·Widely used in the evaluation of the appearance retention of carpets

·Can test with underlay underneath the carpet

·Provides a rapid method of test - completion within one working day

Specimens of carpet are fastened to a flexible backing sheet with double-sided adhesive tape. This assembly is fitted on the inside surface of the drum and can easily be removed at any stage for inspection of the specimens under test. If required, an underlay may be fitted beneath the carpet for direct comparison with normal use.

The drive to the drum incorporates a reversing mechanism to give more realistic pile disturbance, and the required number of revolutions may be preset on a revolution counter. The 3.8kg tumbler has six polyurethane stud feet.

The carpet specimens are treated for 2,000 revolutions, which takes approximately one hour. They are then taken out of the drum on their backing sheet and cleaned using an upright vacuum cleaner simulating practical usage. The specimens are replaced and the treatment repeated, normally six times, giving a total of 12,000 revolutions. After the final vacuum cleaning, the change in appearance is assessed against an appropriate set of ISO reference scales.
