Specifications for industrial laundry machines. Definitions and testing of capacity and consumption characteristics – Washer-extractors
| Published By | Publication Date | Number of Pages |
| BSI | 2019 | 86 |
This document defines the characteristics of washer-extractors and gives the usual test methods for these characteristics with regard to machine capacity, power consumption and productivity. It is applicable for use as a reference in the drafting of purchasing orders for washer-extractors whose net usable cage volume is 400 dm3 (litres) respectively 40 kg and above. In addition, it is recommended for determination of energy consumption and productivity according to Directive 2009/125 EC. Furthermore, the document describes standard methods for measuring principal performance characteristics of washer-extractors. It does not cover safety requirements (see EN ISO 10472-2).
