NFPA75 Standard for the Protection of Information Technology Equipment 2009 Edition This edition of NFPA 75, Standard for the Protection of Information Technology Equipment, was prepared by the Technical Committee on Electronic Computer Sys
23、tems and acted on by NFPA at its June Association Technical Meeting held June 25, 2008, in Las Vegas, NV. It was issued by the Standards Council on July 24, 2008, with an effective date of September 5, 2008, and supersedes all previous editions. This edition of NFPA75 was approved as anAmerican Nati
24、onal Standard on September 5, 2008. Origin and Development of NFPA 75 The Committee on Electronic Computer Systems was formed by the action of the NFPA Board of Directors in January 1960, following a request for standardization of fire protection recommendations by the computer industry. The committ
25、ee first submitted the Standard for the Protection of Electronic Computer Systems to the 1961 NFPAAnnual Meeting, and it was tentatively adopted.At the 1962Annual Meeting, it was officially adopted as an NFPAstandard. Revisions were adopted in 1963, 1964, 1968, 1972, 1976, 1981, 1987, and 1989. The
26、document was completely rewritten for the 1992 edition. The document was revised in 1995, 1999, and again in 2003. The 2003 edition incorporated the Manual of Style for NFPATechnical Committee Documents revisions. In editions of this standard prior to 2003, the terms “electronic computer/data proces
27、sing equipment” and “electronic computer system” were used where the current terms “informa- tion technology equipment” and “information technology equipment system,” respectively, are used. Similarly, the terms “computer room” and “computer area” were replaced by “infor- mation technology equipment
28、 room” and “information technology equipment area,” respec- tively. While the title and some terminology were changed in the 2003 edition to more closely align this standards terminology with terminology being used in other standards, such as NFPA 70, National Electrical Code, and UL 60950, Safety o
29、f Information Technology Equipment, the scope of this standard and any definitions associated with thoselike terms remained the same. For the 2009 edition, Section 4.2, Telecommunications Risks, has been updated; many of the UL references have been updated; new requirements have been added for signa
30、ge to indicate that equipment will remain energized where continuous power is provided; and flame spread indexes have been provided for many of the materials listed in the standard. 751 NFPA and National Fire Protection Association are registered trademarks of the National Fire Protection Associatio
