A standard recognizes that effectiveness, safety, and durability of a RBS depends not only on the quality of the materials, but also on their proper installation.Improper installation of a RBS can reduce their thermal effectiveness, cause fire risks and other unsafe conditions, and promote deterioration of the structure in which they are installed. Specific hazards that can result from improper installation 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 due to moisture accumulation.This standard provides recommendations for the installation of radiant barrier materials in a safe and effective manner. Actual conditions in existing buildings may vary greatly and in some cases additional care should be taken to ensure safe and effective installation.This standard presents requirements that are general in nature and considered practical. They are not intended as specific recommendations. The user should consult the manufacturer for recommended application methods.1.1 This standard has been prepared for use by the designer, specifier, and installer of RBS (radiant barrier systems) for use in building construction. The scope is limited to recommendations relative to the use and installation of RBS including a surface(s) normally having a far-infrared emittance of 0.1 or less, such as metallic foil or metallic deposits unmounted or mounted on substrates. Some examples that this standard is intended to address include: (1) low emittance surfaces in vented or unvented 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 surfaces at interior building surfaces intended to reduce radiant transfer to or from radiant heating or cooling systems. See for typical examples of use.1.2 This standard covers the installation process from pre-installation inspection through post-installation procedure. It does not cover the production of the radiant barrier materials. (See Specification C1313.)1.3 This standard 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, or federal codes.1.4 This standard assumes that the installer possesses a good working knowledge of the application codes and regulations, safety practices, tools, equipment, and methods necessary for the installation of radiant barrier materials. It also assumes that the installer understands the fundamentals of building construction that affect the installation of RBS.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 and health practices and determine the applicability of regulatory limitations prior to use. For specific precautionary statements, see Sections and .1.5 When the installation or use of radiant barrier materials, accessories and systems, may pose safety or health problems, the manufacturer shall provide the user appropriate current information regarding any known problems associated with the recommended use of the company's products and shall also recommend protective measures to be employed in their safe utilization. The user shall establish appropriate safety and health practices and determine the applicability of regulatory requirements prior to use.

4.1 This practice is for use by designers and specifiers, regulatory agencies, owners, and inspection organizations involved in the rehabilitation of non-pressure sewers and conduits. As for any practice, modifications may be required for specific job conditions.1.1 This practice describes the procedures for the rehabilitation of sewer lines and conduits by the installation of a field-fabricated PVC liner. After installation of the liner, cementitious grout is injected into the annular space between the liner and the existing sewer or conduit. The rehabilitation of the host structure by this installation practice results in a rigid composite structure (PVC/grout/existing pipe). This rehabilitation process may be used in a variety of gravity applications, such as sanitary sewers, storm sewers and process piping of man-entry sizes (36 to 144 in. in vertical dimension). The profile strips used for field fabrication of PVC liners are supplied in coils for spiral winding of the liner or in custom-cut flat panels for circumferential lining of all or any portion of the circumference of the host conduit (see Figs. 1 and 2).FIG. 1 Example of Profile PVC StripFIG. 2 Typical Installations with Panels1.2 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 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. Particular attention is drawn to those safety regulations and requirements involving entering into and working in confined spaces.1.4 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.

1.1 This guide describes the specification and re-construction of in-situ pipelines and conduits 2 in. to 63 in. (50 mm to 1600 mm) diameter) by the pulled-in-place installation, into an existing conduit, of circular, radially reduced, Shape-Memory-Polymer Tubular (SMPT) that after installation, re-expands (by “memory”) to press against the ID of the host pipe, thus coupling the interior pipe, by friction fit, as reinforcement to the host pipe. The added SMPT pipe wall restores leak tightness and adds its strength to the host pipe (Dual-Wall Composite-Pipe). It becomes a continuous compressed-fit dual-wall pipeline. Depending upon the SMPT compound used, the re-constructed pipelines or conduits are suitable for pressure and nonpressure pipeline applications such as process piping, raw and treated water transmission, water pipe systems, forced-mains, industrial and oil-patch gathering and transmission pipelines, sanitary sewers, storm sewers, and culverts.NOTE 1: This standard guide covers circular SMPT tubulars which are radially reduced by mechanical means at the time of installation. This guide does not address “liners” that at the time of manufacture are deformed (folded) into U-shape, C-shape, H-shape, or other such configurations. This guide refers to dual-wall meaning two layers of pipe co-joined in the field, which is different from dual-wall factory-made co-extruded pipe or corrugated pipe. This guide does not provide a complete design basis covering the many variables required for design and construction of this field fabricated product; the advice of professional contractors and/or registered professional engineers may be incorporated as an adjunct to this guide.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.NOTE 2: There are no ISO standards covering the primary subject matter of this guide.1.3 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.1.4 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.
