Test Background
The thermal cycle test of exterior wall insulation products can determine the pull-off performance of the exterior wall exterior insulation system. The fixation method of the system is mechanical fixation or a combination of mechanical fixation and adhesive fixation.
Zhongke Testing Reliability Experiment Center has the mechanical testing capabilities for various exterior wall and exterior insulation products, and provides professional thermal cycle mechanical testing services for exterior wall and exterior insulation products.
Scope of tests
1. Inorganic fibrous materials: glass wool and products, mineral wool and products.
2. Inorganic granular thermal insulation materials: expanded vermiculite and its products, expanded perlite and its products.
3. Inorganic porous thermal insulation materials: foam concrete, aerated concrete, diatomaceous earth, microporous calcium silicate, foam glass.
4. Organic insulation materials: foam plastics, plant fiber insulation panels, and window insulation films.
Test method
The foam block test is used to determine the pull-off resistance of external wall insulation systems. Pull-off resistance is calculated using the maximum tensile load.
1) Apply a tensile load perpendicular to the surface of the specimen in accordance with the method specified in ISO 29765. Unless otherwise specified or negotiated, load at a speed of (10±1) mm/min until the specimen fails.
2) Record the maximum tensile load. If the bonding layer between the sample and the foam block is damaged or the bonding layer between the foam block and the wood board is damaged, the test results will be invalid.
