标准范围

本文件描述了用于输送流体的聚乙烯对接熔合（BF）接头的相控阵超声波检测（PAUT），包括管道到管道、管道到管件和管件到管件接头。本文件提供了一项测试，通过该测试，可以检测BF接头中是否存在缺陷，如空隙、夹杂物、未熔合、错位和颗粒污染。本文件仅适用于无超声波屏障的聚乙烯管道和配件。本文件还提供了程序鉴定要求和人员资格指南，这对本试验方法的应用至关重要。本文件还包括聚乙烯BF接头的设备、试验准备和性能、指示评估和报告。本文件不包括超声显示和验收标准的评估。注1:目前，实验室已有将PAUT用于壁厚在8 mm至100 mm之间的聚乙烯BF接头和/或对比试块的经验。最近，已经报道了PE80和PE100材料中高炉接头的现场经验。注2:循环试验表明，PAUT是增强BF接头完整性评估的可行方法。注3:冷聚变检测的PAUT技术已知可用。然而，要将该技术转化为ISO标准，还需要进一步的研究、验证和经验。本文件不提供有关冷熔合检测的任何信息。

This document describes the phased array ultrasonic testing (PAUT) of polyethylene butt fusion (BF) joints, including pipe-to-pipe, pipe-to-fitting and fitting-to-fitting joints, used for the conveyance of fluids. This document provides a test, whereby the presence of imperfections such as voids, inclusions, lack of fusions, misalignment and particulate contamination in the BF joints can be detected. The document is only applicable to polyethylene pipes and fittings without a barrier to ultrasonic waves.This document also provides requirements for procedure qualification and guidance for personnel qualifications, which are essential for the application of this test method.This document also covers the equipment, the preparation and performance of the test, the indication assessment and the reporting for polyethylene BF joints. The assessment of ultrasonic indications and acceptance criteria are not covered in this document.NOTE 1 At the present time, laboratory experiences exist on the use of PAUT for polyethylene BF joints and/or reference blocks of wall thickness between 8 mm to 100 mm^{[1] to [5]}. Recently, field experience on BF joints in PE80 and PE100 materials has been reported^[6].NOTE 2 Round robin testing has shown that PAUT is a viable method for enhancing the integrity assessment of BF joints^[7].NOTE 3 PAUT techniques for cold fusion detection are known to be available. However further research, verification and experience are needed to transfer the technique into an ISO Standard. This document does not provide any information regarding the detection of cold fusions.
