This specification covers track-resistant black thermoplastic high-density polyethylene insulation for conducting wires and cables operating continuously at a specified conductor temperature. The insulation is suitable for use for power transmission in overhead spaced-line service that is exposed to sunlight and other atmospheric environments. The prescribed tests cannot be performed unless the insulation is formed around a conductor, but these are done solely to determine the insulation properties and not to test the conductor or completed cable. Each test sample should be subjected to an ac or dc voltage withstand test at voltages that are based on the nominal thickness of the insulation and should comply with the required values for aging, heat distortion, cold blend, U-bend discharge, track resistance, tensile strength, elongation at rupture, environmental cracking, and surface resistivity.1.1 This specification covers track-resistant thermoplastic high-density polyethylene insulation. Before application to the conductor, the insulation shall comply with the requirements of Specification D1248, Type III, Class C or D, Category 5, Grade E10, J4, or J5. The requirements of Specification D1248 shall not apply to the insulation removed from the conductor.1.2 This type of insulation is considered suitable for use on wire or cable that will be used for continuous operation at conductor temperatures up to 75 °C.1.3 This insulation is suitable for use on wire or in cable used for power transmission in overhead spaced-line service, installed at temperatures above −25 °C and exposed to sunlight and other atmospheric environments between −55 and +75 °C.1.4 In many instances, the insulation cannot be tested unless it has been formed around a conductor. Therefore, tests done on insulated wire in this standard are solely to determine the relevant property of the insulation and not to test the conductor or completed cable.1.5 Whenever two sets of values are presented, in different units, the values in the first set are to be regarded as standard. The values given in parentheses are mathematical conversions that are provided for information only and are not considered standard.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.

1.1 This specification covers a type of plastic lumber product, defined as polyethylene-based structural-grade plastic lumber (SGPL), for use as main framing members, including joists, stringers, beams, columns; and secondary framing members, including planking, posts and bracing; in outdoor structures such as decks, boardwalks, docks, and platforms.1.2 This specification is applicable to solid, rectangular SGPL products where polyethylene resin (non cross-linked) is the continuous phase and is at least 50 % of the product (by weight).1.3 This specification is not applicable to plastic lumber products containing cellulosic materials as additives, fillers or fiber reinforcements.1.4 SGPL products covered by this specification shall not be used as tensile members.1.5 SGPL products are produced using several different manufacturing processes. These processes utilize a number of polyethylene resin material systems that include varying proportions of fillers, fiber reinforcements, and other chemical additives.1.6 Due to thermodynamic effects that result in outer-surface densification during manufacture, SGPL products are typically non-homogeneous in the cross-section. This standard does not address materials that have been modified from their original cross-section.1.6.1 The cross-section non-homogeneity is addressed in the material property assessments in this document only for applications in which the product cross-section is not modified by cutting, notching, or drilling. For products modified in this manner, additional engineering considerations are required and they are beyond the scope of this document.1.7 For purposes of this standard, an SGPL product is a specific combination of polyethylene resin, together with fillers, reinforcements, and additives. Each formulation is to be identified as a distinct and different product, to be tested and evaluated separately.1.8 Diverse and multiple combinations of both virgin and recycled polyethylene material systems are permitted in the manufacture of SGPL products.1.9 Fiber reinforcements used in SGPL include manufactured materials such as fiberglass (chopped or continuous), carbon, aramid and other polymeric materials.1.10 A wide variety of chemical additives are typically added to SGPL formulations. Examples include colorants, chemical foaming agents, ultraviolet stabilizers, fire retardants, lubricants, anti-static products, heat stabilizers, and coupling agents.1.11 Diverse types and combinations of filler systems are permitted in the manufacturing of SGPL products. Fillers that cause the product to fail the requirements of 6.13 are not permitted in the manufacturing of SGPL products.1.12 In order for a product to be classified as SGPL, it must meet the minimum stress and modulus criteria consistent with the specific product as marked, and additionally the properties specified in Section 6 of this specification.1.13 This specification pertains to SGPL where any reinforcement is uniformly distributed within the product. When reinforcement is not uniformly distributed, the engineering issues become substantially more complex. For this reason, such products are not covered in this document.1.14 Products that fail at strains of less than 0.02 (2 %) when tested in flexure in accordance with 6.6 are not compatible with the underlying assumptions of Annex A1 and are beyond the scope of this standard (see Note 1).NOTE 1: Calculation of time-dependent properties in Annex A1 is based on the assumption that the product does not fail in a brittle manner. The 2 % strain limit was selected based on the judgment of the task group members that created Annex A1.1.15 This specification addresses issues relevant to a buyer’s requirements for SGPL products and has therefore been developed in the format of a procurement specification.1.16 Criteria for design are included as part of this specification for SGPL products.1.17 Use of SGPL members in application will typically require the design of structural connections. Connection design between SGPL members falls outside the scope of this standard.1.18 The values are stated in inch-pound units, as these are currently the most common units used by the US construction industry. Equivalent SI units are indicated in parentheses.1.19 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.NOTE 2: There is no known ISO equivalent to this standard.1.20 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.

4.1 Full-encirclement-type band clamps are recommended for repairs only where the pipe is able to maintain its structural integrity. These clamps are not recommended for permanent repair of pipe where the damage could propagate outside the clamp under anticipated field conditions (see 5.1.1 for repair limitations). In such situations, it is recommended to cut out and replace the damaged pipe with a new piece. Clamps that are used for repair should comply with the manufacturer’s specifications for use and the manufacturer’s installation instructions should be followed.4.2 These clamps may be used to cover holes left in the pipe from abandoned service line connections, purge points, and accidental punctures.4.3 These clamps may be used to reinforce the pipe where the wall thickness has been reduced because of gouges or other irregularities.4.4 Some users reinforce polyethylene pipe after it has been squeezed-off as a precaution against pipe damage that may have occurred during the squeeze-off process and as a means of ensuring that the pipe will not be squeezed-off again at the same location. Consult with the polyethylene pipe manufacturer as to the appropriateness of squeeze-off for their product, and for circumstances when reinforcement is recommended. See Guide F1041.1.1 This guide specifically addresses the design and installation of full-encirclement-type band clamps for repair of gouges, punctures, or holes, and for reinforcement of polyethylene plastic pipe. Guidelines are provided for selecting and using clamps in pipe sizes 2 in. nominal (60 mm) and larger.1.1.1 A test method is also provided for the user to assess the applicability of the repair clamp. Under appropriate circumstances, this type of clamp offers a convenient, effective, and safe means of restoring the integrity of an in-service pipeline, without cutting out a section of pipe (see Note 1). The pipe to be repaired cannot be backed by a stiffener for internal support and cross-sectional dimensional control. Satisfactory use of this type of clamp should rely on the crush resistance of the pipe itself and a fitting design concept, which retains the cross-sectional pipe configuration while minimizing compressive forces required to obtain an effective leakage seal.NOTE 1: The appropriateness for use of this type of clamp should be determined by using the information contained in this guide and from consultation with, and recommendations of, both the pipe and clamp manufacturers. The basic premise for use of this type of clamp is that it is recommended by the manufacturer for this specific application and that step-by-step installation instructions are available for that application. It is important in the development of this type of clamp that prototype testing be conducted to evaluate performance expectations because of the physical limitations encountered when designing it for use with plastic pipe.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 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.
