4.1 In this practice it is recognized that effectiveness, safety, and durability of an RBS depends not only on the quality of the materials, but also on proper installation.4.2 Improper installation of an RBS will reduce the thermal effectiveness, cause fire risks and other unsafe conditions, and promote deterioration of the structure in which it is installed. Improper installations include fires caused by: (1) heat buildup in recessed lighting fixtures, (2) deterioration or failure of electrical wiring components, and (3) deterioration in wood structures and paint failure as a result of moisture accumulation.4.3 This practice provides direction for the installation of RBS products in a safe and effective manner. Actual conditions in existing buildings vary greatly and care shall be taken to ensure safe and effective installation.4.4 In this practice, requirements are presented that are both general and specific in nature and practical. They are not intended as specific instructions unless so indicated. The user shall consult the manufacturer for application and installation methods. The requirements in this practice shall be the minimum material and installation requirements for RBS.1.1 This practice has been prepared for use by the designer, specifier, builder, and the installer of radiant barrier systems (RBS) for use in commercial/industrial building construction not otherwise restricted from use. The scope is limited to instruction relative to the use and installation of RBS, including a surface(s) normally having an emittance of 0.1 or less, such as metallic foil or metallic foil deposits, mounted on substrates. Some examples that this practice is intended to address include: (1) low-emittance surfaces in vented building envelope cavities intended to retard radiant transfer across the airspace: (2) low-emittance surfaces at interior building surfaces intended to retard radiant transfer to, or from, building inhabitants; and (3) low-emittance surface at interior building surfaces intended to reduce radiant transfer to, or from, radiant heating or cooling systems.1.2 This practice covers the installation process from pre-installation inspection through the post-installation procedure. It does not cover the production of the radiant barrier materials. (See Specification C1313.)1.3 This practice is not intended to replace the manufacturer’s installation instructions but shall be used in conjunction with such instructions. This practice is not intended to supercede local, state, federal, or international codes.1.4 This practice assumes that the installer possesses a good working knowledge of the applicable codes and regulations, safety practices, tools, equipment, and methods necessary for installation of radiant barrier materials. It also assumes that the installer understands the fundamentals of commercial/industrial building construction that affect the installation of RBS.1.5 The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard.1.6 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use. For specific precautionary statements see Sections 5 and 7.1.7 When the installation or use of radiant barrier materials, accessories, and systems has the potential to pose safety or health problems, the manufacturer shall provide the user appropriate current information regarding any known problems associated with the use of the product of the company and shall also specify protective measures.1.8 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.

This specification covers single tank, automatic rack type, hot water sanitizing commercial dishwashing machines. Covered by this specification are dishwashing machines of various types (Types I and II based on feed direction, from right or left, respectively), styles (Styles 1-3 based on method of heating: steam, electric, or gas), classes (Classes A-D based on heat source: injector, heat exchange coil, natural gas, or LP gas), sizes, and capacities. Components comprising the dishwashing machine shall be manufactured from corrosion-resistant steel (tank, scrap trays or strainers, overflow drain, access door/s, and legs), corrosion-resisting materials (conveyor, piping and fittings, valves, and spray assemblies), nickel-copper alloys, and plastics. Pump casings shall be of cast iron or corrosion-resisting material. When specified, the dishwashing machine assembly may include a final rinse booster, detergent feeder, and rinse agent feeder. The dishwashing machine shall be tested for performance standards compliance and noise level as well as for operational, leakage, and performance profile requirements. All tests shall comply with the requirements specified.1.1 This specification covers single tank, automatic rack type, commercial dishwashing machines.1.2 The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard.1.3 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.

This specification covers multiple tank, automatic rack less conveyor type, commercial dishwashing machines. These machines can be classified into two types: Type 1 machines shall be designed and supplied to accept the feeding of soiled tableware from the right side, when facing the front of the machine while Type II shall be designed and supplied to accept the feeding of soiled tableware from the left side, when facing the front of the machine. The dishwashing machines have three kinds of styles: Style 1 is a steam heated machine, with two classes namely Class A which uses injectors and Class B which uses heat exchange coils. Style 2 is an electrically heated dishwashing machine. Style 3 on the other hand is gas heated with two classes namely Class C which uses natural gas and Class D which uses LP gas. In addition, these dishwashing machines can be classified into three groups according to size and capacity: Group A, Group B, and Group C. Materials used in the manufacture of these machines shall consist of corrosion-resistant steel, corrosion resisting material, nickel-copper alloy and plastics. The dishwashing machine shall be complete so that when connected to the specified source of power, water supply, heating means (steam, electric, or gas), drainage, detergent, and rinse agent feeder as applicable, the unit can be used for its intended function. Dishwashers shall be rigid, quiet in operation, free from objectionable vibration, and so constructed as to prevent objectionable splashing of water to the outside of the machine. Operational test, leakage test, and performance profiles shall be done in order to determine the overall efficiency of the dishwashing machine.1.1 This specification covers multiple tank, automatic rackless conveyor type, commercial dishwashing machines.1.2 The values stated in inch-pound units are to be regarded as the standard. The SI values given in parentheses are provided for information only.1.3 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
