1、Designation: C1321 14Standard Practice forInstallation and Use of Interior Radiation Control CoatingSystems (IRCCS) in Building Construction1This standard is issued under the fixed designation C1321; the number immediately following the designation indicates the year oforiginal adoption or, in the c
2、ase of revision, the year of last revision. A number in parentheses indicates the year of last reapproval. Asuperscript epsilon () indicates an editorial change since the last revision or reapproval.1. Scope1.1 This practice has been prepared for use by the designer,specifier, and applicator of IRCC
3、S (Interior Radiation ControlCoating Systems) for use in building construction. The scopecontains instructions related to the use and installation ofIRCCS, including a surface(s) having a far-infrared emittanceof 0.25 or less that is sprayed or painted.2Some examples thatthis practice is intended to
4、 address include: (1) low emittancesurfaces in vented building envelope cavities intended to retardradiant transfer across the vented airspace; (2) low emittancesurfaces at interior building surfaces intended to retard radianttransfer to or from building inhabitants; and (3) low emittancesurfaces at
5、 interior building surfaces intended to reduce radianttransfer to or from heating or cooling systems. See Fig. 1 andFig. 2 for typical applications.1.2 This practice covers the installation process from pre-installation inspection through post-installation. It does notcover the production of the Int
6、erior Radiation Control CoatingMaterials.1.3 This practice is not intended to replace the manufactur-ers installation instructions, but it shall be used in conjunctionwith such instructions. This practice is not intended to super-sede local, state, or federal codes.1.4 This practice assumes that the
7、 installer possesses a goodworking knowledge of the application codes and regulations,safety practices, tools, equipment, and methods necessary forthe installation of Interior Coating Materials. It also assumesthat the installer understands the fundamentals of buildingconstruction that affect the in
8、stallation of an IRCCS.1.5 When the installation or use of Interior RadiationControl Coating Materials, accessories, and systems posesafety or health problems, the manufacturer shall provide theuser appropriate current information regarding any knownproblems associated with the intended use of the p
9、roducts andshall also provide direction on protective measures to beemployed for safe utilization. The user shall establish appro-priate safety and health practices and determine the applicabil-ity of regulatory requirements prior to use.1.6 This standard does not purport to address all of thesafety
10、 concerns, if any, associated with its use. It is theresponsibility of the user of this standard to establish appro-priate safety and health practices and determine the applica-bility of regulatory limitations prior to use.

17、pply interiorreflective coating materials in buildings.3.2.2 conditioned spaceany space in a building that isserved by a heating or cooling system.3.2.3 Interior Radiation Control Coating Systems(IRCCS)a building construction consisting of a low emit-tance (0.25 or less) surface bounded by an open a
18、ir space. AnIRCCS is used for the sole purpose of limiting heat transfer byradiation and is not specifically intended to reduce heat transferby convection or conduction.3.2.4 open air spacea vented building cavity (forexample, a vented attic) or a large conditioned or uncondi-tioned building space.3
19、.2.5 DiscussionA large building space is defined as onewhose minimum dimension exceeds two feet.3.2.6 ownerthe person, partnership, corporation, agency,or other entity who owns the building in which the IRCCS isto be applied whether such ownership is by virtue of deed,contract, or any other instrume
20、nt for acquiring legal title underthe laws of the state in which the building is located.4. Significance and Use4.1 This practice recognizes that effectiveness, safety, anddurability of an IRCCS depends not only on the quality of thematerials, but also on the proper installation.4.2 Improper install
21、ation of an IRCCS will reduce itsthermal effectiveness, cause fire risks and other unsafeconditions, and promote deterioration of the structure in whichit is installed. Improper installation has the potential to createspecific hazards that include: heat buildup in recessed lightingfixtures, deterior
22、ation of failure of electrical wiringcomponents, and deterioration of wood structures and paintfailure due to moisture accumulation.4.3 This practice provides directions for the installation ofIRCCS materials in a safe and effective manner. Actualconditions in existing buildings will vary greatly.4.

The user shall consult themanufacturer for application and installation methods.5. Safety Precautions5.1 The applicator shall wear proper clot
24、hing and equipmentas specified by the manufacturer and shall follow local codesand safety regulations for building construction sites. (Ex-amples of safety equipment shall include but are not limited to:hard hats, safety goggles, and respiratory protection and will berequired, depending on site cond
25、itions.)5.2 Ventilation shall be provided to insure that mist andoverspray are immediately dispersed from the application area.When natural ventilation is not adequate, place OSHA ap-proved fans in windows or doors adjacent to the applicationarea to improve ventilation.5.3 The instructions provided
26、by the manufacturer shall beconsulted for all applicable handling and safety requirements.6. Pre-Installation Inspection and Preparation6.1 Inspections:6.1.1 Inspect the roof, walls, ceilings, and floors to identifyareas where previous or existing moisture problems havecaused paint peeling, warpage,
27、 stain, visible fungus growth,rotting, or other structural damage. Do not apply IRCCS insuch areas until the owner has been informed and has certifiedthese conditions have been corrected and the source(s) elimi-nated.6.1.2 In areas where the IRCCS is to be applied, compo-nents of the electrical syst
28、em shall be in good condition. Whenthere is reason to believe the electrical system is faulty, do notapply the IRCCS in such areas until the owner has beeninformed and qualified inspection and repair have been per-formed.NOTE 1The CPSC Product Safety Fact Sheet No. 18 has identified thefollowing sig
29、ns of potential electrical deficiencies: lights dimming, fusesblowing, circuit breakers tripping frequently, electrical sparks and glowingfrom receptacles, light flickering, and cover plates on switches and outletsthat are warm or hot to the touch. Useful safety information is alsocontained in the N

36、e performance of the IRCCS depends on adherenceto the installation instructions provided by the manufacturer.The installation instructions and local building codes shall befollowed. The manufacturer shall provide product sheet(s) thatspecify the products intended use(s), application method(s),health
37、 and safety considerations, and material properties toinclude: (1) the IRCCS surface emittance determined inaccordance with Test Method C1371;(2) the applied materialwater vapor transmission rate, in accordance with Test Meth-ods E96/E96M and; (3) the applied material surface burningcharacteristics
38、in accordance with Test Method E84.7.2.2 The performance of the IRCCS is dependent on themaintenance of an open airspace facing the low emittancesurface.7.2.3 The performance of the IRCCS are affected by foreignmaterials on the low emittance surface. After application,foreign materials shall be remo
39、ved using manufacturersinstructions, taking care not to damage the IRCCS surface.7.2.3.1 Some IRCCS will provide a high resistance to watervapor transmission. An IRCCS shall not be applied so as tolead to moisture accumulation and deterioration in the struc-ture.7.2.4 All roof support structure dire
40、ctly connected to theroof deck (such as purlins, rafters, and top chord of trusses)shall be coated on any exposed surface.7.3 Post-installationThe applicator shall provide a signedand dated statement describing the IRCCS applicator, installedin accordance with Practice C1321 and the area covered.8.
