ISO/TC 67/SC 2/WG 15 - Testing procedures for mechanical connectors

ISO 21329:2004 specifies requirements and provides guidance for the testing of mechanical connectors for use in pipeline transportation systems for the petroleum and natural gas industries as defined in ISO 13623. The tests specified in ISO 21329:2004 are intended to form part of the design verification process for connectors. They provide objective evidence that connectors conform to a defined performance envelope. ISO 21329:2004 does not cover the use of design procedures as part of the qualification process for mechanical connectors, nor does it address fabrication and quality control. However, it can be used as input to a qualification procedure.Although its principles can be applied, ISO 21329:2004 does not address a) connectors that are designed to rotate in use, b) manifolds, c) topsides pipework or piping, d) flanges, e) connectors used in pipelines installed by reeling or J-tube pulls, f) factory acceptance testing, g) statistical bases for risk analysis.
