28、very hose and assemblies, for use on dispensing devices for ammable liquids. A ammable liquid hose assembly consists of exible hose and ttings suitable for attachment to ammable liquid dispensing equipment. For the purpose of this Standard ammable liquids are gasoline and diesel fuel. The term “gaso
29、line” includes gasoline with small amounts of additives such as detergents, solvents for detergents, and anti-icing chemicals and gasoline with up to 15 percent ethanol. 1.2 Hose assemblies are intended for use in accordance with the Automotive and Marine Service Station Code of National Fire Protec
30、tion Association, NFPA 30A. 1.2 revised February 8, 2013 1.3 These requirements cover hose used on dispensing devices for fuels not covered in 1.1 when found by investigation to have the required resistance to these fuels. 1.4 These requirements cover hose and hose assemblies (hose with couplings at
31、tached) in sizes up to and including 1-1/2 inches (38.1 mm). 1.5 Hose for conveying liquid fuel is intended for use at a maximum working pressure of 50 psig (345 kPa). Hose for conveying vapors of fuel is intended for use at a maximum working pressure of 0.5 psig (3.4 kPa), including slight negative
32、 pressures from vapor assist systems. 1.6 These requirements cover hose and hose assemblies for use at temperatures down to minus 40C (minus 40F) or minus 54C (minus 65F). 1.7 These requirements also cover fuel hose assemblies designated as “low permeation”, intended for use on dispensing devices fo
33、r ammable liquids. For the purposes of this standard, permeation is considered to encompass fuel loss through the exible hose, fuel loss at the ttings and fuel loss at the connection between the hose assembly and the equipment to which it is intended to be attached in the dispensing system. 1.8 Thes
34、e requirements do not cover hose or hose assemblies, intended for use in automotive vehicles or in conned areas, except for locations inside the housings of dispensing devices complying with the Standard For Power-Operated Dispensing Devices For Petroleum Products, UL 87.

36、ated value is the requirement. 2.2 Undated references 2.2.1 Any undated reference to a code or standard appearing in the requirements of this standard shall be interpreted as referring to the latest edition of that code or standard. 3 Glossary 3.1 For the purposes of this outline, the following deni
37、tions apply. 3.2 ADJUSTED MASS LOSS The mass loss of the blank (unlled hose assembly) subtracted from the mass loss of a lled hose assembly. The purpose of this is to adjust for factors other than fuel permeation that may affect mass loss. 3.3 BALANCE VAPOR RECOVERY HOSE ASSEMBLY A coaxial hose cons
38、isting of an inner line for conveying fuel and an outer line. Fuel vapors are permitted to return to the fuel dispenser in the annular space between the two lines. 3.3 revised August 23, 2013 3.4 HOSE ASSEMBLY VOLUME (V) The total volume in cubic centimeters of a capped hose assembly, calculated as
39、follows: V=D 2 (L + 2d) p /4 in which: D = the inner diameter of the hose in centimeters, as determined in 15.5.3 L = the length of the hose in centimeters, as determined in 15.5.1 d = the depth of the cap in centimeters, as determined in 15.5.2 3.5 LEAST SQUARES FIT LINE A best t line drawn through
40、 a set of data such that the sum of the squared residuals has its least value, a residual being the difference between an observed value (data point) and the line. 3.6 PERMEATION SURFACE AREA The length of the hose as determined in 15.5.1 multiplied by the inner circumference of the hose, expressed
41、in square meters. For vacuum-assist vapor recovery hose, the length of the hose is multiplied by the inner circumference of the outer hose. For balance vapor recovery hose, the length of the hose is multiplied by the average inner circumference of the outer hose. 3.6.1 REINFORCEMENT Natural or synth
42、etic bers or fabric, or metallic wire that is wrapped, braided or spiral wound in one or more layers over the tube, intended to provide longitudinal and transverse (hoop) strength to the hose. 3.6.1 added August 26, 2011 AUGUST 23, 2013 HOSE AND HOSE ASSEMBLIES FOR DISPENSING FLAMMABLE LIQUIDS - UL

44、e two lines. 3.7 revised August 23, 2013 CONSTRUCTION 4 Tube and Cover 4.1 Single-line hose and double-line vapor recovery hose 4.1.1 The tube shall be made from a material resistant to gasoline and diesel fuel. 4.1.2 The cover shall be made from a material resistant to gasoline, diesel fuel, oils,
45、and ozone. 4.1.3 The tube and cover shall be of uniform thickness, and free from pitting, blisters, or other imperfections. This requirement is not intended to exclude the use of a corrugated cover. 4.2 Coaxial vapor recovery hose 4.2.1 The tube and cover, if any, of the inner hose shall be made fro
46、m materials resistant to gasoline and diesel fuel. 4.2.2 The tube of the outer hose or a homogeneous outer hose shall be made from materials resistant to gasoline and diesel fuel. 4.2.3 The cover of the outer hose or a homogeneous outer hose shall be made from a material resistant to gasoline, diese
47、l fuel, oil, and ozone. An outer homogeneous thermoplastic hose with no separate layer of reinforcement shall also be made from a material resistant to sunlight. 4.2.4 The tube and cover shall be of uniform thickness and free from pitting, blisters, or other imperfections. This requirement is not in
48、tended to exclude the use of a corrugated tube, cover, or outer vapor hose. 5 Thickness of Cover 5.1 The thickness of the cover shall not be less than 0.047 inch (1.19 mm) when measured in accordance with 5.2 5.6. Exception: This requirement does not apply to the cover of the inner hose and the oute
49、r vapor hose of a coaxial type vapor recovery hose. 5.2 For removing irregularities in samples, the buffing machine or skiving machine outlined in the Standard Practice for Rubber Preparation of Product Pieces for Test Purposes from Products, ASTM D3183, is to be used.
