5.1 This practice applies to materials manufactured in accordance with Specification C1729 (aluminum jacketing) or Specification C1767 (stainless steel jacketing). This standard is intended to provide a basic practice for installing these types of materials. Refer to Specifications C1729 and C1767 for information on the differences between aluminum and stainless steel jacketing and where each is considered for use.5.2 This practice is not intended to cover all aspects associated with installation for all applications, including factory and field fabricated pipe fitting covers.NOTE 1: Consult the National Commercial & Industrial Insulation Standards (MICA), Guide C1696, the product manufacturer, and/or project specifications for additional recommendations.5.3 Metal jacketing is typically used on insulated piping located outdoors, including, but not limited to, process areas and rooftops. Metal jacketing is used indoors where greater resistance to physical damage is required, for appearance, for improved fire performance, or as otherwise preferred. Metal jacketing used outdoors serves the same functions as indoors and also protects the insulation system from weather.5.4 Metal jacketing is used over all types of pipe insulation materials.1.1 This practice covers recommended installation techniques for aluminum and stainless steel jacketing for thermal and acoustic pipe insulation operating at either above or below ambient temperatures and in both indoor and outdoor locations. This practice applies to materials manufactured in accordance with Specification C1729 (aluminum jacketing) or Specification C1767 (stainless steel jacketing). It does not address insulation jacketing made from other materials such as mastics, fiber-reinforced plastic, laminate jacketing, PVC, or rubberized or modified asphalt jacketing, nor does it cover the details of thermal or acoustical insulation systems.1.2 The purpose of this practice is to optimize the performance and longevity of installed metal jacketing and to minimize water intrusion through the metal jacketing system. This document is limited to installation procedures for metal jacketing over pipe insulation up to a pipe size of 48 in. NPS and does not encompass system design. This practice does not cover the installation of metal jacketing on rectangular ducts or around valves and gauges. It excludes the installation of spiral jacketing on cylindrical insulated ducts but is applicable to metal jacketing on cylindrical insulated ducts installed similarly to pipe insulation jacketing. Guide C1423 provides guidance in selecting jacketing materials and their safe use.1.3 For the purposes of this practice, it is assumed that the aluminum or stainless steel jacketing is of the correct size necessary to cover the thermal insulation system on the pipe or rigid tubing while achieving the longitudinal overlaps specified in 8.2.2 and 8.3.2. The size of the aluminum or stainless steel jacket necessary to achieve this specified longitudinal overlap closure is a complex topic for which the detailed requirements are outside the scope of this practice. Achieving this fit is very important to the performance of the total insulation system. See Appendix X1 for general information and recommendations regarding this closure of aluminum and stainless steel jacketing installed over thermal pipe and rigid tubing insulation.1.4 The intrusion of water or water vapor into an insulation system will, in some cases, cause undesirable results such as corrosion under insulation, loss of insulating ability, and physical damage to the insulation system. Minimizing the movement of water through the metal jacketing system is only one of the important factors in helping maintain good long-term performance of the total insulation system. There are many other important factors including proper performance and installation of the insulation, vapor retarder, and insulation joint sealant. Optimum long-term insulation system performance is only achieved by carefully considering all aspects of insulation system design and how these relate to the intended application (hot, cold, cryogenic, severe environment, etc.). This practice only addresses installation of metal jacketing so total insulation system design is outside of its scope.1.5 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.1.6 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.

4.1 This test method establishes the short term hydraulic failure pressure of thermoplastic pipe, tubing and fittings, and reinforced thermosetting pipe, and reinforced thermoplastic pipe. Data obtained by this test method are of use only in predicting the behavior of pipe, tubing, and fittings under conditions of temperature, time, method of loading, and hoop stress similar to those used in the actual test. They are generally not indicative of the long-term strength of thermoplastic or reinforced thermosetting resin pipe, tubing, and fittings, and reinforced thermoplastic pipe.4.2 Procurement specifications utilizing this test method may stipulate a minimum and maximum time for failure other than the 60 to 70 s listed in 9.1.3. Either the internal hydraulic pressure or the hoop stress may be listed in the requirements.NOTE 2: Many thermoplastics give significantly different burst strengths depending on the time to failure. For instance, significant differences have been observed between failure times of 65 and 85 s.4.3 This test method is also used as a short-term pressurization validation procedure, where the specimens are pressurized to a predetermined minimum pressure requirement.1.1 This test method covers the determination of the resistance of thermoplastic pipe, tubing and fittings, and reinforced thermosetting pipe and reinforced thermoplastic pipe to hydraulic pressure in a short time period. Procedure A is used to determine burst pressure of a specimen if the mode of failure is to be determined. Procedure B is used to determine that a specimen complies with a minimum burst requirement.NOTE 1: Reinforced thermoplastic pipe is a three-layer construction consisting of a thermoplastic core layer around which is wound a continuous helical reinforcement layer. A protective thermoplastic cover layer is applied over the reinforcement. For design and pressure, the thermoplastic core and cover layers are not considered hoop stress bearing elements. All of the hoop stress is taken up by the reinforcement layer.1.2 This test method is suitable for establishing laboratory testing requirements for quality control purposes or for procurement specifications.1.3 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.1.4 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.1.5 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.

5.1 Significance—With the birth of minimally invasive surgery in the 1960s, there has been a requirement for guide wires. The guide wires serve as the access line by which procedures like balloon angioplasty and stent placement are conducted. A guide wire typically consists of a mandrel, coil and in some cases a safety wire is used. The market for guide wires continues to grow as the number of procedures increases. For successful manufacturing of guide wires, linearity or straightness of 304 stainless steel and nitinol wire that is used for the manufacture of guide wire mandrels is critical to their end use performance. Users of guide wires require that they must navigate a tortuous anatomy.5.1.1 A second part of minimally invasive surgery is the use of machined or formed wire, tube, or rod. In this case, straightness of rod, tube, and wire that is going to be machined or subjected to a forming practice such as bending needs to be very linear or straight so it is accurately fed into the equipment that is used for the machining or forming practice. Laser machining is an example of a machining operation that requires a wobble-free piece of rod, tubing, or wire so that it can be properly fed into the alignment bushings of the laser. Wire forming equipment also requires wobble-free material for the same reason.5.2 Use—These test methods can be used by users and producers of medical grade bar, rod, tubing, and wire to specify requirements to evaluate and confirm the straightness of material. Depending upon the type of material and its metallurgical condition, it may be possible to reprocess the material to reduce its non-linearity.1.1 This standard covers the various test methods to be used for measurement of straightness of bar, rod, tubing, and wire. These test methods apply primarily to bar, rod, tubing, and wire that are ordered in the straightened and cut-to-length condition. They also apply to small diameter tubing and wire that has been specially processed to roll off a spool in the straightened condition.1.2 These test methods apply to straightness of round wire that has a diameter between 0.05 and 4.78 mm (0.002 and 0.188 in.). They also apply to flatness (camber) of flat-shaped wire or ribbon with a maximum dimension between 0.05 and 4.78 mm (0.002 and 0.188 in.). For flatness (camber) measurement, refer to Test Method F2754/F2754M.NOTE 1: The current version of Test Method F2754/F2754M covers a different diameter range (0.0127 to 4.78 mm (0.0005 to 0.188 in.)) and does not include superelastic NiTi. These exceptions would not affect the camber measurement as conducted by Test Method F2754/F2754M.1.3 These test methods apply to straightness of round tubing that has an outer diameter between 0.05 and 6.35 mm (0.002 and 0.25 in.).1.4 These test methods apply to straightness of round rod that has a diameter between 4.78 and 6.35 mm (0.188 and 0.25 in). It also applies to flatness (camber) of flat and shaped rod with a maximum dimension between 4.78 and 6.35 mm (0.188 and 0.25 in). For measurement of flatness (camber), refer to Test Method F2754/F2754M.NOTE 2: The current version of Test Method F2754/F2754M covers a different diameter range (0.0127 to 4.78 mm (0.0005 to 0.188 in.)) and does not include superelastic NiTi. These exceptions would not affect the camber measurement as conducted by Test Method F2754/F2754M.1.5 These test methods apply to straightness of round bar that has a diameter between 6.35 and 101.6 mm (0.25 and 4 in). It also applies to flatness (camber) of flat and shaped bar with a maximum dimension between 6.35 and 101.6 mm (0.25 and 4 in). For measurement of flatness (camber), refer to Test Method F2754/F2754M.NOTE 3: The current version of Test Method F2754/F2754M covers a different diameter range (0.0127 to 4.78 mm (0.0005 to 0.188 in.)) and does not include superelastic NiTi. These exceptions would not affect the camber measurement as conducted by Test Method F2754/F2754M.1.6 These test methods apply to ferrous and non-ferrous alloys including linear-elastic or superelastic nitinol. Refer to Terminology F2005 for more details on NiTi terminology.1.7 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.1.8 This standard does not purport to address all of the safety concerns, if any, associated with its use.

This guide covers standard specification for a number of grades of nominal-wall-thickness, welded ferritic and martensitic stainless steel tubing for general corrosion-resisting and high-temperature service. The steel shall conform to the required chemical composition for carbon, manganese, phosphorus, sulfur, silicon, nickel, chromium, molybdenum, aluminum, copper, nitrogen, titanium, and columbium. The number of tubes in a lot heat treated by the continuous process shall be determined from the size of the tubes. The steel shall conform to the following tensile properties: tensile strength, yield strength, and elongation. The tubes shall have a hardness number that will not exceed the prescribed Brinell and Rockwell hardness values. Several mechanical tests shall be conducted, namely: tension test; flaring test (for seamless tubes); flange test (for welded tubes); hardness test; reverse flattening test; intergranular corrosion test; and hydrostatic or nondestructive electric test.1.1 This specification2 covers a number of grades of nominal-wall-thickness, stainless steel tubing for general corrosion-resisting and high-temperature service. Most of these grades are commonly known as the “straight-chromium” types and are characterized by being ferromagnetic. Two of these grades, TP410 and UNS S 41500 (Table 1), are amenable to hardening by heat treatment, and the high-chromium, ferritic alloys are sensitive to notch-brittleness on slow cooling to ordinary temperatures. These features should be recognized in the use of these materials.TABLE 1  ContinuedGrade TP439 . . . . . . TP430 Ti TPXM-27 TPXM-33A 18Cr-2Mo 29-4 29-4-2 26-3-3 25-4-4 ... . . . . . . . . . . . .

Within the text, the SI units are shown in brackets. 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. The inch-pound units shall apply unless the “M” designation of this specification is specified in the order.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.
