This standard BS EN 13555:2021 Flanges and their joints. Gasket parameters and test procedures relevant to the design rules for gasketed circular flange connections is classified in these ICS categories:

• 23.040.60 Flanges, couplings and joints
• 23.040.80 Seals for pipe and hose assemblies

This document specifies the gasket parameters required by EN 1591?1 and provides the test procedures for establishing the values of these parameters.

Gaskets which are wholly based upon elastomers, or based upon elastomers with only the inclusion of particulate fillers or particulate reinforcement, as opposed to gaskets combining elastomers, fillers and fibrous reinforcement, are beyond the scope of this document.
