Pressure equipment safety is a critical concern across numerous industries, from oil and gas to chemical processing and power generation. The International Organization for Standardization (ISO) has developed a comprehensive series of standards under ISO 4126, titled “Safety devices for protection against excessive pressure,” to address this vital field of engineering practice. This multi-part standard provides a globally recognized framework for selecting, applying, and installing safety devices that protect equipment from dangerous overpressure conditions.
