IGC 349

This standard covers electronic plumbing supply system integrity detection devices for commercial and residential applications and specifies requirements for materials, physical characteristics, performance testing and markings. Electronic plumbing supply system integrity detection devices covered by this standard can include the following features: (a) Monitoring of the hydraulic conditions (pressure, temperature, flow) within the main or branch circuit. (b) Automatic shut-off or electronic alarm notification and/or isolation of the supply piping when conditions are detected that indicate a leak or equipment malfunction. (c) Iterative analysis of high-resolution readings of system conditions to ensure contiguous integrity; and (d) Micro leak testing (drip detection). Note: Automatic water leak detection and control devices and Automatic water leak detection and shut-off devices that solely react to water contact to detect leaks are covered by IGC 115.
