MIL-DTL-17505 Hose And Hose Assembly, Rubber, Oil And Gasoline, Suction And DischargeThis specification covers smooth-bore hose and hose assemblies for suction and discharge service in the transfer of fuels, such as Navy special fuel oil, diesel fuel, oil, jet fuel \(JP-5 or JP-8\), motor gasoline, and aviation gasoline. The hose is intended to handle petroleum products having an aromatic content no greater than 30 percent. The maximum working pressure of this hose is 150 pound-force per square inch \(psi\) \(1 034 kilopascal \(kPa\)\).

MIL-DTL-17505F

4.4 Component and material inspection. Components and materials shall be inspected in

accordance with all the requirements specified herein and in applicable referenced documents.

4.5 Sampling. Sampling and inspection procedures shall be in accordance with ANSI Z1.4. All

hose and hose assemblies of the same type and size offered for delivery at one time shall be

considered a lot for the purpose of inspection.

4.5.1 Sampling for examination. Guidance for inspection level and an Acceptance Quality Level

(AQL) is provided in 6.6.1.

4.5.2 Sampling for tests.

4.5.2.1 Sampling for length, inside diameter, resistance to vacuum, minimum bend and kink

test. Guidance for inspection level and AQL is provided in 6.6.2.

4.5.2.2 Sampling for hydrostatic and electrical conductivity tests. All hose submitted shall be

subjected to the hydrostatic and electrical conductivity tests specified in 4.7.5.

4.5.2.3 Sample for adhesion tests. A 2-foot (610 mm) length of hose identical to the hose

submitted for the lot, except that it shall be without helix wire and nipples, shall be submitted for

the adhesion tests specified in 4.7.14 and 4.7.15.

4.5.2.4 Sample for wire tests. The manufacturer shall submit 6 feet (1 829 mm) of wire taken

from the same lot of wire used in the manufacture of the hose submitted for the tensile strength

and flexibility test specified in 4.7.18.

4.5.2.5 Sample for physical tests. An 8-foot (2 438 mm) length of hose with couplings identical

to the hose submitted for the lot shall be submitted for the burst test specified in 4.7.7. At the

completion of the burst test, additional tests shall be conducted as specified in 4.7.3, 4.7.9 through

4.7.13, 4.7.16, and 4.7.17 on an undamaged section of the 8-foot (2 438 mm) sample of hose

submitted for the burst test.

4.6 Examination. Each of the sample hose lengths selected shall be visually and dimensionally

examined to determine conformance with all the requirements of this specification not involving

tests. The classification of defects in FED-STD-162 shall be used to determine and evaluate

defects through visual inspection. In addition to the defects listed in FED-STD-162, the hose

sample shall be examined for the following defect: (Minor) Marking not as specified (see 3.14).

4.7 Tests.

4.7.1 Length. Hose selected shall be measured for length including fittings (see 3.3).

4.7.2 Inside diameter. Hose selected shall have the id measured in accordance with

ASTM D 380 to determine conformance to table II.
