26、ION FROM UL INTRODUCTION 1 Scope 1.1 These requirements cover foam producing equipment and liquid concentrates employed for the production and discharge of foam that has an expansion ratio of 20:1 or less and is used for re extinguishment. These requirements are based on the premise that foam equipm
27、ent and specied types of foam liquid concentrates with which they are intended to be used are to be investigated for use with each other. 1.2 If foam equipment covered by these requirements incorporate sprinklers, the sprinklers shall comply with the Standard for Automatic Sprinklers for Fire Protec
28、tion Service, UL 199. 1.3 Requirements for the installation and use of foam equipment and liquid concentrates are included in the following standards of the National Fire Protection Association: a) Low Expansion Foam and Combined Agent Systems, NFPA 11; b) Deluge Foam-Water Sprinkler and Spray Syste
29、ms, NFPA 16; c) Installation of Closed-Head Foam-Water Sprinkler Systems, NFPA 16A. 1.4 A product that contains features, characteristics, components, materials, or systems new or different from those covered by the requirements in this standard, and that involves a risk of re, electric shock, or in
30、jury to persons shall be evaluated using the appropriate additional component and end-product requirements to determine that the level of safety as originally anticipated by the intent of this standard is maintained. A product whose features, characteristics, components, materials, or systems conict
31、 with specic requirements or provisions of this standard shall not be judged to comply with this standard. Where appropriate, revision of requirements shall be proposed and adopted in conformance with the methods employed for development, revision, and implementation of this standard. 1.4 revised Se
32、ptember 8, 1999 2 General 2.1 Units of measurement 2.1.1 If a value for measurement is followed by a value in other units in parentheses, the second value may be only approximate. The rst stated value is the requirement. 2.2 Components 2.2.1 Except as indicated in 2.2.2, a component of a product cov
33、ered by this standard shall comply with the requirements for that component. 2.2.2 A component need not comply with a specic requirement that: a) Involves a feature or characteristic not needed in the application of the component in the product covered by this standard, or b) Is superseded by a requ
34、irement in this standard. SEPTEMBER 8, 1999 FOAM EQUIPMENT AND LIQUID CONCENTRATES - UL 162 5UL COPYRIGHTED MATERIAL NOT AUTHORIZED FOR FURTHER REPRODUCTION OR DISTRIBUTION WITHOUT PERMISSION FROM UL 2.2.3 A component shall be used in accordance with its recognized rating established for the intende
35、d conditions of use. 2.2.4 Specic components are recognized as being 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 un
36、der those specic conditions for which they have been recognized. 2.3 Undated references 2.3.1 Deleted September 8, 1999 3 Glossary 3.1 For the purpose of this standard, the following denitions apply. 3.2 CLASS B FIRES Fires in ammable and combustible liquids, gases, and greases. 3.3 CONTROL A reduct
37、ion in re intensity of approximately 90 percent. 3.4 DISCHARGE COEFFICIENT K Coefficient of discharge in the formula: where: Q = Flow in gallons per minute (L/s x 15.85), p = Pressure in psi (6.89 kPa) 3.5 DISCHARGE DEVICE Fixed, semixed, or portable devices, such as foam chambers, xed foam makers,
38、monitors, nozzles, spray nozzles, and sprinklers, that direct the ow to the re or ammable liquid surface. 3.6 FIRE TEST PAN The re test pan is to be square, straight sided, with a minimum area of 50 square feet (4.65 m 2 ). The pan is to be of steel not less than 1/4 inch (6.4 mm) thick with liquid
39、tight welded joints and provided with 3/16 inch (4.8 mm) thick angle to reinforce the upper edge. The reinforcement is to be continuous around the perimeter of the pan and is to form a turned-out edge ush with the top edge of the pan. The top edge surface so formed is to be 1-3/4 inch (44 mm). The r
40、einforcing angle is to be continuously welded to the outside of the pan at the top edge and tackwelded at the edge of the lower lip of the angle.

41、 PERMISSION FROM UL 3.7 FILM FORMING LIQUID CONCENTRATE A foam solution that has a spreading coefficient greater than zero when tested in accordance with the Film Forming Test, Section 6. 3.7 effective July 6, 1995 3.8 FIXED FOAM MAKER A device that generates foam and that is intended to be installe
42、d between the supply piping of foam solution and piping leading to discharge outlets. 3.9 FOAM A re ghting agent made by mechanically mixing air with a solution consisting of fresh or salt water to which a foam liquid concentrate has been added. 3.10 FOAM CHAMBER A device that: a) May include an int
43、egral foam maker, b) Is intended for xed installation on ammable or combustible liquid storage tanks, and c) Produces foam and introduces it into the storage tanks. 3.11 FOAM EXPANSION VALUE The ratio of nal foam volume to original foam solution volume before adding air. 3.12 FOAM QUALITY A measure
44、of a foams physical characteristics, expressed as the foams: a) 25 percent drain time, and b) Expansion value. 3.13 FOAM SOLUTION A mixture of a proportioned or premixed foam liquid concentrate dissolved in either fresh or salt water. 3.14 FULL-SCALE EQUIPMENT Field installed components, such as pro
45、portioners and foam makers, that are intended to extinguish res. 3.15 INDUCTION A method that uses the venturi principle to introduce a proportionate quantity of foam concentrate into a water stream. a) Pressure Induction This method employs the water supply to pressurize the foam concentrate storag
46、e tank. At the same time, water owing through an adjacent venturi or orice creates a pressure differential. The difference between the water supply pressure and this lower pressure area forces the foam concentrate to ow through a xed or metering orice into the water stream. b) Vacuum Induction This
47、method utilizes the negative pressure created by water passing through a venturi to draw the liquid concentrate from the storage tank or container through a pick-up tube and mix it with the water stream. c) Pump-and-Motor Induction By means of an auxiliary pump, foam compound is injected into the wa
48、ter stream passing through an inductor. The resulting foam solution is then delivered to a foam maker. The proportioner may be inserted in the line at any point between the water source and foam maker. MARCH 30, 1994 FOAM EQUIPMENT AND LIQUID CONCENTRATES - UL 162 7UL COPYRIGHTED MATERIAL NOT AUTHOR
