5.1 The procedures described in Section 8 are intended for butt-fusion joining of CX-PE pipe and tubing, using suitable equipment and appropriate environmental control procedures. Appropriate controls are established on the butt-fusion joining process to ensure that the pipe is suitable for joining, that the operator is properly trained, that adequate apparatus and procedures are used, and that the process is protected from environmental extremes. The controls are established by testing butt-fusion joints, operator skills, the apparatus and the procedures used. When this practice is properly implemented, strong pressure and leak-tight joints are produced. When joints made in accordance with this practice are destructively tested, failures are expected to occur outside the fusion-joined area.5.1.1 This practice shall not be used to join PEX pipe or tubing made in accordance with Specification F876 or any other PEX pipe or system specification. This practice is not intended to be used for pipe or tubing to be crosslinked by radiation or by using peroxides. This practice shall not be used to join CX-PE pipe that has been commissioned. CX-PE pipe that has been commissioned is crosslinked pipe.5.2 Melt characteristics, average molecular weight and molecular weight distribution are influential factors in establishing suitable fusion parameters, therefore, consider the manufacturers instructions in the use or development of a specific fusion procedure.5.3 The butt fusion procedures in this practice are suitable for joining CX-PE pipe and tubing that is used in pressure, low pressure, and non-pressure applications. For some applications, qualification of the procedure by testing joints made using the procedure in accordance with regulations from the authority having jurisdiction are required.5.4 This butt-fusion joining practice shall only be used to join pipe or tubing made from compatible CX-PE compounds and meeting the same specification dimensions for outside diameter and wall.1.1 This practice describes procedures for making butt fusion joints with crosslinkable polyethylene (CX-PE) pipe and tubing2 which is less than 30 % crosslinked at the time of joining. This practice shall not be applied to crosslinked products, that is PEX pipe or tubing or to CX-PE after commissioning3 (commissioning transitions CX-PE pipe into crosslinked pipe).NOTE 1: For avoidance of doubt, CX-PE is a completely different product than PEX, especially for the purposes of butt-fusion joining and the fabrication of fittings. The two must not be confused by the reader of this standard.1.2 The main difference between this practice and Practice F2620 is that the production date of pipe must be checked prior to butt fusion. Field experiments have indicated that it is best to make heat fused joints before the pipe has aged six months to ensure it has not crosslinked more than 30 % at ambient conditions. (See 7.2.)1.3 Joints are made by means of butt-fusion joining in, but not limited to, a field environment. Other suitable butt-fusion joining procedures may be available from various sources including pipe and fitting manufacturers. This practice does not claim to address all possible butt-fusion joining procedures and does not prevent the use of qualified procedures developed by other parties that have been proven to produce reliable butt fusion joints.1.4 The parameters and procedures set forth in this practice are applicable to the butt-fusion joining of CX-PE pipe and tubing. Consult with the manufacturers of CX-PE pipe or tubing to ensure that they approve of the use of this practice for butt-fusion joining of their products. This practice applies to butt fusion of both CX-PE pipe and tubing even when tubing is not explicitly referred to.1.5 CX-PE pipe or tubing is required to produce sound joints when using the joining procedures described in this practice. Component ends joined in accordance with this practice shall be of the same nominal diameter and wall thickness.1.6 The ability to join pipe using this practice does not imply that the pipe joined is suitable for any intended use.1.7 This practice does not purport to address any issues related to the commissioning of a CX-PE system prior to its use. The intention of this standard practice is to set forth requirements for the butt fusion of CX-PE pipe and tubing which when followed are expected to yield durable joints in the said pipe and tubing.1.8 Only procedures related to butt-fusion joining are covered in this practice. Saddle fusion and socket fusion are not included in this practice.1.9 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.1.10 The text of this practice references notes, footnotes, and appendixes which provide explanatory material. These notes and footnotes (excluding those in tables and figures) shall not be considered as requirements of the practice.1.11 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.1.12 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.

X1.2 SignificanceX1.2.1 Concentrations of trace metals are measured as extracts in simulated body fluids. The metal’s concentration in extracts is based on the surface area of the plastic extracted from which the total amount of metal deliverable to the patient may be estimated.AbstractThis specification covers the properties for polyethylene plastics for use in medical device applications involving human tissue contact devices, short term indwellings, and fluid transfer devices. Biocompatibility tests must be conducted on the final products as the biocompatibility of these materials as a class has not been established. Plyethylene plastics should consist of basic polymers with ethylene as essentially the sole monomer. The compound may contain optional adjuvant substances required in polymer production or fabrication. The final compound should yield a consistent absorption spectrum characteristic of the established formulation. The polyethylene plastics should be tested using the specified physical test procedures for density, melt flow, tensile properties, compressive properties, stiffness, flexural fatigue, and other flexural properties.1.1 This specification covers polyethylene plastics (as defined in Terminology D883) intended for use in medical device applications involving human tissue contact devices, short-term indwellings of 30 days or less, and fluid transfer devices. The biocompatibility of these materials as a class has not been established. Biocompatibility tests must be conducted on the final product.1.2 This specification is not applicable to ultra-high molecular weight polyethylenes (UHMWPE) plastics, such as those used in joint implants, and so forth.1.3 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this 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 and health practices and determine the applicability of regulatory limitations prior to use.

5.1 Environment or oxidative time-to-fail data derived from this test method, analyzed in accordance with Section 13, are suitable for extrapolation to typical end-use temperatures and hoop stresses. The extrapolated value(s) provides a relative indication of the resistance of the tested PE pipe or system to the oxidative effects of chlorinated water for conditions equivalent to those conditions under which the test data were obtained. The performance of a material or piping product under actual conditions of installation and use is dependent upon a number of factors including installation methods, use patterns, water quality, nature and magnitude of localized stresses, and other variables of an actual, operating cold water supply or service system that are not addressed in this test method. As such, the extrapolated values do not constitute a representation that a PE pipe or system with a given extrapolated time-to-failure value will perform for that period of time under actual use conditions.5.2 This test method has been generally used for evaluating oxidatively induced Stage II or Stage III failure data.1.1 This test method describes the general requirements for evaluating the long-term, chlorinated water, oxidative resistance of polyethylene (PE), used in cold water supply or service systems by exposure to chlorinated water. This test method outlines the requirements of a pressurized flow-through test system, typical test pressures, test-fluid characteristics, failure type, and data analysis.NOTE 1: Other known disinfecting systems (chlorine dioxide, ozone, and chloramine) are currently used for protection of potable water; however, free-chlorine is by far the most common system in use today. Disinfecting systems other than chlorine have not been evaluated by this method.1.2 Guidelines and requirements for test temperatures, test hoop stresses, and other test criteria have been established by prior testing of PE pipe. Other related system components that typically appear in a PE cold water supply or service system can be evaluated with the PE pipe. When testing PE pipe and fittings as a system, it is recommended that the anticipated end-use fitting type(s) and material(s) be included in the test circuit since it is known that some fitting types and materials can impact failure times. Specimens used shall be representative of the piping product(s) and material(s) under investigation.NOTE 2: The procedures described in this test method (with some modifications of test temperatures or stresses, or both) have been used to evaluate pipes manufactured from polybutylene (PB), crosslinked polyethylene (PEX), polypropylene (PP), multilayer (polymer-metal composite), copper, and stainless steel.1.3 This test method is applicable to PE pipe and systems used for transport of potable water containing free-chlorine for disinfecting purposes. The oxidizing potential of the test-fluid specified in this test method exceeds that typically found in potable water systems across the United States.1.4 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.1.5 The following precautionary caveat pertains only to the test method portion, Section 12, of this specification.This standard does not purport to address all of the safety concerns, if any, associated with its use.
