interface, end cover, outer covering, weight, identification, and interchangeability conform to
this specification.
4.6.2 Odor. Oxygen shall be flowed through the hose at 10 liters per minute for 2
minutes and then the hose shall be tested for odor in accordance with SAE-AS1065.
4.6.3 Cleanliness. All surfaces shall be free of visible particulates (50 microns and
larger), free of visible fluorinated lubricants, and free of hydrocarbon contamination to a level
not greater than 3 mg/ft2 (see 6.5). Cleanliness of the surfaces shall be demonstrated by
industrially accepted methods and these cleaning and verification methods shall be identified
(see 6.2 and 6.5).
4.6.4 Flexibility. The hose shall be coiled and uncoiled around a 1.75 inch diameter rod
4 times. After each coiling and uncoiling cycle, the hose shall be twisted 90o (in the same
direction each time) about its longitudinal axis. After the 4 coiling cycles, one end of the hose
shall be fixed, the other end shall be twisted 360o in each direction 5 times. The test shall then be
repeated by twisting the opposite hose end. For hoses 30 inches or longer, the hose end shall be
twisted 720o in each direction 5 time. The hose shall then be subjected to the delamination and
leakage tests.
