13、irements cover special purpose nonmetallic containers and tanks (vessels) for specificaboveground use applications for combustible or non-combustible liquids as indicated for each specialpurpose type, which are intends to address the specific designs, features, limitations, use factors andother uniq
14、ue characteristics of each type. The basic types of different special purpose vessels covered bythis Outline are:a) Liquid Chemical Containers and Tanks designed for stationary storage of combustible ornon-combustible liquids in non-residential applications, and are intended to be used inaccordance
15、with NFPA 30, Chapter 9 (Storage of Liquids in Containers GeneralRequirements), Section 9.4 (Acceptable Containers and Tanks). Liquid chemical tanks arelimited to the specific liquid(s) or family of similar liquids and application(s) to which they arerated under the evaluation; andb) Cooking Oil Tan
16、ks designed for storage of cooking oils and fats typically found in restaurantor similar commercial food preparing applications having engineered transfer systems. Thesetanks are intended for either delivery of fresh oil and/or collection of waste oils by trainedpersons using service trucks with pre
17、ssure or vacuum pumps through piping networks. Thesetanks are limited to Class IIIB oils b) Consumer Portable Fuel Cans in accordance with ASTM Standard Specifications forGasoline (ASTM F852) or Diesel c) Portable Containers and Tanks in accordance with UL 75;d) Commercial Safety Cans in accordance
18、with UL 1313; ore) Oil Burner Tanks in accordance with UL 2258.1.3 All special purpose vessels are factory manufactured atmospheric types of primary, secondary ordiked containment designs, and may be constructed in any shape, size or capacity as allowed for eachvessel type. The containment materials
19、 are formed from primarily thermoplastic or thermoset polymerswith or without integrated metallic components.OCTOBER 2, 2015 UL 2152 5UL COPYRIGHTED MATERIAL NOT AUTHORIZED FOR FURTHER REPRODUCTION ORDISTRIBUTION WITHOUT PERMISSION FROM UL1.4 In addition to basic requirements for the vessels structu
20、ral integrity, material compatibility,environmental exposures and fire resistance, optional requirements for accessories covered in this outlinethat are installed in/on the tank, such as supports, pumps, heaters, gauges, filters, hoses, valves, controlsmay be included in the evaluation.1.5 Any acces
21、sories or components not evaluated under 1.4 that are shipped with, attached to, or addedto the tanks are not included in the scope of the vessels evaluation. It is intended that the AHJ approvethe use and/or installation of any such accessories or components independent of the evaluated tank.1.6 Th
22、ese requirements do not cover special evaluations for resistance to hurricanes, tornadoes,earthquakes, floods, or other natural disasters; or large scale fire and excessive damage resistance. Inaddition, assessment of any damage for continued use after such events, are not included in theevaluation.
