5.1 This standard practice is designed to specify the minimum training and testing required of HFE operators trainees before they obtain a Heat Fusion Equipment Operator Qualification card. It will allow the industry to require the “HFE” operators be trained and qualified to an approved procedure before they can heat fuse PE or PA pipe in the field. The standard practice will bring more competency in the operators and more consistency in the training they receive.1.1 This practice describes criteria for the training, assessment and qualification of heat fusion equipment (HFE) operators in, but not limited to, a field environment in order to establish and maintain competency in the joining of Polyethylene (PE) and Polyamide (PA) piping systems.1.2 This HFE operator training and qualification is applicable to heat fusion joining of PE pipe and fittings to other PE pipe and fittings of related polymer chemistry specified in the heat fusion procedures or standards used. It is also applicable to heat fusion joining of PA pipe and fittings to other PA pipe and fittings of the same polymer chemistry specified in the heat fusion procedures or standards used. The heat fusion between PE pipe and fittings to PA pipe and fittings is NOT allowed.1.3 The HFE operator training and qualification shall be for butt fusion for either PE or PA piping products, using the specific brand and size range of fusion machine to be used by the HFE operator and the heat fusion procedures or standards specified. If the HFE operator trainee requests, the training shall also include saddle and/or socket fusion of PE pipe and fittings of related polymer chemistry specified in the heat fusion procedures or standards used. This standard does not include training on the electro-fusion of these piping products.1.4 The HFE operator qualification shall be for one specific manufacturer’s fusion machine or a size range of that manufacturer’s hydraulic fusion machines or equipment that all operate in the same manner with the same hydraulic design and controls and the same heater and facer design. For smaller pipe sizes (6 in. and smaller), the qualification can be on a specific fusion machine or a combination of butt, saddle and/or socket fusion machines or equipment.1.5 The HFE operator qualification shall be on specific heat fusion procedures or standards specified for PE and PA pipes. For PE pipe and fittings, this shall include Practice F2620 or other company or pipe manufacturer’s procedures, or a combination thereof. For PA-11 pipe and fittings, this shall include Plastics Pipe Institute (PPI) Technical Report TR-45 or other company or pipe manufacturer’s procedures. For PA-12 pipe and fittings, this shall include Practice F3372 or other company or pipe manufacturer’s procedures, or a combination thereof. For other PA pipe materials, use other company or pipe manufacturer’s procedures.1.6 The values stated in inch-pound units are to be regarded as standard. No other units of measurement are included in this standard.1.7 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.1.8 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 Squeeze-off is widely used to temporarily control the flow of gas in PE pipe. Squeeze tools vary depending on the size of the pipe and the design of the tool. Squeeze-off procedures vary depending on the tool design, pipe material, and environmental conditions.5.2 Experience indicates that some combinations of polyethylene material, temperature, tool design, wall compression percentage and procedure can cause damage leading to failure.5.3 Studies of polyethylene pipe extruded in the late 1980s and thereafter show that damage typically does not develop when the wall compression percentage is 30 % or less, when temperatures are above 50 °F (10 °C), and when closure and release rates are typical of field conditions for screw-driven tools.4 With tools meeting Specification F1563, acceptable flow control at typical gas service pressures is achieved at wall compression percentages between 10 and 20 % for pipe diameters less than 6 in.4,5 Because damage does not develop in these materials at such squeeze levels, the references cited indicate that squeeze-off flow control practices using tools meeting Specification F1563 and qualified procedures meeting Practice F1041 are effective for smaller pipe sizes.4 ,5NOTE 3: Specification F1563 provides a procedure for evaluating tool flow control performance.5.4 This practice provides a method to qualify a combination of squeeze tool, pipe size and material, and squeeze-off procedure to ensure that long-term damage does not occur. This practice is useful for polyethylene gas pipe manufactured before 1975, for new or revised polyolefin gas pipe materials, for pipe diameters of 8 in. or above, for new or revised squeeze tool designs, and for new or revised squeeze-off procedures.1.1 This practice covers qualifying a combination of a squeeze tool, a polyethylene gas pipe, and a squeeze-off procedure to avoid long-term damage in polyethylene gas pipe. Qualifying is conducted by examining the inside and outside surfaces of pipe specimens at and near the squeeze to determine the existence of features indicative of long-term damage. If indicative features are absent, sustained pressure testing in accordance with Specification D2513 is conducted to confirm the viability of the squeeze-off process. For assistance with specimen examination, an Adjunct, ADJF17342, is available from ASTM.1.2 This practice is appropriate for any combination of squeeze tool, PE gas pipe and squeeze-off procedure, and is particularly appropriate for pre-1975 Polyethylene (PE) pipe, and for pipe sizes of 8 in. or above, because of a greater possibility of long-term damage.1.3 This practice is for use by squeeze-tool manufacturers, pipe manufacturers and gas utilities to qualify squeeze tools made in accordance with Specification F1563; and squeeze-off procedures in accordance with Guide F1041 with pipe manufactured in accordance with Specification D2513.1.4 Governing codes and project specifications should be consulted. Nothing in this practice should be construed as recommending practices or systems at variance with governing codes and project specifications.1.5 Where applicable in this guide, “pipe” shall mean “pipe and tubing.”1.6 Units—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.1.7 This standard does not purport to address all of the safety concerns, if any, associated with its use.

5.1 The major objective of this practice is to provide a common reference document for both applicants and certification authorities on the accepted practices for accomplishing package thermal qualification. Details and methods for accomplishing qualification are described in this document in more specific detail than available in the regulations. Methods that have been shown by experience to lead to successful qualification are emphasized. Possible problems and pitfalls that lead to unsatisfactory results are also described.5.2 The work described in this standard practice shall be done under a quality assurance program that is accepted by the regulatory authority that certifies the package for use. For packages certified in the United States, 10 CFR 71 Subpart H shall be used as the basis for the quality assurance (QA) program, while for international certification, ISO 9000 usually defines the appropriate program. The quality assurance program shall be in place and functioning prior to the initiation of any physical or analytical testing activities and prior to submittal of any information to the certifying authority.1.1 This practice defines detailed methods for thermal qualification of “Type B” radioactive materials packages under Title 10, Code of Federal Regulations, Part 71 (10CFR71) in the United States or, under International Atomic Energy Agency Regulation SSR-6. Under these regulations, packages transporting what are designated to be Type B quantities of radioactive material shall be demonstrated to be capable of withstanding a sequence of hypothetical accidents without significant release of contents.1.2 The unit system (SI metric or English) used for thermal qualification shall be agreed upon prior to submission of information to the certification authority. If SI units are to be standard, then use IEEE/ASTM SI-10. Additional units given in parentheses are for information purposes 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.1.4 This standard is used to measure and describe the response of materials, products, or assemblies to heat and flame under controlled conditions, but does not by itself incorporate all factors required for fire hazard or fire risk assessment of the materials, products, or assemblies under actual fire conditions.1.5 Fire testing is inherently hazardous. Adequate safeguards for personnel and property shall be employed in conducting these tests.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.

4.1 For conformance with the intent of the criteria listed in 2.2 and 2.3, coating qualification tests are founded on plant-specific test parameters that realistically reflect or bound the material and process variables that can reasonably be expected to influence qualification testing performance.4.2 This guide provides guidance for evaluating existing coating system qualification data for applicability to the nuclear plant desiring to use a coating system not previously used in the plant or to qualify an existing coating system.4.3 It is recognized that new-build plants, as well as small modular reactors currently under development, may have design features that differ from those of the operating plants that formed the basis for the existing test data. Therefore, careful review is required to assure that coating performance requirements critical to the new design are adequately addressed in the existing data or the need for additional coating testing is identified.1.1 The purpose of this guide is to identify evaluation variables that can be used to determine whether existing coating qualification test data (for example, design basis accident or DBA, chemical resistance, fire resistance, thermal conductivity, etc.) meet the respective nuclear power plant qualification requirements or whether requalification is required. Guidance on developing a coating qualification test plan/procedure to qualify a new coating is beyond the scope of this standard.1.2 This guide is intended for use in new construction and for refurbishing existing coating systems applied to concrete and metal substrates within containment.1.3 This guide is intended for the use by, or under the supervision of, a person knowledgeable in coating technology and coatings used in CSL I applications, such as a person meeting the requirements of Guide D7108 or equivalent.1.4 The values stated in inch-pound units are to be regarded as standard.

5.1 As with conventional radiography, radioscopic examination is broadly applicable to the many materials and object configurations which may be penetrated with X-rays or gamma rays. The high degree of variation in architecture and performance among radioscopic systems due to component selection, physical arrangement, and object variables makes it necessary to establish the performance that the selected radioscopic system is capable of achieving in specific applications. The manufacturer or integrator of the radioscopic system, as well as the user, require a common basis for determining the performance level of the radioscopic system.5.2 This practice does not purport to provide a method to measure the performance of individual radioscopic system components that are manufactured according to a variety of industry standards. This practice covers measurement of the combined performance of the radioscopic system elements when operated together as a functional radioscopic system.5.3 This practice addresses the performance of radioscopic systems in the static mode or dynamic mode, that can allow relative test-part motion between source, part, and detector, and may or may not have the ability to effect parameter changes during the radioscopic examination process. Users of radioscopy are cautioned that the dynamic aspects of radioscopy can have beneficial as well as detrimental effects upon system performance.5.4 Radioscopic system performance measured pursuant to this practice does not guarantee the level of performance which may be realized in actual operation but does provide a baseline against which periodic performance evaluations can be compared to ensure the system is operating within established limits. The effects of object-geometry and orientation-generated scattered radiation cannot be reliably predicted by a standardized examination. All radioscopic systems age and degrade in performance as a function of time. Maintenance and operator adjustments, if not correctly made, can adversely affect the performance of radioscopic systems; therefore, the system shall be re-qualified at periodic intervals (see Section 10).5.5 The performance of the radioscopic system operator in manual and semi-automatic radioscopic systems is not taken into account in this practice and can have a major effect upon radioscopic system performance. Operator qualifications and certification are an important aspect of system operation and are covered in a separate written procedure required by Practice E1255.1.1 This practice covers test and measurement details for measuring the performance of X-ray and gamma ray radioscopic systems. Radioscopy is a radiographic technique that can be used in (1) dynamic mode radioscopy to track motion or optimize radiographic parameters in real-time (25 to 30 frames per second), or both, near real-time (a few frames per second), or high speed (hundreds to thousands of frames per second) or (2) static mode radioscopy where there is no motion of the object during exposure as a filmless recording medium. This practice2 provides application details for radioscopic examination using penetrating radiation using an analog component such as an electro-optic device (for example, X-ray image intensifier (XRII) or analog camera, or both) or a Digital Detector Array (DDA) used in dynamic mode radioscopy. This practice is not to be used for static mode radioscopy using DDAs. If static radioscopy using a DDA (that is, DDA radiography) is being performed, use Practice E2698.1.1.1 This practice also may be used for Linear Detector Array (LDA) applications where an LDA uses relative perpendicular motion between the detector and component to build an image line by line.1.1.2 This practice may also be used for “flying spot” applications where a pencil beam of X-rays rasters over an object to build an image point by point.1.2 Basis of Application: 1.2.1 The requirements of this practice and Practice E1255 shall be used together. The requirements of Practice E1255 provide the minimum requirements for radioscopic examination of materials. This practice is intended as a means of initially qualifying and re-qualifying a radioscopic system for a specified application by determining its performance when operated in a static or dynamic mode. Re-qualification may require agreement between the cognizant engineering organization and the supplier, or specific direction from the cognizant engineering organization and should be addressed in the purchase order or the contract.1.2.2 System architecture including the means of radioscopic examination record archiving and the method for making the accept/reject decision are also unique system features and their effect upon system performance must be evaluated.1.2.3 This qualification procedure is intended to benchmark radioscopic system performance under selected operating conditions to provide a measure of system performance. Qualification shall not restrict operation of the radioscopic system at other radioscopic examination parameter settings, which may provide improved performance on actual examination objects. This practice neither approves nor disapproves the use of the qualified radioscopic system for the specified application. It is intended only as a standardized means of evaluating system performance.1.3 The general principles, as stated in this practice, apply broadly to transmitted-beam penetrating radiation radioscopy systems. Other radioscopic systems, such as those employing neutrons and Compton back-scattered X-ray imaging techniques, are not covered as they may involve equipment and application details unique to such systems.1.4 The user of this practice shall note that energies higher than 320 keV may require different methods than those described within this practice.1.5 This practice requires that a System Qualification Report be issued before using the system for production use.1.6 Units—The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.1.7 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.1.8 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.
