1、Designation: C1321 09Standard 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 scope islimited to recommendations related to the use and installationof IRCCS, including a surface(s) having a far-infrared emit-tance of 0.25 or less that is sprayed or painted.2Some examplesthat this practice is i
4、ntended to address include: (1) lowemittance surfaces in vented building envelope cavities in-tended to retard radiant transfer across the vented airspace; (2)low emittance surfaces at interior building surfaces intended toretard radiant transfer to or from building inhabitants; and (3)low emittance
5、 surfaces at interior building surfaces intended toreduce radiant transfer to or from heating or cooling systems.See Fig. 1 and Fig. 2 for typical applications.1.2 This practice covers the installation process from pre-installation inspection through post-installation. It does notcover the productio
6、n of the Interior 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 assu
7、mes that the 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 a
8、ffect the installation 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 recommend
9、ed use of the compa-nys products and shall also recommend protective measures tobe employed in their safe utilization. The user shall establishappropriate safety and health practices and determine theapplicability of regulatory requirements prior to use.1.6 This standard does not purport to address
10、all of thesafety 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.

18、iscussionA 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 instrument for
19、 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 installation
20、of an IRCCS will reduce itsthermal effectiveness, cause fire risks and other unsafe condi-tions, and promote deterioration of the structure in which it isinstalled. Specific hazards that can result from improperinstallation include: heat buildup in recessed lighting fixtures,deterioration of failure
21、 of electrical wiring components, anddeterioration of wood structures and paint failure due tomoisture accumulation.4.3 This practice provides recommendations for the instal-lation of IRCCS materials in a safe and effective manner.Actual conditions in existing buildings will vary greatly.4.4 This pr
22、actice presents requirements that are general innature and considered practical. They are not intended asspecific recommendations. Consult the manufacturer for rec-ommended application methods.5. Safety Precautions5.1 The applicator shall wear proper clothing and equipmentas recommended by the manuf
23、acturer and shall follow localcodes and safety regulations for building construction sites.(For example, hard hats, safety goggles, and respiratory pro-tection will be required, depending on site conditions.)5.2 Ventilation shall be provided to insure that mist andoverspray are immediately dispersed
24、 from the application area.If natural ventilation is not adequate, place OSHA approvedfans may be placed in windows or doors adjacent to theapplication area to improve ventilation.5.3 Manufacturers instructions shall be consulted for allapplicable handling and safety recommendations.6. Pre-Installat
25、ion 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, stain, visible fungus growth,rotting, or other structural damage. Do not apply IRCCS insuch areas until t
26、he owner has been informed and has certifiedthese conditions have been corrected and their source(s)eliminated.6.1.2 In areas where the IRCCS is to be applied, compo-nents of the electrical system shall be in good condition. Ifthere is reason to believe the electrical system is faulty, do notapply t
27、he 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 signs of potential electrical deficiencies: lights dimming, fusesblowing, circuit breakers tripping frequently,
28、 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 NFPA 54 and NFPA 211.6.1.3 In areas where an IRCCS is to be applied, theapplicator shall locate and plan the
29、application around venti-lation openings. The applicator shall not apply the IRCCS in away that will plug or otherwise obstruct existing ventilationopenings.6.2 Preparations:6.2.1 All electrical wiring at or near the IRCCS applicationsurfaces shall be protected to ensure that the IRCCS materialcanno
30、t contact the electrical wiring system.6.2.2 Where attic ventilation is compromised by the instal-lation of an IRCCS or the subsequent application of fibrousinsulation, vent baffles shall be installed at the soffits of theattic such that attic ventilation airflows are maintained inaccordance with ap
31、plicable building codes.6.2.3 All materials shall be mixed for at least 2 minimmediately before spraying. Manufacturers instructions shallbe consulted for type of mixing equipment and mixing methodsto be employed. If material is to be sprayed from a pressurepot, the pot shall be equipped with an air

Manufacturers installa-tion instructions and local building codes shall be followed.The manufacturer shall provide product sheet(s) that specif
35、ythe products intended use(s), application method(s), healthand safety considerations, and material properties to include:(1) the IRCCS surface emittance determined in accordancewith Test Method C1371;(2) the applied material water vaportransmission rate, in accordance with Test Methods E96/E96Mand;
36、 (3) the applied material surface burning characteristics inaccordance 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 s
37、urface. After application,foreign materials shall be removed using manufacturers in-structions, 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 deteriorat
