NFPA 4 – Standard for Integrated Fire Protection and Life Safety System Testing
۲۰۲۱ Edition
This edition of NFPA 4, Standard for Integrated Fire Protection and Life Safety System Testing, was prepared by the Technical Committee on Commissioning and Integrated Testing and acted on by the NFPA membership during the 2020 NFPA Technical Meeting held June 8-29. It was issued by the Standards Council on August 11, 2020, with an effective date of August 31, 2020, and supersedes all previous editions.
This edition of NFPA 4 was approved as an American National Standard on August 31, 2020.
Origin and Development of NFPA 4
The basis for NFPA 4, Standard for Integrated Fire Protection and Life Safety System Testing, was Chapter 7 of the 2012 edition of NFPA 3, Recommended Practice for Commissioning of Fire Protection and Life Safety Systems. This chapte1· addressed integrated system testing as part of the overall fire protection and life safety system commissioning concept. Both the 2012 and 2015 editions ofNFPA 3 we1·e released as recommended practices as opposed to standards, which meant that the concept of integrated system testing was not required, but was only described as a best practice.
The Technical Committee on Commissioning and Integrated Testing detennined that while commissioning fire protection systems was not ready for standardization, there was an imminent need to create a standard for testing integ1·ated fire protection and life safety systems. The technical committee requested to separate the concepts of commissioning and integrated system testing into two documents: the first, a recommended practice on commissioning; and the second, a new standard, NFPA 4, addressing the integrated system testing portion. This restructuring and request for a new project was approved by the Standards Council in October 2011 and resulted in Chapter 7 of the 2012 edition of NFPA 3 being removed for the 2015 edition and being used as the basis for NFPA4.
NFPA 4 is intended to address d1e testing of d1e performance of the interconnection between multiple fire protection and life safety systems. Chapter 1 establishes the applicability of the standard and identifies d1at the standard is applied similar to a design or installation standard, from the perspective that the users should be directed to d1is standard by scoping provisions in a code, law, regulation, or contract document.
NFPA 4 addresses the development of d1e integrated testing team and the coordination between the integrated testing agent5 (ITa) and test team. The standard spells out the roles and responsibilities of the owner, the ITa, and the test team in general, as well as qualifications for the ITa.
This standard also provides protocols for both the initial integrated system test that would occur during the construction phase of a project prior to issuance of the Certificate of Occupancy, as well as the integrated system testing for existing buildings. Integrated system testing in existing buildings can be in the form of periodic integrated system testing or trigger-based testing. NFPA 4 provides the ·iggers for conducting d1ese post-occupancy integrated system tests, as well as the development of a frequency of periodic tests where they are deemed necessary.
Finally, the standard addresses the development of the test plan and d1e test scenarios, as well as the documentation of the test.
Chapter 1 was reorganized to eliminate redudancy, place paragraphs in the appropriate section, and comply with the NFPA Manual of Style. Many of the other changes were made to bring the standard into compliance with the NFPA Manual of Style.
