1GENERAL
1.1 Scope
1.1.1 General Requirements, This Standard establishes materials, testing, and marking requirements forsuction fittings that are designed to be totally submergedfor use in swimming pools, wading pools, spas, and hottubs, as well as other aquatic facilities.
1.1.2 Definition. Suction fittings shall be defined asall components,including the sump and/or bodycover/grate,and hardware.
1.1.3 Compliance Demonstration of compliance forthis Standard is merely an indication that the productmeets performance requirements and specifications contained in this Standard.
1.1.4 Revisions. The provisions of this Standardshall not be construed to prevent the use of any alternatematerial or method of construction provided any suchalternate meets the full intent of the standard.
1.1.5 Exclusions
1.1.5,1Skimmers shall be excluded from evaluation to this Standard.
1.1.5.2 Vacuum connection covers shall beexcluded from evaluation to this Standard.
1.1.6 Types of Suction Fittings
1.1.6.1 General. A manufacturer or designer ofany suction outlet cover/grate shall indicate underwhich Type the cover/grate is listed
1.1.6.2 Field Fabricated Outlets. All nonmanufactured suction outlets constructed in the field with individual components shall be considered as “FieldFabricated Outlets.”
11.6.3 Venturi Outlets. All venturi activatedindirect-suction outlets or venturi activated debris collection systems shall be considered as ” Venturi Outlets.”
1.16.4 Swim Jet Combination Fittings. All swimjet combination fittings that combine suction and discharge into one housing, creating a high velocity, highvolume stream of water to swim, jog, or walk againstas well as massage,shall be considered “Swim JetCombination Fittings.”
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.”
1.1.7 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 Drain Use,” “For Single Drain Use,” or “For Multiple Drain 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 fittings 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.
