26、 These requirements cover hose and hose assemblies, including vapor recovery 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 th
27、is Standard ammable liquids are gasoline and diesel fuel. The term “gasoline” includes gasoline with small amounts of additives such as detergents, solvents for detergents, and anti-icing chemicals and gasoline with up to 10 percent ethanol. 1.2 Hose assemblies are intended for use in accordance wit
28、h the Automotive and Marine Service Station Code of National Fire Protection Association, NFPA 30A. 1.3 These requirements cover hose and hose assemblies (hose with couplings attached) in sizes up to and including 1-1/2 inches (38.1 mm). 1.4 Hose for conveying liquid fuel is intended for use at a ma
29、ximum 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 pressures from vapor assist systems. 1.5 These requirements cover hose and hose assemblies for use at temperatures down to
30、 minus 40C (minus 40F) or minus 54C (minus 65F). 1.6 These requirements also cover fuel hose assemblies designated as “low permeation”, intended for use on dispensing devices for ammable liquids. For the purposes of this standard, permeation is considered to encompass fuel loss through the exible ho
31、se, 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. 1.7 These requirements do not cover hose or hose assemblies, intended for use in automotive vehicles or in conned areas, except for
32、 locations inside the housings of dispensing devices complying with the Standard For Power-Operated Dispensing Devices For Petroleum Products, UL 87. 2 General 2.1 Units of measurements 2.1.1 When a value for measurement is followed by a value in other units in parentheses, the rst stated value is t
33、he requirement.

34、rements 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 denitions apply. 3.2 ADJUSTED MASS LOSS The mass loss of the blank (unlled hose assembly) subtracted from the mass loss of a lled
35、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 consisting of an inner line for conveying fuel and an outer line. Fuel vapors are permitted to return to the fuel dispenser in the
36、 annular space between the two lines. 3.4 HOSE ASSEMBLY VOLUME (V) The total volume in cubic centimeters of a capped hose assembly, calculated as follows: V=D 2 (L + 2d) /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,
37、 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 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 th
38、e 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 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 vapo
39、r recovery hose, the length of the hose is multiplied by the average inner circumference of the outer hose. 3.7 REINFORCEMENT Natural or synthetic 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 trans
40、verse (hoop) strength to the hose. 3.8 VACUUMASSIST VAPOR RECOVERY HOSE ASSEMBLY A coaxial hose consisting of an inner vacuum line for vapor recovery and an outer line. Fuel is dispensed through the annular space between the two lines. JUNE 30, 2017 HOSE AND HOSE ASSEMBLIES FOR DISPENSING FLAMMABLE

42、2 The cover shall be made from a material resistant to gasoline, diesel fuel, oils, 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
43、 recovery hose 4.2.1 The tube and cover, if any, of the inner hose shall be made from 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
44、 a homogeneous outer hose shall be made from a material resistant to gasoline, diesel 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
45、 and free from pitting, blisters, or other imperfections. This requirement is not intended 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. Ex
46、ception: This requirement does not apply to the cover of the inner hose and the outer 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 Te
47、st Purposes from Products, ASTM D3183, is to be used. 5.3 The abrasive wheel of the buffing machine is to be No. 30 60 grit and the diameter and rotary velocity of the wheel are to be such that it will have a peripheral speed of 4000 700 feet per minute (20.3 3.6 m/s). The machine is to be provided
48、with a slow feed so that very little compound can be removed at one cut to avoid overheating of the specimen.

49、.4 A dial micrometer graduated to 0.001 inch (0.03 mm) that exerts a load of 2.82 3.00 ounces (80 85 grams) by means of a weight is to be used to measure thickness. The load is to be applied through a at contact foot 0.25 0.01 inch (6.4 0.3 mm) in diameter. 5.5 To determine the thickness of the tube and cover, a strip,68inches (152.4 203.2 mm) long and 1 inch (25.4 mm) wide, or as close to 1 inch (25.4 mm) as possible from small diameter hose, is to be cut longitudinally
