  • Description

    Introducing a clearer, more concise, and more effective tool for the installation of sprinkler systems: The 2019 edition of NFPA 13.

    Develop sprinkler defense for any occupancy using the most up-to-date standard -- now completely reorganized based on user needs in the modern built environment. NFPA 13, Standard for the Installation of Sprinkler Systems, has undergone more than 60 revision cycles, reflecting more than 120 years of fire experience and new water-based fire protection technologies. Organizationally, the standard was ready for a change! A task group of water-based fire protection experts tackled the challenge and the 2019 edition of NFPA 13 is the result.

    In a major update, NFPA 13 has been fully reorganized by structuring the technical content in the order you need to do your job.

    NFPA 13 is reorganized from cover to cover, creating clear separations in subject matter and a more logical flow for sprinkler system planning and design. This edition of NFPA 13 makes it easier to locate and apply the latest requirements for automatic sprinkler system design, installation, and acceptance testing; hanging and bracing systems; underground piping; and seismic protection.

    The updated NFPA 13 helps designers, engineers, contractors, and installers work smarter to develop fire sprinkler defense for any occupancy.

    • Content is organized logically by sprinkler technology, storage method, commodity, and how you perform your job.
    • Chapter titles are more descriptive and reflect the terminology in use today.
    • Duplicate content has been removed to help eliminate confusion.
    • A section-to-section number comparison of the 2016 edition to the 2019 edition helps you navigate the reorganized Standard.

    NFPA 13 continues to support your hard work to help prevent fire deaths and property loss.

    Improve your ability to apply requirements for automatic fire sprinklers, for more effective design, installation, maintenance, and code enforcement. The 2019 edition of NFPA 13, Standard for the Installation of Sprinkler Systems, is the transformative next step for anyone involved with water-based fire protection in today's world.

  • How 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.


    • 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 eForms

    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)
