2019 Edition

Revised to recognize new technologies and improve application, the 2019 edition of NFPA 20 helps you provide state-of-the-art fire protection.

Industry-trusted NFPA 20, Standard for the Installation of Stationary Pumps for Fire Protection gives you the latest provisions to help ensure fire pump readiness and reliability. This Standard offers comprehensive requirements for fire pumps, limited service controllers, and pumps in series. Designers, engineers, contractors, and installers can look to this expanded source for the latest coverage of today's technologies and up-to-date requirements for:

• Fire pump design
• Electrical and mechanical construction
• Acceptance testing
• Operation

Added requirements address recent advancement in the field.

This edition includes first-time or expanded coverage of technologies such as:

• Automated inspection and testing
• Distance monitoring
• Automated valves
• Self-regulating variable speed fire pump units

Other improvements help you avoid errors and misinterpretations.

The requirements for hydraulic cranking systems are revised to distinguish between systems used as primary cranking systems and those used as secondary cranking systems. Annex C is revised significantly to make data formatting more universal. New definitions include the term very tall building, and the requirements pertaining to this type of building are expanded, including those for automatic tank refill valves. For the facts you need on fire pumps, update to the new NFPA 20. (Print,198 pp., 2019)

Other Editions

• 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.

If you purchased a PDF, licensed PDFs can be accessed immediately. Instructions can be found in your order confirmation.

Effective with the annual 2020 code cycle, NFPA^® will no longer offer access to the PDF format as a choice for new editions of codes and standards, handbooks, or other reference titles. Existing PDFs will remain in-market and will still be accessible in our National Fire Codes^® Subscription Service (NFCSS™).

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.

NFPA^® makes available PDF versions of some forms originally published in earlier editions of our NFPA Standards and handbooks. These eForms allow you to fill in the form fields electronically and then save, print, or share the file. NFPA eForms are intended for use on computers and are compatible with some mobile devices and apps. An internet connection is not needed to fill in and save the forms once they are downloaded to your device.

NFPA eForms can be used with many PDF applications. Functions of the specific PDF application will work on the forms. For example, most PDF applications include a signature feature, allowing you to use your finger, stylus, or mouse to sign a document. Note that it is recommended that the eForms be viewed and filled in through Adobe Acrobat Reader or higher, and not using the default reader of your device, for example, the iOS reader on iPhones.

Note that NFPA eForms are not compatible with the NFPA eLibrary app.

Features of the NFPA eForms include:

• Editable fields and checkboxes that allow you to enter content
• Spell check
• Easy file sharing (through email or Cloud storage)
• Printing
• Basic PDF markup tools, including highlighting and comment boxes
• A "Learn More" button with explanatory comments to help you understand the requirements necessary to complete the form
