Standard Test Method for Water Infiltration Resistance of Plastic Underground Conduit Joints Which Use Flexible Elastomeric Seals
SIGNIFICANCE AND USE 3.1 Underground electrical and communication conduit should be impervious to groundwater in order to prevent damage to conductors and utility vaults. The bladder test described in this test method may be used to qualify potential gasketed conduit systems by indicating whether the joint system will prevent water infiltration. 3.2 This test method can be used to qualify joints for plastic underground conduits using flexible elastomeric seals. However, it should not be assumed that a joint system that passes this test method will be able to seal under cases of misinstallation or abuse, or both. 3.3 This test method covers all of the following gasketed conduit types: encased burial (EB) excluding EB20, direct burial (DB), telecommunications, cable television, and Schedule 40 conduit and Schedule 80 conduit. Trade sizes covered are 2-in. nominal size and larger. (See UL 651; NEMA TC-2, TC-6, and TC 8; and Specification F512.) 3.4 This test method also covers fittings that are intended for use with the conduit types described in 3.3 and which use flexible elastomeric seals. SCOPE 1.1 This test method covers the determination of the water infiltration resistance of gasketed plastic underground conduit joints using a pressurized water bladder apparatus. 1.2 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. 1.3 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 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.
ASTM F1365-91(2023) - Standard Test Method for Water Infiltration Resistance of Plastic Underground Conduit Joints Which Use Flexible Elastomeric Seals provides a standardized methodology for evaluating the water infiltration resistance of joints in plastic underground conduits using flexible elastomeric seals. This test method ensures that underground conduit systems remain watertight, which is critical to protecting electrical conductors, communication cables, and utility vaults from groundwater intrusion.
This ASTM standard supports manufacturers, utility providers, and inspectors in ensuring that underground conduit systems meet necessary performance requirements, reducing the risk of service interruptions or equipment damage due to water ingress.
ASTM F1365-91(2023) is vital in the qualification and quality assurance of plastic underground conduit systems. Its key practical applications include:
