32、 Private Fire Protection 2018 Edition This edition of NFPA 22, Standard for Water Tanks for Private Fire Protection, was prepared by the Technical Committee on Water Tanks. It was issued by the Standards Council on November 10, 2017, with an effective date of November 30, 2017, and supersedes all pr

33、evious editions. This edition of NFPA 22 was approved as an American National Standard on November 30, 2017. Origin and Development of NFPA 22 In 1909, the NFPA Committee on Gravity Tanks developed the Standard on Gravity Tanks. Amendments were considered in 1912 and 1913, and the standard was adopt

34、ed in 1914. Revised or amended editions were adopted in 1915, 1917, 1918, 1919, 1922, 1926, 1928, 1930, 1931, 1933, 1936, 1941, 1949, and 1950. The name of the committee was changed to the Committee on Water Tanks, and its recommendations resulted in changes adopted in 1957, 1958, 1962, 1965, 1967,

35、1970, 1971, 1974, 1976, 1978, 1981, and 1987. Tanks other than gravity tanks (which, at that time, included concrete reservoirs) and valve pits were rst covered in 1913, pressure tanks (formerly covered by Standards for Sprinkler Systems) were covered in 1915, and tank heating was covered in 1922. T

36、he standard title has been periodically amended to reect the expanded scope of the standard. The 1993 edition provided new, environmentally friendly requirements for tank-coating systems. Two new chapters were included to cover the design and erection of bolted steel tanks and concrete tanks. Inform

37、ation on berglass tanks also was included. These changes, along with other editorial changes, reected the current information for water storage tank design. The 1996 edition of NFPA 22 consolidated tank care and maintenance information within a single chapter. Further revisions addressed the corrosi

38、on resistance of certain tank components, access into tanks, the monitoring of internal conditions, and the structural stresses to which tanks are subjected. The gures in Appendix B were revised to reect current practices. Editorial changes were also made. The 1998 edition further addressed environm

39、ental issues. All inspection, testing, and maintenance requirements were removed and added to the appropriate chapter of the 1998 edition of NFPA 25, Standard for the Inspection, Testing, and Maintenance of Water-Based Fire Protection Systems. The 2003 edition was changed to conform to the Manual of

40、 Style for NFPA Technical Committee Documents, 2000 edition. Referenced publications were updated. The 2008 edition recognized the use of berglass-reinforced plastic (FRP) tanks with a new Chapter 11. Acceptance test requirements were consolidated into a new Chapter 17, “Acceptance Test Requirements

41、,” to improve user-friendliness. The 2013 edition added sizing requirements for break tanks in Chapter 4 and sizing procedures for pressure tanks in the Chapter 7 annex material. The term suction tank was dened, and the requirements for anti-vortex plates were revised. Table 5.4 was updated to align

42、 with current industry standards.WATER TANKS FOR PRIVATE FIRE PROTECTION 22-2 2018 Edition The 2018 edition substantially modied Chapters 5 and 6. In Chapter 5 all duplicate requirements to AWWA D100 have been removed and reference to AWWA D100 has been made; requirements specic to re protection rem

43、ain in Chapter 5. In Chapter 6 all duplicate requirements to AWWA D103 have been removed and reference to AWWA D103 made; requirements specic to re protection remain in Chapter 6. Requirements for check valves in the discharge pipe of a suction tank have been claried in Chapter 14, and tank repair r

44、equirements have been modied requiring the impairment procedures of NFPA 25 to be followed. Chapter 16 has added new criteria for electric immersion heaters, and the lowest one-day mean temperature map has been removed in lieu of using calculations to determine tank heating needs.COMMITTEE PERSONNEL
