1 Example of moisture retention after hydroextraction,
   and energy consumption

Describes methods of testing the effect on textiles processed on extracting machines (excluding washer extractors) in which water is removed mechanically from wet textile articles after washing. In the case of batch extraction machines, only machines are covered having a load capacity in excess of 7 kg of air-dry textile articles.
