3.2.5 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. 3.3 General Definitions. 3.3.1 Braided Reinforcement.

[1961, 2013] In no event shall the relief valve be set to relieve at a pressure that exceeds 90 percent of the service test pressure of the hose used with the system. 4.1.11 Damage Prevention.* Hose, while in use, shall be positioned to minimize mechanical damage and heat exposure.* Vehicles shall not be driven over charged or uncharged fire hose unless the hose is bridged and the vehicle has sufficient ground clearance to cross the bridged hose.* Nozzles and valves shall be opened and closed slowly to prevent pressure surges and water hammer that can burst the hose and in turn cause injury to people or damage to the pump. Care shall be taken to prevent the hose from chafing. Care shall be taken to avoid dragging large- diameter fire hose, but if the hose must be dragged, it shall be dragged when flat.* When hose is in use during subfreezing weather, care shall be taken to prevent water from freezing inside the hose.NFPA 1962 pdf download.
