3.1 Terms and definitions
For the purposes of this standard, the following terms and definitions apply.
3.1.1
Test cloths
They refer to the artificially-soiled cloth pieces, made of white cloths with specified types of stain through certain treatment procedures, used to determine the detergency of detergent. The types of test cloths are determined by the types of stains.
