32、his standard shall comply with the requirements for that component. 2.1.2 A component is not required to comply with a specic requirement that: a) Involves a feature or characteristic not required in the application of the component in the product covered by this standard, or b) Is superseded by a r

33、equirement in this standard. 2.1.3 A component shall be used in accordance with its rating established for the intended conditions of use. 2.1.4 Specic components are incomplete in construction features or restricted in performance capabilities. Such components are intended for use only under limite

34、d conditions, such as certain temperatures not exceeding specied limits, and shall be used only under those specic conditions. 2.2 Units of measurement 2.2.1 Values stated without parentheses are the requirement. Values in parentheses are explanatory or approximate information. 2.3 Undated reference

36、ION FROM UL 3 Glossary 3.1 For the purpose of this standard, the following denitions apply. 3.2 BLENDING OPTION Dispensing devices may be provided with an option that blends two specic fuels into one fuel to be dispensed. This blending occurs at the dispenser level and can be in two forms: a) Fixed

37、blending Blending at the dispenser level that blends two specic fuels into one fuel to be dispensed, and that fuel to be dispensed is xed. For example, xed blending includes blend options where gasoline and denatured fuel ethanol can be blended to achieve E85, which is the actual dispensed fuel. b)

38、Variable blending Blending at the dispenser level that blends two specic fuels into the fuel to be dispensed, but the fuel to be dispensed can be any of a number of previously set points. For example, variable blending includes blend options where gasoline and E85 can be blended to achieve E40, E60,

39、 and E85 as the actual dispensed fuel. 3.3 FITTING, PIPE-CONNECTING A tting of the threadless compression seal-ring type for use in the assembly of dispensing devices to facilitate connection of piping or tubing. These ttings shall be made in the straight coupling style, as well as in the tee, ell,

40、reducer, adapter, and other styles.

41、RMISSION FROM UL 3.4 FITTING, RECONNECTABLE TYPE An emergency breakaway tting designed such that upon separation it is intended to be reconnected and reused when it is not damaged. 3.5 FITTING, SINGLE-BREAK TYPE An emergency breakaway tting that, upon separation, is not intended to be reconnected an

42、d reused. 3.6 GASOLINE/ETHANOL BLENDS Blended fuels composed of a gasoline component and an ethanol component. The numerical value corresponding to the ethanol component determines the blend rating (such as E85 for 85% ethanol, 15% gasoline). 3.7 HOSE SWIVEL A swivel connector with one end attached

43、to a hose and the other end to an appurtenance. The hose swivel will allow radial movement of the hose and/or appurtenance to prevent the hose from twisting or having torsional stress. 3.8 PRESSURE INDICATING DEVICE As used herein, the pressure indicating device means one of the following: a) An ana

44、log gauge having a pressure range such that the test pressure is between 30 and 70 percent of the maximum scale reading of the gauge; b) A digital pressure transducer, or other digital gauge, that is calibrated over a range of pressure that includes the test pressure; or c) Other device that is equi

45、valent to the devices in (a) or (b). 3.9 SEALS, DYNAMIC A seal that is subject to mechanical movement or other applied forces that result in movement or exing of the seal under normal use conditions. 3.10 SEALS, STATIC A seal that is not subject to mechanical movement or other applied forces other t

46、han compressing forces that are applied during installation, after which, the seal is held in place during normal use conditions. 3.11 SWIVEL CONNECTOR A type of swivel categorized as either a hose swivel or swivel joint. 3.12 SWIVEL JOINT A swivel connector installed in a piping system with at leas

47、t one end attached to a rigid pipe or other appurtenance that is rmly affixed. The swivel joint will allow radial movement of the pipe or other appurtenance attached to the swivel to prevent torsional stress.
