This paper, Part 2 of the study, presents a process of development of a device for accelerating stains on polymeric floor finishing materials. This device is designed to instantly produce stains which are similar to those on actually exposed floors. The procedure of the development of the device was as follows : 1. Following the findings through observation of the actual state of stains, which were reported in Part 1, the degree of perceived stains was defined as a perceived change from the virgin state. Thus the degree of perceived stains can be judged by compairing the stained material in question with one in the virgin state. 2. An availability of several different sensory test was examined and a paired-comparison-method and a method of rank-order were found to be suitable for judging the degree of stains. Thus two psychological scales for measuring the degree of perceived stains were created. 3. The change of optical conditions (average color differences) of stained materials was measured and it was found to be significantly correlated with the degree of perceived stains on the psychological scales. 4. A specification of the accelerating device for stains was decided on the basis of the similarity of the optical conditions of the products to the actually exposed materials.
