1.2 This European Standard is not applicable to the following:
- experimental and testing machines, under development by the manufacturer;
- weighing devices;
- pressure dough dividers, without a feed hopper, using knives for the dividing process;
- lines with separate cutting or forming elements outside the housing;
- lifting and tilting machines ) or other separate feeding machines;
- additional hazards generated when the machine is used in a line or mechanically feed.
1.3 A noise test code is included in Annex A to assist manufacturers to measure noise levels for the purpose of the noise emission declaration.
1.4 This European Standard is not applicable to machines which are manufactured before its publication as EN.
