3 Chapter 2 Referenced Publications Section 2.3 Other Publications NFPA 70 (NEC) References 2014 edition NFPA 72 (Fire Alarm & Signaling) References 2013 edition ASME Boiler and Pressure Vessel Code References 2013 edition ASME B31.1 Power Piping Code References 2012 edition ANSI/UL 2127 (Inert Gas) & 2166 (Halocarbon Gas) 2012 Edition, UL aligned to ANSI to ease international efforts
4 Chapter 3 Definitions Section 3.2 NFPA Official Definitions 3.2.6 Standard An NFPA Standard, the main text of which contains only mandatory provisions using the word shall to indicate requirements and that is in a form generally suitable for mandatory reference by another standard or code or for adoption into law. Nonmandatory provisions are not to be considered a part of the requirements of a standard and shall be located in an appendix, annex, footnote, informational note, or other means as permitted in the NFPA Manuals of Style. When used in a generic sense, such as in the phrase standards development process or standards development activities, the term standards includes all NFPA Standards, including Codes, Standards, Recommended Practices, and Guides.
5 Section 3.3 General Definitions Two definitions have been added: 3.3.28 Recovered Agent Agent that has been removed from a system and kept for future use or until it is destroyed, without necessarily testing or processing it in any way. 3.3.29 Recycle Agent Agent that has been recovered, tested, and processed as necessary and found to be in compliance with the quality requirement of 4.1.2.
6 Chapter 4 Components Section 4.1.4 Agent Storage Containers 4.1.4.4 Means to determine pressure in containers changed from refillable superpressurized containers to containers of inert gas agents, superpressurized liquid agents, and superpressurized liquefied compressed gas agents. More specific to pressurized containers 4.1.4.6 Took out wording on external heating or cooling of containers.
7 Chapter 4 Components Section 4.2 Distribution 4.2.1 Pipe Updated reference requirements of B31.1 4.2.1.1(3) Added specifies inert gas piping shall use 4.2.1.1.1 and 4.2.1.1.2 4.2.1.1.1 Updated to better reflect the common use of pressure reducers in inert gas piping. Highlighted section below added/updated:
Chapter 4 Components Section 4.2 Distribution continued Table 4.2.1.1(a) New storage pressure added to Nitrogen (IG-01) and updated, reduced pressures for Inergen (IG-55). See Highlighted data below. 8 Added 4.2.1.1.2 Further guidance on pressure reducing device: design pressure for piping based on flow calculation after the pressure reducing device.
Chapter 4 Components Section 4.2 Distribution continued Added 4.2.1.1.3 Piping for pre-engineered systems shall be designed in accordance with the manufacturers listed manual. 4.2.3.2 & 4.2.3.3, Simplifies and highlights that there is to be NO USE OF FITTINGS NOT RATED FOR PROPER PRESSURES! Added 4.2.4.2 Flanged valves require proper class of flange to connect. 9
Chapter 4 Components Section 4.2 Distribution continued Added 4.2.5.5 provides guidance on distances from obstructions required to nozzle location. Also added annex material on this subject. Added 4.3.3.5.3 automatic type systems in non occupied spaces do not require manual release. This covers bulb and Direct type systems. 10
11 Chapter 5 System Design Added 5.4.2.1.1 Which requires calibration of cup burner method equipment and helps to keep the agent manufacturers testing consistent. 5.5 Total Flooding Quantity 5.5.1.1 Added equation for minimum and maximum temperature concentration calculation per standard requirements 5.5.1.2 Reference to Total Flooding quantities tables in Annex moved to 5.5.2.2, this information is still available in the annex. Replaced with 5.5.1.2, new 5.5.1.2 now requires that the halocarbon agent concentration calculated at the highest and lowest temps shall be included on the system as-built drawings and flow calculations 5.5.2 Equation updated for ease of use
12 Chapter 5 System Design Continued 5.5.1.2 now requires that agent concentration calculated at the highest and lowest temps shall be included on the system as-built drawings and flow calculations 5.6 Duration of protection 85% of adjusted minimum design shall be held at the highest level of combustibles has been changed to highest height of protected content 5.7.1.1 removed elaborated on what rate of application is, unnecessary
13 Chapter 6 Local Application Systems 6.4.3.1 Local App Discharge Time added wording on mechanical rundown time for extended discharges 6.5.3 Local App Linear Detection Tubing Direct type system now allowed.
Chapter 7 Inspection, Testing, Maintenance, and Training 7.1.2 Inspection reports can be filed using electronic media (ie Building Reports) Added new 7.1.6 Clarifies that recovered Clean Agents shall not be released into the atmosphere Old 7.1.6 became 7.1.7 (Inspection Tag) Added 7.7.2.1 & 7.7.2.2 Stating that installation acceptance testing shall be documented in a test report and maintained by the owner for the life of the system 7.7.2.4.12 through 7.7.2.4.12.2 Clarifies the pipe pressurization checkout method wording 14
15 Appendix 7.7.2.1 Test Report
16 Changes to Appendix A.1.6 GWP & ODP Defined
17 Changes to Appendix New Section Added A.5.5.3 Considerations and Conditions Requiring Increased Design Factors Unclosable Openings Acid Gas Formation Considerations Fuel Geometry Considerations Enclosure Geometry Obstructions Within the Enclosure
18 Changes to Appendix FSSA (Fire Suppression Systems Association) now referenced for multiple publications to assist designers. A.4.3.1.1 Detection & Control Guide A.5.1.2.2(28) Pressure Relief Estimating Document A.7.1.2 Design Guide A.7.2 Container Guide
19 Summary of Primary Changes Requirement of notification on electrical actuator removal Recovered/Recycled Agents now defined; recycled agents permitted Agent calculation requirement for low and high temperature of protected space No manual release required for automatic systems when unoccupiable & personnel not normally present Detection tubing permitted for use as nozzle in local app Annex Changes Environmental definitions FSSA references added Addition of acceptance test report Design factor considerations
