Carpet Dynamic Load Tester determines of thickness loss under dynamic loading. it performs an impact test on all types carpets and floor coverings To perform the test, subject the specimen to a cyclic-loading treatment in which an impact assembly. This two feet on its underside, repeatedly droops freely onto the specimen. The machine slowly transverse the specimen. The, The thickness of the specimen is measured before and after the procedure.
carpet Dynamic Load Tester is a fast, reliable and cost effective method of evaluating foundation bearing capacity. It can perform Dynamic Load Testing on driven piles, drilled shafts, auger-cast piles. Also, micropiles, helical piles, and other cast in place foundations. It is often possible to conduct several dynamic load tests in a single day.
In addition to bearing capacity, it also provides information on resistance distribution. That is the shaft resistance and end bearing. And evaluates the shape and integrity of the foundation element.
Load Testing for Carpets
The principle of the Dynamic Load Tester for Carpet is that a test specimen is subjected to a cyclic-loading treatment in which a weight-piece, with two steel feet on its underside, repeatedly drops freely onto the specimen. The specimen is slowly traversed so that vertical shearing forces produced by the edges of the feet act on the requisite area of the test specimen. The thickness of the specimen under test is measured before and after a test, to determine the thickness loss. The Dynamic Load Tester for Carpet is manufactured with a fully enclosed safety cabinet, to ensure no harm can come to the operator during a test. A Counter is positioned on the front of the machine to set the number of strokes in which a test is to operate at.
Test Sample Preparation
- At least 2 specimens should be tested from each sample selected.
- Cut each specimen 125mm x 125mm, with a side parallel to the warp (or to the machine production direction) and so that they do not contain the same warp or weft threads. All test specimens shall be cut at least 50mm from the selvedge.
- For specimens with a pile, brush the use-surface lightly first against, and then with the direction of pile lean using a ruler.
- Lay out the specimens flat, singly and with the use surface uppermost, in the chosen standard atmosphere for testing textiles, for at least 24 hours.
Carpet Load Testing Standard
The Standard AS/NZS 2111.2:1996 specifies a method for the determination of the thickness loss of textile floor coverings under dynamic loading. It is applicable to all types of textile floor coverings with a surface that is level in height and construction. It does not apply to other textile floor coverings unless the areas of different thickness or construction can be tested separately.
