33、ecic 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or characteristic not required in the application of the component in the product covered by this standard, or b) Is superseded by a requirement in this standard. 2.1.3 A component shall be used in accordance with its rating established for the intended c
34、onditions 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 limited conditions, such as certain temperatures not exceeding specied limits, and shall be used only under those specic condit
35、ions. 2.1.5 A hose nozzle valve with an integral swivel shall be additionally evaluated to the Electrical-Continuity and Operation Tests in the Standard for Emergency Breakaway Fittings, Swivel Connectors and Pipe-Connection Fittings for Diesel Fuel, Biodiesel Fuel, Diesel/Biodiesel Blends with Nomi
36、nal Biodiesel Concentrations up to 20 Percent (B20), Kerosene, and Fuel Oil, UL 567B. The force is to be applied at the point on the swivel farthest from the joint. When necessitated by the swivel construction, this test is to be conducted on additional samples of the swivel with the load applied on
37、 the opposite side of the plane of rotation. See UL 567B, Figures 16.1 16.3 for examples. 2.2 Units of measurement 2.2.1 Values stated without parentheses are the requirement.

39、e purpose of this standard, the following denitions apply. 3.2 DIESEL/BIODIESEL BLENDS Blended fuels composed of a diesel component and a biodiesel component. The numerical value corresponding to the biodiesel component determines the blend rating (such as B20 for 20% biodiesel, 80% diesel). 3.3 HOS
40、E NOZZLE VALVE, AUTOMATIC A hose nozzle valve which is held open during the entire lling operation. It may be held open by manual force or by an integral hold-open or latching device. It incorporates a mechanism that shuts off the ow of liquid during refueling operations to prevent overow from the l
41、l opening when liquid reaches a predetermined point on the spout. 3.4 HOSE NOZZLE VALVES A self-closing device designed to control the ow of ammable and combustible liquids at an operating pressure of minimum 50 psi (345 kPa). It is intended for use at the outlet end of a hose for dispensing ammable
42、 liquids. 3.5 HOSE NOZZLE VALVE, MANUALLY OPERATED A hose nozzle valve that is manually held open during the entire lling operation and closes only upon release of the manual force. 3.6 HOSE NOZZLE VALVE, VAPOR RECOVERY A system constructed to capture vapors displaced during lling operations. The va
43、pors are not processed during the course of this activity. a) Assist Nozzle A vacuum or pump is used to draw the vapors back to tank. b) Balance Nozzle Displacement of vapors from tank being ll forces the vapor back into the storage tank. 3.7 SEALS, DYNAMIC A seal that is subject to mechanical movem
