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.

This specification covers the chemical, mechanical, and dimensional requirements for wrought seamless nickel-titanium shape memory alloy tubes used for the manufacture of medical devices and surgical implants. Tubes shall be furnished in the superelastic condition, and the outer surface shall have a pickled, ground, or mechanically polished finish, or as agreed upon between purchaser and supplier. This specification addresses those product variables that differentiate drawn medical grade tube from the raw material and mill product forms. This specification applies precisely to tube with 10 mm (0.4 in.) and smaller nominal outside diameter and 2 mm (0.08 in.) and thinner nominal wall thickness. The mechanical properties to which the tubes shall conform are ultimate tensile strength (UTS), uniform elongation, upper plateau strength, lower plateau strength, and residual elongation.1.1 This specification covers the requirements for wrought nickel-titanium shape memory alloy tube, nominally 54.5 to 57.0 mass/mass (weight) % nickel, in the superelastic condition, used for the manufacture of medical devices and surgical implants. Material shall conform to the applicable requirements of Specification F2063. This specification addresses those product variables that differentiate drawn medical grade tube from the raw material and mill product forms covered in Specification F2063.1.2 This specification applies to tube with 10 mm (0.4 in.) and smaller nominal outside diameter and 2 mm (0.08 in.) and thinner nominal wall thickness.1.3 The values stated in SI units are to be regarded as the standard. The values given in parentheses (inch-pound units) are for information only.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.

This specification covers the chemical, physical, mechanical, and metallurgical requirements for wrought nickel-titanium bar, flat rolled products, and tubing containing nominally 54.5 % to 57.0 % nickel and used for the manufacture of medical devices and surgical implants. The material shall be made from ingot made from nickel and titanium with no other intentional alloy additions. The material shall be vacuum or inert atmosphere melted to control metallurgical cleanliness and alloy chemistry. Bar, plate, and tubing shall be supplied as hot finished or cold finished and annealed or heat treated. Surface condition may be oxidized, descaled, pickled, blasted, machined, ground, mechanically polished, or electropolished. Major elements shall be analyzed by direct current plasma spectrometry, atomic absorption, inductively coupled plasma spectrometry, X-ray spectrometer, glow discharge mass spectrometry, or an equivalent method. Carbon shall be measured by combustion and hydrogen shall be measured by inert gas fusion or vacuum hot extraction. Nitrogen and oxygen shall be measured by inert gas fusion. The nickel and titanium contents of nickel-titanium shape memory alloys cannot be measured to a precision required to guarantee shape memory or superelastic properties. Calorimetry or an equivalent thermomechanical test method must be used to assure the alloy formulation in terms of transformation temperature. Mechanical properties of the samples such as tensile strength and elongation shall be determined after annealing.1.1 This specification covers the chemical, physical, mechanical, and metallurgical requirements for wrought nickel-titanium bar, flat rolled products, and tubes containing nominally 54.5- to 57.0-weight percent nickel and used for the manufacture of medical devices and surgical implants.1.2 Requirements are for mill product, measuring 5.50 to 94.0 mm [0.218 to 3.70 in.] in diameter or thickness. Mill product is not intended to have the final shape, final surface finish, or final properties of the medical device, implant, or their components. Finished NiTi cold-worked tube should be considered under Specification F2633.1.3 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.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.

5.1 This test method provides a rapid, economical method for determination of transformation temperatures.5.2 Measurement of the specimen motion closely parallels many shape memory applications and provides a result that is applicable to the function of the material.5.3 This test method uses a wire, tube, strip specimen, or a wire, tube, or strip specimen extracted from a component; thus, it provides an assessment of a nickel titanium product in its semifinished or finished form.5.4 This test method may be used on annealed samples to determine the transformation temperatures and ensure the alloy formulation, since chemical analysis is not precise enough to adequately determine the nickel-to-titanium ratio of shape memory alloys.5.5 In general, the transformation temperatures measured by this method will not be the same as those measured by the DSC method defined in Test Method F2004. Therefore, the results of DSC and BFR cannot be compared directly.5.5.1 The BFR method measures the transformation temperatures by tracking shape recovery of stress-induced martensite deformed below the R′s temperature or the As temperature. In contrast, the DSC method measures the start, peak, and finish temperatures of the thermal transformation of martensite to R-phase or to austenite. See Refs (1-4).5.6 The test method is applicable to shape memory alloys with Af temperatures in the range of approximately –25 to 90 °C.1.1 This test method describes a procedure for quantitatively determining the martensite-to-austenite or the martensite to R-phase transformation temperature of annealed, aged, shape-set, or tempered nickel-titanium alloy specimens by deforming the specimen in bending and measuring the deformation recovered during heating through the thermal transformation (BFR method). See 3.1.1.NOTE 1: For aged, shape-set, or tempered specimens the transformation may be from martensite to austenite or from martensite to R-phase. See Reference (1)2 for details.1.2 The test specimen may be wire, tube, or strip or a specimen extracted from a semifinished or finished component.1.2.1 For specimens not in the form of a wire, tube, or strip that are extracted from semifinished or finished components, a wire, tube, or strip shaped test specimen shall be made from the component such that the deformation mode in the test specimen is pure bending.1.2.2 Other specimen geometries or displacements resulting in a more complex strain state, such as bending with torsion or buckling, are beyond the scope of this standard.1.3 Ruggedness tests have demonstrated that sample Af must be limited to obtain good test results. See 5.6 for details. Ruggedness tests have demonstrated that deformation strain, deformation temperature, and equilibration time at the deformation temperature must be controlled to obtain good test results. See 9.1, 9.2, and 9.4 for details.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 nonconformance with this standard.1.5 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.
