【国外标准】 Standard Practice for Qualification of Polyethylene Saddle-Fused Joints

3.1 The tests described in this practice are intended to present a method of satisfying the requirements of DOT CFR Title 49, Parts 192.283 and 192.285.3.2 The sustained pressure test is intended to meet the burst test requirements of Part 192.283.3.3 The impact resistance test is intended to meet the force requirements of Part 192.283 as follows:3.3.1 “. . . For procedures intended for lateral pipe connections, subject a specimen joint made from pipe sections joined at right angles according to the (joining) procedure to a force on the lateral pipe until failure occurs in the specimen. If failure initiates outside the joint area, the (joining) procedure qualifies for use.”1.1 This practice describes test criteria suitable for qualification of polyethylene saddle-fused joints. These tests may be conducted by suppliers or users to qualify saddle-fused joints in accordance with the requirements found in the Department of Transportation (DOT) Code of Federal Regulations (CFR) Title 49, Part 192.283. At the discretion of the end user, these tests may also be conducted by users to qualify personnel making saddle fusion joints per DOT CFR 49, Part 192.285.1.2 The impact resistance test described is a nonstandard test. This is not the only test that may be used to qualify saddle fusion joints per DOT regulations.1.3 The values stated in inch-pound units are to be regarded as the standard. The values given in parentheses are mathematical conversion to SI units that are provided for information only and are not considered 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, health, and environmental practices and determine the applicability of regulatory limitations prior to use.1.5 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.
