1.1This practice covers microwave (MW) examination of electrofusion joints made entirely of polyethylene for the purpose of joining polyethylene piping.

1.2The electrofusion joining process can be subject to a variety of flaws including, but not limited to, lack of fusion, particulate contamination, inclusions, and voids.

1.3The practice is intended to be used on joint thicknesses of 0.5 in. to 4 in. (12 mm to 100 mm) and diameters 4 in. (100 mm) and greater. Greater and lesser thicknesses and lesser diameters may be tested using this standard practice if the technique can be demonstrated to provide adequate detection on mockups of the same wall thickness and geometry.

1.4This practice can be applied to post assembly inspection of polyethylene electrofusion joints.

1.5This practice does not specify acceptance criteria.

1.6The 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.

1.7This 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.

1.8This 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.
