ASTM D3296-24(Specification)
Standard Specification for FEP Resin Tube

ABSTRACT
This specification covers the tubing that is intended for electrical, mechanical, chemical and medical applications manufactured from extrusion resins made from the copolymer of tetrafluoroethylene and hexafluoropropylene. Three types of FEP-fluorocarbon tubing are classified which are differentiated by size schedules: Type I which is tubing based upon the American wire gage, Type II which is tubing based upon fractional inch sizes, and Type III which is tubing of all other sizes. Tubings are further differentiated in accordance to its increasing wall thicknesses in classes which are Class A, Class C, Class D, and Class E. Several properties of tubing such as inside diameter, wall thickness, specific gravity, tensile strength, elongation, dielectric breakdown voltage, dimensional stability, and heat resistance shall be determined by subjecting it to different test methods.
SCOPE
1.1 The tubing is intended for electrical, mechanical, chemical, and medical applications manufactured from extrusion resins made from the copolymer of tetrafluoroethylene and hexafluoropropylene or modified FEP resins containing no more than 2 % by weight of other fluoromonomers. This specification is for virgin material only and does not address recycled material as it is not appropriate for FEP tubing.  
Note 1: Abbreviations are in accordance with Terminology D1600.
Note 2: There is no known ISO equivalent to this standard.  
1.2 The values stated in SI units are to be regarded as the standard. The values given in parentheses are for information only.  
1.3 The following safety hazards caveat pertains only to the test methods portion, Section 8, 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.  
1.4 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.

ASTM D2924-24(Test Method)
Standard Test Method for External Pressure Resistance of “Fiberglass” (Glass-Fiber-Reinforced Thermosetting-Resin) Pipe

SIGNIFICANCE AND USE
5.1 The values obtained by this test method are applicable only to conditions that specifically duplicate the procedures used.  
5.2 After a scaling constant is determined for one diameter, this may be used for calculating the external failure pressures of other diameters as long as the resin and reinforcement (if used), the wall thickness-to-diameter ratio, and the reinforcement pattern (if reinforcement is used) are the same.  
Note 3: Based upon tests conducted on one size of pipe, a scaling constant is calculated according to 10.1 or 10.2. The appropriate constant is used to calculate failure pressure for other pipe diameters, but it can only be applied if the same resin and reinforcement are used, the wall thickness to diameter ratios are similar, and the reinforcement pattern is constant.  
5.3 In the application of the following test requirements and recommendations, care must be exercised to ensure that the specimens tested are truly representative of the group being studied.
SCOPE
1.1 This test method covers determination of the resistance of fiberglass pipe to external pressure. It classifies failures as buckling, compressive, and leaking. Both glass-fiber-reinforced thermosetting-resin pipe (RTRP) and glass-fiber-reinforced polymer mortar pipe (RPMP) are fiberglass pipes.
Note 1: For the purposes of this standard, polymer does not include natural polymers.  
1.2 The values stated in inch-pound units are to be regarded as standard. The SI units given in parentheses are for information only.  
Note 2: There is no known ISO equivalent to this 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.

ASTM D2996-23(Specification)
Standard Specification for Filament-Wound “Fiberglass” (Glass-Fiber-Reinforced Thermosetting-Resin) Pipe

ABSTRACT
This specification covers machine-made reinforced thermosetting resin pressure pipe (RTRP) manufactured by the filament winding process. This specification does not include reinforced polymer mortar pipe (RPMP), which is another type of fiberglass pipe. The pipes are generally classified by type, grade, class, and hydrostatic design. In addition, a secondary cell classification system defines the basic mechanical properties of the pipe. The resins, reinforcements, colorants, fillers, and other materials, when combined as a composite structure, shall produce a pipe that shall meet the performance requirements of this specification. Materials shall be tested and the individual grades shall conform to the specified values of dimensions and tolerances, long-term static hydrostatic strength, long-term cyclic hydrostatic strength, short-term hydrostatic failure strength, longitudinal tensile properties, and stiffness factor.
SCOPE
1.1 This specification covers machine-made reinforced thermosetting resin pressure pipe (RTRP) manufactured by the filament winding process up to 60 in. nominal size. Included are a classification system and requirements for materials, mechanical properties, dimensions, performance, methods of test, and marking.  
1.2 The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are provided for information purposes only.  
1.3 The following safety hazards caveat pertains only to the test method portion, Section 8, 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.
Note 1: The term “fiberglass pipe” as described in Section 3 of this specification applies to both reinforced thermosetting resin pipe (RTRP) and reinforced polymer mortar pipe (RPMP). This specification covers only reinforced thermosetting resin pipe (RTRP).
Note 2: There is no known ISO equivalent to this standard.
Note 3: This specification is applicable to RTRP where the ratio of outside diameter to wall thickness is 10:1 or more.
Note 4: For the purposes of this standard, polymer does not include natural polymers.  
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.

ASTM
ASTM D3681-23(Test Method)
Standard Test Method for Chemical Resistance of “Fiberglass” (Glass–Fiber–Reinforced Thermosetting-Resin) Pipe in a Deflected Condition

SIGNIFICANCE AND USE
5.1 This test method evaluates the effect of a chemical environment on pipe when in a deflected condition. It has been found that effects of chemical environments can be accelerated by strain induced by deflection. This information is useful and necessary for the design and application of buried fiberglass pipe.  
Note 4: Pipe of the same diameter but of different wall thicknesses will develop different strains with the same deflection. Also, pipes having the same wall thickness but different constructions making up the wall may develop different strains with the same deflection.
SCOPE
1.1 This test method covers the procedure for determining the chemical-resistant properties of fiberglass pipe in a deflected condition for diameters 4 in. (102 mm) and larger. Both glass–fiber–reinforced thermosetting resin pipe (RTRP) and glass–fiber–reinforced polymer mortar pipe (RPMP) are fiberglass pipes.  
Note 1: For the purposes for this standard, polymer does not include natural polymers.  
1.2 Inch-pound units are to be regarded as the standard. The values given in parentheses are for information only.  
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. Specific precautionary statements are given in 9.5.
Note 2: There is no known ISO equivalent to this standard.  
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.

Standard Test Method for Long-Term Ring-Bending Strain of “Fiberglass” (Glass-Fiber-Reinforced Thermosetting-Resin) Pipe

SIGNIFICANCE AND USE
5.1 This test method determines the long-term ring-bending strain of pipe when deflected under constant load and immersed in a chemical environment. It has been found that effects of chemical environments can be accelerated by strain induced by deflection. This information is useful and necessary for the design and application of buried fiberglass pipe.  
Note 3: Pipe of the same diameter but of different wall thicknesses will develop different strains with the same deflection. Also, pipes having the same wall thickness but different constructions making up the wall may develop different strains with the same deflection.
SCOPE
1.1 This test method covers a procedure for determining the long-term ring-bending strain (Sb) of “fiberglass” pipe. Both glass-fiber-reinforced thermosetting-resin pipe (RTRP) and glass-fiber-reinforced polymer mortar pipe (RPMP) are “fiberglass” pipes.  
1.2 The values stated in inch-pound units are to be regarded as the standard. The SI units given in parentheses are for information only.  
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. A specific warning statement is given in 9.5.

ASTM D2992-22(Practice)
Standard Practice for Obtaining Hydrostatic or Pressure Design Basis for “Fiberglass” (Glass-Fiber-Reinforced Thermosetting-Resin) Pipe and Fittings

SIGNIFICANCE AND USE
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 ...
SCOPE
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 h...
