Designation:F129890(Reapproved 2018)An American National StandardStandard Specification forFlexible,Expansion-Type Ball Joints for MarineApplications1This standard is issued under the fixed designation F1298;the number immediately following the designation indicates the year oforiginal adoption or,in the case of revision,the year of last revision.A number in parentheses indicates the year of last reapproval.Asuperscript epsilon()indicates an editorial change since the last revision or reapproval.1.Scope1.1 This specification covers the design,manufacture,andtesting of ball joints utilized for accommodating thermalexpansion and contraction,or mechanical movement of apipeline carrying fluid.The ball joints are intended for use insystems operating above 0F(18C).1.2 The values stated in inch-pound units are to be regardedas standard.The values given in parentheses are mathematicalconversions to SI units that are provided for information onlyand are not considered standard.1.3 The following precautionary caveat pertains only to thetest methods portion,Section 7,of this specification:Thisstandard does not purport to address all of the safety concerns,if any,associated with its use.It is the responsibility of the userof this standard to establish appropriate safety,health,andenvironmental practices and determine the applicability ofregulatory limitations prior to use.1.4 This international standard was developed in accor-dance with internationally recognized principles on standard-ization established in the Decision on Principles for theDevelopment of International Standards,Guides and Recom-mendations issued by the World Trade Organization TechnicalBarriers to Trade(TBT)Committee.2.Referenced Documents2.1 ASTM
