THE NFPA HANDBOOKS DIFFER FROM CODES AND STANDARDS

Ever wonder what the difference is between an NFPA^® handbook and a code or standard? We’re glad you asked.

NFPA codes and standards both provide requirements for achieving outcomes. Handbooks take a deeper dive, providing the full text of a code or standard as well as expert commentary and features such as graphics, decision trees, testing procedures, case studies, sample forms and checklists, and other helpful aids to give a better understanding of the reasoning behind the requirements and how to apply them.

JUST REMEMBER:

• A code or standard is a framework—a set of rules to follow with a goal to achieve a certain result
• A handbook is a connector—linking requirements to application by helping you understand the reasoning behind a code or standard

The simplest way to think about it is that codes and standards list the technical requirements while handbooks explain those requirements to clarify how to apply them.

Apply NFPA 20, Standard for the Installation of Stationary Pumps for Fire Protection to ensure fire pump readiness and reliability.

NFPA 20 is the industry's trusted source for comprehensive rules concerning stationary fire pump design, electrical and mechanical construction, acceptance testing, and operation. Installers and maintainers rely on this Standard for guidance on the full range of fire pumps -- including centrifugal, vertical shaft turbine-type, and positive displacement -- limited service controllers, and pumps arranged in series. Each successive edition of NFPA 20 builds on new research and experience in the field. Compliance helps users avoid malfunctions and make sure pumps can deliver on cue.

• The 2016 edition of NFPA 20, Standard for the Installation of Stationary Pumps for Fire Protection provides first-time requirements for multistage multiport pumps that give designers and engineers more options. This edition also clarifies the requirements for fire pumps arranged in series with new information designers and contractors will need to know to install these types of pump arrangements correctly and ensure they can communicate as intended.
• The 2013 edition of NFPA 20, Standard for the Installation of Stationary Pumps for Fire Protection responds to industry developments with added coverage of water mist positive displacement pumping units. New provisions addressing diesel engine shutdowns help you avoid equipment damage during testing operations. Other changes include criteria for flow meters to determine accuracy and the need for recalibration. A new rule mandates a flow test within 12 months prior to submission of working plans.
• The 2010 edition of NFPA 20, Standard for the Installation of Stationary Pumps for Fire Protection includes an all-new Chapter 5 on high-rise buildings, with special provisions based on design practices, risk exposure, and fire fighter operations. Some of the most complex fire pump projects are in high-rises, and this edition of the Standard adds information that is vital to engineers, building owners, and AHJs.
• The 2007 edition of NFPA 20, Standard for the Installation of Stationary Pumps for Fire Protection broadens coverage with added information on variable speed drive applications, new calculation methods for pressure relief valves and test header piping, and new applications for pressure reducing valves.
