| Published By | Publication Date | Number of Pages |
| BSI | 2018 | 68 |
This European Standard is applicable to tumble dryers intended to be used by trained users e.g. in hotels, hospitals, factories, in light industry and on farms. It covers tumble dryers declared for commercial use in public areas and operated by lay persons e.g. in launderettes, apartment houses and communal laundry rooms. This European Standard covers tumble dryers which use electricity, gas or steam as a heating source. The object is to state and define the principal performance characteristics of tumble dryers for commercial use of interest to users and to describe standard methods for measuring these characteristics. NOTE It does not apply to transfer tumble dryers or tumble dryers only possible to operate with automatic loading and unloading.
