This specification covers requirements, test methods, and methods of marking for chlorinated poly(vinyl chloride) plastic hot- and cold-water distribution system components made in one standard dimension ratio and intended for water service up to a certain temperature. These components comprise pipe and tubing, socket-type fittings, street fittings, plastic-to-metal transition fittings, solvent cements, and adhesives. The components are intended for use in residential and commercial, hot and cold, potable water distribution systems. The products covered by this specification are intended for use with the distribution of pressurized liquids only, which are chemically compatible with the piping materials. CPVC 4120 pipe, tubing, and fittings shall be classified by a single standard dimension ratio which shall be SDR 11, by a certain maximum continuous use temperature and by a certain diameter range for nominal pipe or tubing. CPVC plastic-to-metal transition fittings intended for use up a certain temperature are classified on the basis of resistance to failure by thermocycling. The chlorinated poly(vinyl chloride) plastics are categorized by two criteria: basic short-term properties and long-term hydrostatic strength. These short-term properties include mechanical strength, heat resistance, flammability, and chemical resistance which shall be determined after performing different tests. A test shall also be conducted in order to determine the long-term hydrostatic strength of CPVC 41 pipe, tubing, and fittings.1.1 This specification covers requirements, test methods, assembly, and methods of marking for chlorinated poly(vinyl chloride) plastic hot- and cold-water distribution system components made in one standard dimension ratio and intended for water service up to and including 180 °F (82 °C). These components comprise pipe and tubing, socket-type fittings, street fittings, plastic-to-metal transition fittings, solvent cements, and adhesives. Requirements and methods of test are included for materials, workmanship, dimensions and tolerances, hydrostatic sustained pressure strength, and thermocycling resistance. The components covered by this specification are intended for use in residential and commercial, hot and cold, potable water distribution systems.1.2 The products covered by this specification are intended for use with the distribution of pressurized liquids only, which are chemically compatible with the piping materials. Due to inherent hazards associated with testing components and systems with compressed air or other compressed gases some manufacturers do not allow pneumatic testing of their products. Consult with specific product/component manufacturers for their specific testing procedures prior to pneumatic testing.NOTE 1: Pressurized (compressed) air or other compressed gases contain large amounts of stored energy which present serious safety hazards should a system fail for any reason.1.3 The text of this specification references notes, footnotes, and appendixes which provide explanatory material. These notes and footnotes (excluding those in tables and figures) shall not be considered as requirements of the specification.1.4 The values stated in either SI units or inch-pound units are to be regarded separately as standard. The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. Combining values from the two systems may result in non-conformance with the standard.NOTE 2: Suggested hydrostatic design stresses and hydrostatic pressure ratings for pipe, tubing, and fittings are listed in Appendix X1. Design and installation considerations are discussed in Appendix X2. An optional performance qualification and an in-plant quality control program are recommended in Appendix X3.1.5 The following safety hazards caveat pertains only to the test method portion, Sections 9 and 10, of this specification: 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.1.6 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 the properties and requirements for electrical insulating tape consisting of a backing of vinyl chloride plastic, coated on one side with a pressure-sensitive adhesive, for use at low temperatures. Four types are included providing two thicknesses at two operating temperatures. Selected from standard widths and lengths, the tapes shall conform to specified values of the following requirements: break strength; break and static elongation; dielectric breakdown; adhesion to both steel and backing; roll unwind; high-humidity insulation resistance; flammability; and behavior during flagging test.1.1 This specification covers an electrical insulating tape for use at low temperature down to approximately -18°C (0°F). The tape consists of a backing of vinyl chloride plastic, coated on one side with a pressure-sensitive adhesive. Four types are included providing two thicknesses at two operating temperatures.1.2 The values stated in SI units are the standard. The values given in parentheses are provided for information purposes only.

This specification establishes requirements for the material properties, including dimensional stability, weatherability, and extrusion quality, of rigid poly(vinyl chloride) (PVC) exterior profile extrusions used for assembled windows and doors. Methods for testing and for identifying exterior profile extrusions that comply with this specification are also provided. The physical and performance requirements of PVC are presented in details. The dimensional stability and impact strength shall be tested to meet the requirements prescribed.1.1 This specification establishes requirements for the material properties, including dimensional stability, weatherability, and extrusion quality, of rigid poly(vinyl chloride) (PVC) exterior profile extrusions used for assembled windows and doors. Methods for testing and for identifying exterior profile extrusions that comply with this specification are also provided.1.2 The use of rigid PVC recycled plastic in this product shall be in accordance with the requirements in Section 6.NOTE 1: Information with regard to application, assembly, and installation should be obtained from the manufacturers of the profiles and of the windows and doors.NOTE 2: Refer to Specification D3678 for interior profile extrusions.1.3 Color-hold guidelines are provided in an appendix for the manufacturer’s product development and quality performance use.1.4 Color-hold guidelines are presently limited to white, grey, beige, light brown, and dark brown (see Figs. X1.1 through X1.5). Additional colors will be added as color guidelines are developed.1.5 The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are for information only.NOTE 3: There is no known ISO equivalent to this standard.1.6 The text of this standard references notes and footnotes, which provide explanatory material. These notes and footnotes (excluding those in tables and figures) shall not be considered as requirements of this standard.1.7 The following safety hazards caveat pertains only to the test methods portion, Section 11, of this specification: 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.1.8 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.
