UL Standards & Engagement Vapor Corrosion Inhibitors for Use in Fire Sprinkler Systems UL 2901B

1.1 This Standard covers requirements for vapor corrosion inhibitors and their delivery system for use in fire sprinkler systems.

1.2 These corrosion inhibitors are intended for use in dry pipe and pre-action sprinkler systems for installation in accordance with the manufacturer's design and installation instructions and the following standards:

1. a) Standard for the Installation of Sprinkler Systems in One- and Two-Family Dwellings and Manufactured Homes, NFPA 13D;
2. b) Standard for the Installation of Sprinkler Systems in Low-Rise Residential Occupancies, NFPA 13R; and
3. c) Standard for Installation of Automatic Sprinkler Systems, NFPA 13.

1.3 These corrosion inhibitors are intended for use in dry pipe and pre-action sprinkler systems and intended to be inspected, tested and maintained in accordance with the Standard for Inspection, Testing and Maintenance of Water Based Fire Protection Systems, NFPA 25.

1.4 This Standard does not contain requirements for delivery systems that use electricity.

1.5 The requirements of this Standard evaluate the safety and compatibility of vapor corrosion inhibitors when used in a fire sprinkler system but do not evaluate the level of corrosion protection provided by an individual vapor corrosion inhibitor.
