11、HOUT PERMISSION FROM ULINTRODUCTION1 Scope1.1 These requirements cover foam liquid concentrates, proportioning equipment, and dischargingequipment for producing foam intended for fire extinguishment or control. For medium-expansion foam,the expansion ratio is 20:1 to 200:1. For high-expansion foam,
12、the expansion ratio is 200:1 toapproximately 1000:1. These requirements are based on the premise that a specific foam liquidconcentrate shall be investigated for use with the intended foam equipment.1.2 Requirements for the design, installation, operation, testing, and maintenance of foam systems fo
13、r fireprotection are included in the Standard for Low-, Medium-, and High-Expansion Foam, NFPA 11.2 Components2.1 Except as indicated in 2.2, a component of a product covered by this Outline of Investigation shallcomply with the requirements for that component.2.2 A component is not required to comp
14、ly with a specific requirement that:a) Involves a feature or characteristic not required in the application of the component in theproduct covered by this Outline of Investigation; orb) Is superseded by a requirement in this Outline of Investigation.2.3 A component shall be used in accordance with i
15、ts rating established for the intended conditions ofuse.2.4 Specific 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 notexceeding specified limits, and shall
16、be used only under those specific conditions for which they havebeen recognized.3 Units of Measurement3.1 Values stated without parentheses are the requirement. Values in parentheses are explanatory orapproximate information.MARCH 13, 2018 UL 139 5UL COPYRIGHTED MATERIAL NOT AUTHORIZED FOR FURTHER R

19、quipment that is installed in a fixedposition and is not mobile.5.4 FOAM A fire fighting agent made by mechanically mixing air with a solution consisting of fresh orsalt water to which a foam liquid concentrate has been added.5.5 FOAM BREAKDOWN The diminishing effect produced on foam by water discha
20、rged fromsprinklers.5.6 FOAM BREAKDOWN CONSTANT An empirically determined constant used to calculate therate, in cubic feet per minute, at which foam is diminished by sprinkler water discharge. This constant isexpressed as feet to the fifth power per gallon.5.7 FOAM CAPACITY The foam volume, in cubi
21、c feet per minute, produced with the intended foamgenerator operating at an inlet pressure while flowing a specific foam solution.5.8 FOAM CONCENTRATION The percent of foam liquid concentrate contained in a foam solution.5.9 FOAM LIQUID CONCENTRATE A concentrated liquid foaming agent that is intende
22、d to bediluted with water.5.10 FOAM QUALITY EXPANSION RATIO A measure of foams physical characteristics, expressedas the ratio of the final foam volume to original foam solution volume prior to the addition of air.5.11 FOAM SOLUTION A proportioned or premixed homogeneous mixture of water and foam li
