The following criteria must be implemented:
• | Leak testing must meet the requirements of SANS 1737. |
• | Leak test shall adhere to a series of physical performance and basic specifications. |
• | A benchmark must be set stipulating minimum pressure measurements and standard evacuation times. |
Leak test parameters:
• | For shallow mining (i.e. mines less than 500m in depth, e.g. coal mines) |
Test pressure = -70mbar or -7000Pa or -7kpa or -0.07bar
• | For deep mining (i.e. mines deeper than 500m in depth, e.g. gold and some platinum mines) |
Test pressure = -200mbar or -20000Pa or -20kpa or -0.2bar
Leak test intervals should be indicated, based on risk assessment, but should be performed at least bi-annually.
