scope:

NEN-EN 454 specifies safety and hygiene requirements for the design and manufacture of fixed bowl planetary mixers with a tool having a planetary movement. The capacity of the bowl is greater than or equal to 5 l and less than or equal to 200 l. These machines are used to process various ingredients e.g. cocoa, flour, sugar, oils and fat, minced meat, eggs, and other ingredients, in the catering, bakery, pizza, pastry and confectionary industry. These machines are sometimes used in other industries (e.g. pharmaceutical industry, chemical industry, printing, etc.), but hazards related to these uses are not dealt with in this standard. Processing is carried out in cycles of variable duration. It can be either manually or automatically-controlled, in individual cycles or on a cycle repeat basis, etc. Manual operations are sometimes necessary to add ingredients without stopping the beater. On machines fitted with a bowl lifting and lowering device or with a device for moving the bowl/head/beater vertically the working position is that when the beater is nearest to the bottom of the bowl. This European Standard deals with all significant hazards, hazardous situations and events relevant to planetary mixers, when they are used as intended and under the conditions of misuse which are reasonably foreseeable by the manufacturer. It deals with the hazards due to the use, the maintenance and the cleaning (see Clause 4).
