Standard Specification for Fiber-Reinforced Plastic Fans and Blowers
1.1This specification covers centrifugal and axial fans and blowers with airstream components fabricated of fiber-reinforced thermoset plastics (FRP) for corrosion resistance. It is acceptable for internal structures to include encapsulated metal fastening devices, hubs, and shafts.
1.2Reinforcing materials other than fibrous glass are acceptable for use in the fabrication, provided the fans and blowers produced meet all the requirements of this specification.
1.3The term "fans" as used in this specification includes fans and blowers, both centrifugal and axial.
1.4The purpose of this specification is to provide purchasers, system designers, specifiers, and suppliers of FRP fans with minimum standards for fan construction and a common basis for determining safe operating speeds.
1.5The values stated in inch-pound units are to be regarded as the standard. The values given in parentheses are provided for information only.
Note 1:There is no known ISO equivalent to this standard.
Note 2:Appendix X2 contains a list of documents potentially of interest to designers of fan systems.
1.6This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.
1.7This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
