本标准规定了超声检测人员、相控阵超声检测仪器、相控阵超声探头、相控阵超声扫查装置、试块、耦合剂、扫查方式扫描类型和显示方式、聚焦法则的一般要求。本条款依据了常规相控阵超声相关标准内的条款，并考虑了针对非金属管道接头检测的特殊要求，尤其对于测试用相控阵探头做了规定，提出可以加装辅助声束偏转的楔块（包括液体楔块、低衰减胶体楔块或聚苯乙烯等低声束固体楔块）来进行检测。条款还提出了标准试块、对比试块和模拟试块的规定，对试块材料、曲面检测以及耦合剂的选择做了规定。

规定了超声检测人员、检测工艺文件、检测设备、相控阵探头、试块、扫描装置、耦合剂的一般要求。本条款依据了常规相控阵超声相关标准内的条款，并考虑了针对非金属管道接头检测的特殊要求，尤其对于测试用相控阵探头做了细致规定：聚焦探头其会聚区范围应能满足检测聚乙烯管道电熔接头内缺陷深度的要求且与被检测面有良好的配合。考虑到非金属管道对超声的衰减影响严重，相控阵探头应由多个晶片（阵元）（不少于32个）组成阵列，以保证探头具有足够的能量穿透待测管道。要求还对探头晶片之间的灵敏度差异提出了具体要求。

1.1 This specification covers poly(vinyl chloride) (PVC) pipe made in Schedule 40, 80, and 120 sizes and pressure-rated for water (see Appendix X1). Included are criteria for classifying PVC plastic pipe materials and PVC plastic pipe, a system of nomenclature for PVC plastic pipe, and requirements and test methods for materials, workmanship, dimensions, sustained pressure, burst pressure, flattening, and extrusion quality. Methods of marking are also given. 1.2 The products covered by this specification are intended for use with the distribution of pressurized liquids only, which are chemically compatible with the piping materials. Due to inherent hazards associated with testing components and systems with compressed air or other compressed gases some manufacturers do not allow pneumatic testing of their products. Consult with specific product/component manufacturers for their specific testing procedures prior to pneumatic testing. NOTE 1—Pressurized (compressed) air or other compressed gases contain large amounts of stored energy which present serious saftey hazards should a system fail for any reason. NOTE 2—This standard specifies dimensional, performance and test requirements for plumbing and fluid handling applications only. It does not include provisions for the use of these products for venting of combustion gases. UL 1738 is a standard that does include specific testing and marking requirements for flue gas venting products, including PVC. 1.3 The text of this specification 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 specification. 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 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.A specific precautionary statement is given in Note 9. NOTE 3—CPVC plastic pipes, Schedules 40 and 80, which were formerly included in this specification, are now covered by Specification F441/F441M. NOTE 4—The sustained and burst pressure test requirements, and the pressure ratings in the Appendix X1, are calculated from stress values obtained from tests made on pipe 4 in. (100 mm) and smaller. However, tests conducted on pipe as large as 24 in. (600 mm) diameter have shown these stress values to be valid for larger diameter PVC pipe. NOTE 5—PVC pipe made to this specification is often belled for use as line pipe. For details of the solvent cement bell, see Specification D2672 and for details of belled elastomeric joints, see Specifications D3139 and D3212. 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.

1.1 This specification covers requirements and test methods for materials, dimensions, workmanship, flattening resistance, impact resistance, pipe stiffness, extrusion quality, and a form of marking for folded poly(vinyl chloride) (PVC) pipe for existing sewer and conduit rehabilitation. 1.2 Folded PVC pipe produced to this specification is for use in non-pressure sewer and conduit rehabilitation where the folded PVC pipe is inserted into and then expanded to conform to the wall of the original conduit forming a new pipe-withina-pipe. NOTE 1—For installation procedures and engineering design considerations refer to Practice F1947. 1.3 This specification includes folded PVC pipe made only from materials specified in Section 6. This specification does not include folded pipe manufactured from reprocessed, recycled, or reclaimed PVC. 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 statement pertains to the test method portion only, Section 11, 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. 1.6 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.
