Materials shall be measured using techniques in accordance with the following test methods: impact testing; deflection temperature under load; tensile stress at yield point; modulus of elasticity in tension; and specific gravity.1.1 This classification system covers materials made from only virgin ABS polymers and blends of ABS polymers suitable for use in the extrusion of pipe and molding of fittings.1.2 The requirements of this classification system are applicable only to the ABS polymers and blends of ABS polymers as classified and do not address the requirements of the finished pipe or fittings. The applicable ASTM standard specification for pipe or fittings shall be consulted for their requirements.1.3 This classification system excludes ABS polymers and blends of ABS polymers made from reprocessed, regrind, reclaimed, or recycled materials. ABS rework, generated in-house by the original plastic manufacturer, is allowed to be used by that original manufacturer, provided the ABS product shipped meets the physical and mechanical properties required by its callout in Table 1.1.4 This classification system and subsequent line callout (specification) provides a means for describing ABS materials used in the manufacture of pipe and fittings. It is not intended for the selection of materials. Material selection shall be made by those having expertise in the plastics field after careful consideration of the design and the performance required of the part, the environment to which it will be exposed, the fabrication process to be employed, the inherent properties of the material other than those covered by this classification system, and the economics.1.5 This classification system and subsequent line callout (specification) provides for the classification of ABS polymers and blends of ABS polymers into groups based on five properties: Izod impact strength at room temperature, Izod impact strength at low temperature, deflection temperature under load, tensile stress at yield point, and modulus of elasticity in tension.

5.1 This practice is useful for establishing the hoop stress or internal pressure versus time-to-failure relationships, under selected internal and external environments which simulate actual anticipated product end-use conditions, from which a design basis for specific piping products and materials can be obtained. This practice defines an HDB for material in straight, hollow cylindrical shapes where hoop stress can be easily calculated, and a PDB for fittings and joints where stresses are more complex.5.1.1 An alternative design practice based on initial strain versus time-to-failure relationships employs a strain basis HDB instead of the stress basis HDB defined by this practice. The strain basis HDB is most often used for buried pipe designs with internal pressures ranging from 0 to 250 psig (1.72 MPa).5.2 To characterize fiberglass piping products, it is necessary to establish the stress versus cycles or time to failure, or pressure versus cycles or time to failure relationships over three or more logarithmic decades of time (cycles or hours) within controlled environmental parameters. Because of the nature of the test and specimens employed, no single line can adequately represent the data. Therefore, the confidence limits shall be established.5.3 Pressure ratings for piping of various dimensions at each temperature may be calculated using the HDS determined by testing one size of piping provided that the same specific process and material are used both for test specimens and the piping in question.5.4 Pressure ratings at each temperature for components other than straight hollow shapes may be calculated using the HDP determined by testing one size of piping provided that (1) the specific materials and manufacturing process used for the test specimens are used for the components, (2) for joints, the joining materials and procedures used to prepare the test specimens are used for field joining, and (3) scaling of critical dimensions is related to diameter and pressure rating of the component.NOTE 10: Scaling of fittings and joints should be further verified by short-time testing in accordance with Test Method D1599.5.5 Results obtained at one set of environmental conditions shall not be used for other conditions, except that higher temperature data can be used for design basis assignment for lower application temperatures. The design basis shall be determined for each specific piping product. Design and processing can significantly affect the long-term performance of piping products, and therefore shall be taken into consideration during any evaluation.5.6 This practice is valid for a given pipe or fitting only so long as the specimens are truly representative of that material and manufacturing process.5.6.1 Changes in materials or manufacturing processes will necessitate a reevaluation as described in Section 12.1.1 This practice establishes two procedures, Procedure A (cyclic) and Procedure B (static), for obtaining a hydrostatic design basis (HDB) or a pressure design basis (PDB) for fiberglass piping products, by evaluating strength-regression data derived from testing pipe or fittings, or both, of the same materials and construction, either separately or in assemblies. Both glass-fiber-reinforced thermosetting-resin pipe (RTRP) and glass-fiber-reinforced polymer mortar pipe (RPMP) are fiberglass pipe.NOTE 1: For the purposes of this standard, polymer does not include natural polymers.1.2 This practice can be used for the HDB determination for fiberglass pipe where the ratio of outside diameter to wall thickness is 10:1 or more.NOTE 2: This limitation, based on thin-wall pipe design theory, serves further to limit the application of this practice to internal pressures which, by the hoop-stress equation, are approximately 20 % of the derived hydrostatic design stress (HDS). For example, if HDS is 5000 psi (34 500 kPa), the pipe is limited to about 1000-psig (6900-kPa) internal pressure, regardless of diameter.NOTE 3: Where long (continuous) glass fibers are intentionally placed to resist the planned pressure load case (that is, free end pressure testing and 654.7° fiberglass windings) the results from this practice may be overly conservative in predicting long term fiberglass pipe performance when the same pipe is operated at lower (non-damaging) stresses typical in normal pipeline applications.NOTE 4: All data points in the analysis shall be of the same failure mode. Where plastic creep of the resin leading to pipe failure is precluded by unintended resin matrix cracking or other unanticipated modes of failure, this practice may not accurately represent the pipe’s life expectancy.1.3 This practice provides a PDB for complex-shaped products or systems where complex stress fields seriously inhibit the use of hoop stress.1.4 Specimen end closures in the underlying test methods may be either restrained or free, leading to certain limitations.1.4.1 Restrained Ends—Specimens are stressed by internal pressure only in the hoop direction, and the HDB is applicable for stresses developed only in the hoop direction.1.4.2 Free Ends—Specimens are stressed by internal pressure in both hoop and longitudinal directions, such that the hoop stress is twice as large as the longitudinal stress. This practice may not be applicable for evaluating stresses induced by loadings where the longitudinal stress exceeds 50 % of the HDS.1.5 The values stated in inch-pound units are to be regarded as the standard. The values in parentheses are given for information purposes only.NOTE 5: There is no known ISO equivalent to this 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.1.7 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 classification of sulfone plastics suitable for injection molding and extrusion. It is intended to be a means of calling out sulfone plastics used in the fabrication of end items or parts. Sulfone polymers, being thermoplastic, are reprocessable and recyclable. All of the sulfone polymers which are under this specification contain ether oxygen which is a necessary component of the polymers as in the diphenyl sulfone moiety. Examples of moieties which can be part of the backbone of the repeating unit, in addition to diphenyl sulfone, are diphenyl isopropylidene, and biphenyl. Blends of these polymers can exist as well as co- and ter-polymers. Commercial polymers that are members of this class of thermoplastics include polysulfone (PSU), polyether sulfone (PESU), and polyphenylsulfone (PPSU). Unreinforced sulfone plastics are classified into groups in accordance with their composition. The classes and grades in which these groups are subdivided are shown in this specification. The plastic shall be tested for deflection temperature, Izod impact, and solution viscosity.1.1 This classification system covers sulfone plastics suitable for injection molding and extrusion. Sulfone polymers, being thermoplastic, are reprocessable and recyclable. This classification system allows for the use of reprocessed or recycled sulfone polymer materials.1.2 The properties included in this standard are those required to identify the compositions covered. Other requirements necessary to identify particular characteristics important to specialized applications are to be specified by using the suffixes in Section 5. See Guide D5740.1.3 This classification system and subsequent line callout (specification) are intended to provide a means of calling out sulfone plastics used in the fabrication of end items or parts. It is not intended for the selection of materials. Material selection can be made by those having expertise in the plastics field only after careful consideration of the design and the performance required of the part, the environment to which it will be exposed, the fabrication process to be employed, the costs involved, and the inherent properties of the material other than those covered by this standard.1.4 The following safety hazards caveat pertains only to the test method portion, Section 11, of this classification system: 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 1: Reference Guide D7209 for information and definitions related to recycled plastics.NOTE 2: ISO 24025 is similar in subject matter but not equivalent to this standard.1.5 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.
