ASME A112.18.9:2011 pdf free download Protectors/ Insulators for Exposed Waste and Supplies on Accessible Fixtures
1GENERAL1.1 Scope
This Standard shall show material and performancespecifications and use of protectors / insulators forexposed waste and supplies for public / commercial andprivate / residential buildings using product coveredunder this Standard.
This Standard is intended to also cover products thatwill satisfy the requirements of ICC/ ANSI A117.1,Standard for Accessible and Usable Buildings andFacilities for Persons With Physical Disabilities, and toestablish a generally acceptable performance standardfor protectors / insulators for exposed waste and sup-plies, so a physically challenged person will be protectedwhen using a sink or lavatory in a public / commercialor private / residential facility.
1.2 Units of Measurements
Values are generally stated in U.S.Customary unitsand International System of Units (SI). U.S. Customaryunits shall be considered as the standard.
DEFINITIONS
accessible fixture: a plumbing fixture that complies withthe requirements of ICC/ANSI A117.1,Standard forAccessible and Usable Buildings and Facilities forPersons With Physical Disabilities.
protectors/insulators: individual covers over waste andsupply pipes that isolate them to prevent injury fromcontact with hot, cold, or sharp surfaces.
supplies: the exposed water pipes to a fixture fitting con-sisting of stop valves and riser tubing under a sink orlavatory.
voids: any unprotected area of exposed waste and sup-plies that could contact the user.
zwaste: standard drains with tailpieces and P-traps, stan-dard drains with tailpieces and bottle traps, or offsetdrains using 90-deg elbows, horizontal legs, vertical tail-pieces, and P-traps.

DESIGN REQUIREMENTS4.1 General Requirements
Trap protectors / insulators shall be designed to fit thespecified size of the trap.A single size trap protector /insulator shall be permitted to accommodate multiplesizes of traps: 11/4 in., as well as 1/ in. or 2 in. nominal.Field-applied protectors / insulators shall have enoughfasteners to securely fasten the protectors / insulatorsover the drain pipe assemblies, water supply risers,andstops.A fastener consisting of a single, continuous seamshall also be acceptable. Fasteners shall not present sharpor abrasive external surfaces. Devices covered by thisStandard shall be removable, reusable,and after reas-sembly meet the requirements of this Standard.
4.2 Heat Transfer
Protectors / insulators for exposed waste and suppliesshall be engineered to comply with the heat transferrequirements contained in para.5.1.
4.3 Workmanship
Exterior surfaces of protectors / insulators for exposedwaste and supplies exterior surface shall be smooth andwater resistant, having no sharp or abrasive features orprotrusions.
4.4 Water Resistance
Protectors / insulators for exposed waste and suppliesshall meet the water resistance requirements containedin para.5.3.
4.5 Fungus Growth Resistance
Protectors / insulators for exposed water supply anddrainpipes shall conform to the fungus growth resist-ance requirements of para.5.4.
5PERFORMANCE REQUIREMENTS AND TEST
METHODS
5.1 Heat Transfer Test
Tests shall be conducted at a room temperature of73.4°F ± 3.6F(23°C ± 2C).One sample of eachprotector / insulator shall be installed on the recom-mended supply or waste assembly in accordance withthe manufacturers” instructions. Maintain the waterflowing through the supplies or waste at a water temper-ature at 140°F ± 2°F (60C± 1.18C) for a period of 5 hr.A thermocouple attached to the outside wall of the pro-tector / insulator shall be used to record the temperatureevery 15 min over the length of the test.
NOTES:
(1) If the manufacturer’s specification covers more than one size
of fitting for the protector / insulators. the larger size of thefitting shall be used for testing.
(2) The temperature-measuring devices or thermocouples shall be
placed on the hottest spots of the outside wall of the protector /insulators.[Exception: Thermocouples shall be placed a mini-mum of 2 in.(50.8 mm) from the wall for supply stops.]
5.1.1 Performance Requirements.Surface tempera-ture of the protector / insulator shall not rise above95°F(35°C).
5.2 Surface Deflection and Load Test
Using a 1/ in.(12.7 mm) diameter metal rod, apply a10 lb (44.5 N) force at a right angle against the outsidewall of P-trap, supply stops, or riser protector for 10 sec.
5.2.1 Performance Requirements.The surface shallnot crack or show signs of voids. After the load isremoved for 5 min, the outside surface shall have noindentation where the load was applied.
