Pneumatic testing with compressed air or an inert gas (such as nitrogen) is tightly restricted due to high stored kinetic energy, which poses significant safety risks if a rupture occurs. TR/6 allows pneumatic testing only under specific conditions—such as when water entry is prohibited by process requirements or during sub-zero winter conditions where freezing is a threat. It mandates strict preliminary low-pressure leak checks prior to ramping up to full proof pressures.

Mandatory pre-test checklists evaluating joint security, structural support anchor stability, and temporary blanking cap ratings. Sourcing and Accessing the Document
Standard testing practices outlined in TR6 and related industry specifications (like those from ) include: Test Pressure Levels LTHW & CHW Systems : Typically tested at no less than 1.5 times the maximum working pressure Domestic Water 1.5 times the closed head pressure of the booster set. High-Pressure Scenarios : If working pressure exceeds 10 bar, a test of at least 2 bar above closed head pressure for a duration of 2 hours may be permitted.
