22、RIAL NOT AUTHORIZED FOR FURTHER REPRODUCTION OR DISTRIBUTION WITHOUT PERMISSION 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
23、extinguishment. These requirements are based on the premise that foam equipment 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 sprink
24、lers shall comply with the Standard for Automatic Sprinklers for Fire Protection 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 Com
25、bined Agent Systems, NFPA 11; b) Deluge Foam-Water Sprinkler and Spray Systems, NFPA 16; c) Installation of Closed-Head Foam-Water Sprinkler Systems, NFPA 16A. 2 Units of measurement 2.1 If a value for measurement is followed by a value in other units in parentheses, the second value may be only app
26、roximate. The rst stated value is the requirement. 3 Components 3.1 Except as indicated in 3.2, a component of a product covered by this standard shall comply with the requirements for that component. 3.2 A component need not comply with a specic requirement that: a) Involves a feature or characteri
27、stic not needed in the application of the component in the product covered by this standard, or b) Is superseded by a requirement in this standard. 3.3 A component shall be used in accordance with its recognized rating established for the intended conditions of use. 3.4 Specic components are recogni
28、zed 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 under those specic conditions for which they have been rec
29、ognized. FEBRUARY 23, 2018 FOAM EQUIPMENT AND LIQUID CONCENTRATES - UL 162 5UL COPYRIGHTED MATERIAL NOT AUTHORIZED FOR FURTHER REPRODUCTION OR DISTRIBUTION WITHOUT PERMISSION FROM UL 4 Glossary 4.1 For the purpose of this standard, the following denitions apply. 4.2 CLASS B FIRES Fires in ammable an
30、d combustible liquids, gases, and greases. 4.3 CONTROL A reduction in re intensity of approximately 90 percent. 4.4 DISCHARGE COEFFICIENT K Coefficient of discharge in the formula: where: Q is Flow in gallons per minute (L/s x 15.85), p is Pressure in psi (6.89 kPa) 4.5 DISCHARGE DEVICE Fixed, semix
31、ed, or portable devices, such as foam chambers, xed foam makers, monitors, nozzles, spray nozzles, and sprinklers, that direct the ow to the re or ammable liquid surface. 4.6 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
32、to be of steel not less than 1/4 inch (6.4 mm) thick with liquid 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.
33、The top edge surface so formed is to be 1-3/4 inch (44 mm). The reinforcing 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. 4.7 FILM FORMING LIQUID CONCENTRATE A foam solution that has a spreading coefficient grea
34、ter than zero when tested in accordance with the Film Forming Test, Section 7. 4.8 FIXED FOAM MAKER A device that generates foam and that is intended to be installed between the supply piping of foam solution and piping leading to discharge outlets. 4.9 FOAM A re ghting agent made by mechanically mi
35、xing air with a solution consisting of fresh or salt water to which a foam liquid concentrate has been added. 4.10 FOAM CHAMBER A device that: a) May include an integral foam maker, b) Is intended for xed installation on ammable or combustible liquid storage tanks, and c) Produces foam and introduce
36、s it into the storage tanks. FEBRUARY 23, 2018 FOAM EQUIPMENT AND LIQUID CONCENTRATES - UL 162 6UL COPYRIGHTED MATERIAL NOT AUTHORIZED FOR FURTHER REPRODUCTION OR DISTRIBUTION WITHOUT PERMISSION FROM UL 4.11 FOAM EXPANSION VALUE The ratio of nal foam volume to original foam solution volume before ad
37、ding air. 4.12 FOAM QUALITY A measure of a foams physical characteristics, expressed as the foams: a) 25 percent drain time, and b) Expansion value. 4.13 FOAM SOLUTION A mixture of a proportioned or premixed foam liquid concentrate dissolved in either fresh or salt water. 4.14 FULL-SCALE EQUIPMENT F
38、ield installed components, such as proportioners and foam makers, that are intended to extinguish res. 4.15 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
39、pressurize the foam concentrate storage 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 w
40、ater stream. b) Vacuum Induction This 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,
41、 foam compound is injected into the water 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. 4.16 LIQUID CONCENTRATE A protein or synthetic based liquid
42、that is intended to be diluted with fresh water, salt water, or a mixture of both fresh and salt water to a concentration (volume of concentrate/volume of water) of 1 percent or higher. Different types of low expansion liquid concentrates are designated as follows: a) Aqueous Film Forming (AFFF) A l
43、iquid concentrate that has a uorinated surfactant base plus stabilizing additives. b) Protein A liquid concentrate that has a hydrolyzed protein base plus stabilizing additives. c) Fluoroprotein A liquid concentrate that is similar to protein, but with one or more uorinated surfactant additives. d)
44、Film Forming Fluoroprotein (FFFP) A liquid concentrate that has both a hydrolyzed protein and uorinated surfactant base plus stabilizing additives. e) Synthetic A liquid concentrate that has a base other than uorinated surfactant or hydrolyzed protein.
