This DN-07c checklist guides field crews through testing and purging medium pressure gas services up to 63 mm from the main to the service regulator or ECV. It covers equipment setup, 3 bar pressure testing with no permissible loss, leak detection using approved fluid, safe depressurization from the opposite end, and immediate recording of results. Purging and commissioning steps include purge hose and flame trap setup, maintaining communication between operatives, confirming 90 percent gas in air or time-based purging rates, and checking the service excess flow valve. Use this template to standardize procedures in alignment with SGN guidelines and improve safety and compliance.
