Vapor Corrosion Inhibitors for Use in Fire Sprinkler Systems
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
a) Standard for the Installation of Sprinkler Systems in One- and Two-Family Dwellings and
Manufactured Homes, NFPA 13D;
b) Standard for the Installation of Sprinkler Systems in Low-Rise Residential Occupancies, NFPA
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.
