NFPA 1122-2018 PDF Download

NFPA 1122-2018 is a standard that aims to promote the safe practice of model rocketry. This standard applies to the design, construction, and use of model rocket motors and reloading kits for recreational, educational, and sporting purposes.

One notable change in the 2017 edition of NFPA 1122 is the inclusion of a provision that allows rocketry users to calculate minimum launch site dimensions using readily available software. This change provides an alternative method for determining launch site dimensions, especially for customized rocket designs or kits that may not have manufacturer-provided specifications. Users can calculate the estimated flight altitude of their rockets based on motor specifications, which then informs the minimum launch site dimensions required for safety.

Additionally, the 2017 edition includes an update to the National Association of Rocketry's Model Rocket Safety Code in Annex B, aligning it with the current 2012 edition. This ensures that the standard reflects the latest industry best practices and safety guidelines.
