DIN EN 50724:2024-12

This document applies to ultrasonic gas leak detectors intended to provide an indication, alarm or other output function for the purpose of initiating automatic or manual protective action(s). This document specifies general requirements for design, testing and performance, and describes test methods that apply to UGLD. This document applies exclusively to gas detectors that use ultrasound to detect gas leaks. This document is also applicable when an equipment manufacturer makes any claims regarding any special features of construction or superior performance that exceed the minimum requirements of this document. This document prescribes that all such claims are verified, and that the test procedures are extended or supplemented, where necessary, to verify the claimed performance. The additional tests are agreed between the manufacturer and test laboratory and identified and described in the test report.
