1.1 This European Standard applies to hydraulic machines for the manufacture of bricks, blocks and elements of calcium-silicate (as illustrated in annexes A and B). NOTE Calcium-silicate can be replaced by concrete. 1.2 This European Standard deals with all significant hazards pertinent to these machines, when used as intended under the conditions foreseen by the manufacturer (see clause 4). This European Standard specifies the appropriate technical measures to eliminate or reduce risk arising from significant hazards. 1.3 This European Standard applies to the machines from the point at which the mixture enters the machine (see point 1 at annex A, B) until the point where the green products are removed from the machine to the curing system (see point 2 of annex A, B). 1.4 This European standard does not cover those requirements for reducing hazards from mechanical, electrical, pneumatic, hydraulic or other equipment or machinery that are dealt with in standards for their common use (Type A, B1 and B2 standards). 1.5 This European Standard deals with the hazards other than noise hazards 1) listed in clause 4 which can arise during the operation and maintenance, including the interfaces, of machines for the manufacture of constructional products from calcium-silicate, when carried out in accordance with the specifications given by the manufacturer or his authorised representative. NOTE 1 Amendment is under preparation to deal with noise, in particular for measures to reduce noise at source and a noise test code including noise declaration. NOTE 2 Interfaces between the machines for the manufacture of constructional products from calcium-silicate and others of the installation are dealt with in 7.2 of EN 12629-1:2000. This standard establishes safety requirements and/or methods of protection which apply to these machines. At this time, noise hazard and vibration hazard are considered as not significant for those machines.
