Selection, application, and installation of standalone bursting discs Common engineering and design data ISO 4126-9
: High-velocity relief streams generate massive kinetic reaction forces. Structural engineers must design the discharge piping with robust supports to handle these dynamic physical loads without tearing loose from the safety device. Sourcing an Official ISO 4126-9 PDF

ISO 4126-2 details the requirements for bursting disc safety devices. These non-reclosing pressure relief devices consist of a thin membrane designed to rupture at a specified pressure, providing rapid, full-bore relief. The standard specifies requirements for their design, manufacture, inspection, testing, certification, marking, and packaging. The latest version is ISO 4126-2:2019, which corresponds to the 2018 edition of the international standard. A significant portion of the ISO 4126-2:2003 edition has also been superseded.
