Basic descriptions:
The effect of repeated application of pressure on the surface of a slab of polyurethane foam experienced in its normal life is evaluated by simulating these conditions in laboratory by applying and releasing a specified force for a specified number of times, after which the effect of such pounding on the physical characteristics such as hardness index, thickness, and cell structure are observed to evaluate the quality of foam slab.
The PROLIFIC Pounding Tester for polyurethane foam consists of a flat metallic platform for keeping the test specimen on, a circular indentor of specified shape and size which can be repeatedly lifted off and pressed against the foam slab, a motor operated arrangement to give movement to the indentor, and a counter to count the total number of poundings given to the test specimen.
The full force is applied to the specimen by the dead weight of the indentor. Suitable means have been provided to control the time for which the full force is applied. The time for load application shall not be more than 25% of the total duration of each cycle.
The horizontal platform is made from aluminium casting and has a number of holes drilled in it for the air to escape through.
The indentor is circular in shape and has a rounded edge to prevent damage to the test specimen during the test. It is moved along a vertical axis with the help of an eccentric and link arrangement. Movement to the indentor is given through two sets of V-belts and pulleys.
The height of the indentor can be adjusted to ensure that it is just lifted off the top of the test specimen at its highest point. Its movement can be adjusted between 20 and 50 mm. The movement is so adjusted that the indentor rests freely on the test specimen at the lower limit of its travel, thus exerting only the force due to its mass. Provision of over-travel of the rod on which that indentor it mounted ensures that the load does not exceed the specified value during the test.
A five digit pre-set type electronic counter with memory back-up is provided to count the number of poundings given to the test specimen and also to stop the motor after the desired number of poundings.
The equipment is fabricated over a rigid metallic frame and is finished in grey hammertone painting and bright chrome / zinc plating to give it a corrosion resistant finish.
