SAE J1527 Marine Fuel Line Hoses AB types class12 style R123

Jul 08, 2019

SAE J1527_201102 specifies requirements of marine fuel hoses for two types, three classes and four styles of reinforced hose and non-reinforced tubing for conveying gasoline or diesel fuel aboard small craft including pleasure craft whose fuel systems are regulated under 33 CFR 183 Sub-part J.

 

Refer to SAE J1942 Hose and Hose Assemblies for commercial marine nonmetallic flexible hose or hose assemblies used in systems on board commercial vessels inspected and certified by the U.S. Coast Guard.

 

Refer to SAE J2046 Personal Watercraft Fuel Systems for fuel hose used on Personal Watercraft.

 

Two types of Hosing meeting 33 CFR 183 Sub-part J requirements with respect to fire resistance:

USCG Type A provide a minimum 2-1/2 min of fire resistivity with no evidence of leakage when subjected to the fire test in paragraph 5.

USCG Type B need not be subjected to the 2-1/2 min fire test.

  

Hose Classifications as per Fuel Resistance and Rate of Permeation.Hose intended for applications such as fuel feed lines where liquid fuel is normally continuously in the hose.

Class 1 and Class 1-15 Hose intended for applications such as fuel tank vent and fill hoses, where liquid fuel is not normally continuously in contact with the hose.

Class 2

 

Hose Styles-Construction has style R1, style R2 and Style R3.

Style R1  embodies a smooth bore fuel and oil resistant tube, reinforced with one or more plies of-textile fiber yarn, cord or fabric, and finished with a suitable oil, ozone, and heat-resistant cover. For Class 1 and Class 1-15 service, covers or sleeves having a lower permeation rate than the tube shall be pinprick ed.

Style R2 embodies a smooth bore fuel and oil resistant tube, a helical wire embedded in the hose, and finished with a suitable oil, ozone, and heat-resistant cover. Plies of fabric or cord may be applied between the tube or cover and the helical wire. The helical wire must not be exposed after the cover is subjected to the abrasion test in paragraph 6.

Style R3 embodies a smooth bore fuel and oil resistant tube, reinforced with one or more braids of wire, and finished with a suitable oil, ozone, and heat-resistant cover. These hoses shall be used with end fittings complying with SAE specification J516-100R5
