After every hour of machine running time, remove theliner and clean the impeller by wiping with a cloth wetted in a solution of detergent and water. Allow the chamber to dry
Evaluation
Turn on the light of the viewing cabinet , Place the tested specimen and Original(Left Tested & Right Original) one onto the viewing cabinet ,
Using the viewing apparatus and option selected from and either suitable fabric or photographic standards subjectively rate
the appearance of the face (as indicated by the markings and after the respective tumbling times) of each specimen, using the following scale
5—no pilling
4—slight pilling
3—moderate pilling
2—severe pilling
1—very severe pilling
Average the ratings for the three specimens from each laboratory
