A dedicated pressurization fan is used to establish a stable pressure difference inside the test enclosure. The airflow required to compensate air leakage is measured to calculate air leakage rate and evaluate airtightness class. Airtightness and air leakage testing can be carried out complying with ASTM, ISO, BS EN/EN, GB/T and VDI standards.
On-site inspection for steel welds and structural components. Detect hidden defects by magnetic particle, penetrant, ultrasonic and visual testing following BS & EN standards.
Hydraulic pull-out test for anchors and fasteners on concrete or masonry substrates, to verify whether the fixing meets the designed load capacity.
