By correctly identifying and using ISO 4126-9, you ensure that your pressure equipment is protected by the most current, globally recognized safety practices.
The ISO 4126 standard is divided into multiple components under the general title Safety devices for protection against excessive pressure . While other parts dictate how safety hardware is built and tested in a factory, Part 9 bridges the gap between manufacturers and field engineers. It focuses entirely on how these safety devices are integrated into real-world piping systems. Standard Part Technical Focus Area Safety valves (design and production) ISO 4126-2 Bursting disc safety devices ISO 4126-3 Safety valves and bursting discs used in combination ISO 4126-4 Pilot-operated safety valves ISO 4126-5 Controlled safety pressure relief systems (CSPRS) ISO 4126-6 While other parts dictate how safety hardware is

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 A significant portion of the ISO 4126-2:2003 edition has also been superseded. These non-reclosing pressure relief devices consist of a
