Abstract
This European Standard deals with the technical requirements to minimise the hazards listed in clause 4 and annex A. These hazards can arise during the operation and maintenance of equipment to store bulk materials in silos, bunkers, bins and hoppers and their built-in inlet and outlet devices when carried out in accordance with the specifications given by the manufacturer or his authorised representative. This standard deals with safety related technical verification during commissioning.
The following parts are dealt with in this standard (see Figure 1):
NOTE Silos are made of different materials e.g. concrete, steel, aluminium, spun rayon, wood.
Safety requirements and/or measures in this standard apply to equipment used in all environments. However, additional risk assessment and safety measures need to be considered in severe conditions, e.g. low or high temperatures out of the range covered by EN 60204-1, corrosive environments, strong magnetic fields, radioactive conditions and bulk materials to be stored included their flow the nature of which could lead to a dangerous situation.
This standard does not cover requirements for:
- movable, non permanent storage equipment such as road vehicles, rail wagons, containers for bulk materials, ships and barges;
- blow tanks and pressure vessels as used in pneumatic conveying systems;
- stockpiles and flat storage;
- storage equipment for non bulk materials (liquid, gas, slurries, sludge, silage);
- dismantling and transport of storage equipments;
- procedure for entering the silo and behaviour of persons inside the silo;
- storage equipments for underground mining;
- "noise."
This European Standard deals with the technical requirements for electromagnetic compatibility (EMC).
