BS EN ISO 4126-10:2024 - TC

This standard BS EN ISO 4126-10:2024 - TC Tracked Changes. Safety devices for protection against excessive pressure is classified in these ICS categories:

• 23.060.40 Pressure regulators
• 13.240 Protection against excessive pressure

This document specifies the sizing of safety valves and bursting discs for gas/liquid two-phase flow in pressurized systems such as reactors, storage tanks, columns, heat exchangers, piping systems or transportation tanks/containers, see Figure 2. The possible fluid states at the safety device inlet that can result in two-phase flow are given in Table 1. NOTE          The pressures used in this document are absolute pressures, not gauge pressures.
