A controlled test performed to verify the integrity, strength and leak-tightness of pressure-retaining equipment.
A Pressure Test is a controlled procedure used to verify the structural integrity, pressure-retaining capability and leak-tightness of pressure vessels, piping or other pressure equipment by applying a specified test pressure under controlled conditions. Pressure testing is commonly performed during fabrication, installation, repair or recertification to demonstrate compliance with applicable engineering codes and specifications.
Pressure Tests verify that pressure-retaining equipment can safely withstand specified test conditions before being placed into or returned to service.
Pressure Tests may be hydrostatic or pneumatic depending on equipment design, service requirements, applicable codes and safety considerations.
A Pressure Test verifies the integrity of pressure equipment under controlled test conditions, whereas in-service inspection evaluates equipment condition during its operational life.
