1 GENERAL 1.1 Scope 1.1.1 General Requirements. This Standard estab- lishes materials, testing, and marking requirements for suctionfittings thatare designedto betotallysubmerged for use in swimming pools, wading pools, spas, and hot tubs, as well as other aquatic facilities. 1.1.2 Definition. Suction fittings shall be defined as all components, including the sump and/or body, cover/grate, and hardware. 1.1.3 Compliance. Demonstration ofcompliance for this Standard is merely an indication that the product meets performance requirements and specifications con- tained in this Standard. 1.1.4 Revisions. The provisions of this Standard shall not be construed to prevent the use ofany alternate material or method of construction provided any such alternate meets the full intent of the standard. 1.1.5 Exclusions 1.1.5.1 Skimmers shall be excluded from evalua- tion to this Standard. 1.1.5.2 Vacuum connection covers shall be excluded from evaluation to this Standard. 1.1.6 Types of Suction Fittings 1.1.6.1 General. A manufacturer or designer of any suction outlet cover/grate shall indicate under which Type the cover/grate is listed. 1.1.6.2 Field Fabricated Outlets. All nonmanufac- tured suction outlets constructed in the field with indi- vidual components shall be considered as “Field Fabricated Outlets.” 1.1.6.3 Venturi Outlets. All venturi activated indirect-suction outlets or venturi activated debris col- lection systems shall be considered as “Venturi Outlets.” 1.1.6.4 Swim Jet Combination Fittings. All swim jet combination fittings that combine suction and dis- charge into one housing, creating a high velocity, high volume stream of water to swim, jog, or walk against, as well as massage, shall be considered “Swim Jet Combination Fittings.” 1 1.1.6.5 Submerged Suction Outlets. All other suc- tion outlets for use in swimming pools, wading pools, spas, and hot tubs, as well as all other aquatic facilities, shall be considered as “Submerged Suction Outlets.” 1.1.6.6 Self-Contained Spa Fittings. Suction outlet fittings used exclusively in self-contained factory manu- factured spas shall be considered “Self-Contained Spa Fittings.” 1.1.7 Single or Multiple Usage 1.1.7.1 Cover/grates that pass the body entrap- ment portion of this Standard as well as meeting all other requirements in this Standard shall be perma- nently marked “For Single or Multiple Outlet Use,” “For Single Outlet Use,” or “For Multiple Outlet Use Only” at the manufacturer’s option. 1.1.7.2 Cover/grates that fail the body entrap- ment portion of this Standard or any other requirements of this Standard may not be certified under this Standard. 1.2 Related Standards Since the scope of this Standard is directly related to suction fittings, it is important to mention that the fit- tings themselves represent only one portion of the suc- tion entrapment scenario. Several other standards, including but not limited to, ANSI/NSPI-1, -2, -3, -4, -5, -6, and -8, ANSI/IAF-9, as well as ASME A112.19.17, and ASTM F 2387-04, as outlined in para. 1.4, should be consulted so as to provide coverage for the various other aspects of this potential hazard in swimming pools, wading pools, spas, and hot tubs. 1.3 Units of Measurement When values are stated in U.S. Customary units and in the International System of Units (SI), the values stated in U.S. Customary units shall be considered as the standard. 1.4 References The following standards are referenced in this docu- ment. Unless otherwise specified, the latest edition shall apply. ANSI/IAF-9, Aquatic Recreation Facilities ANSI/NSPI-1, Standard for Public Swimming Pools
complete system: comprising a pump, suction outlet (and possibly inlet), and connecting piping as specified by manufacturer. No other operating components or valves may be included. Safety devices, vents, suction vacuum release systems, etc., shall be used only as specified by the manufacturer. Nonoperating components such as drains are permitted. cover: a fitting or device generally placed between the suctionpipingand the bather. Notused inthis document to avoid confusion. See also cover/grate. cover/grate: covering fitting or assembly that separates the bather from the suction sump or piping, sometimes referred to as a “grate” or a “cover.”
