EN 12629-3:2002+A1:2010

1.1 This part of EN 12629, taken together with EN 12629-1:2000+A1, applies to machines for the manufacture of constructional products of calcium-silicate or concrete, where the mould(s) is(are) mounted on a turning or slide table. The motive power for compressing the mixture is effected either mechanically (Annexes A, B), or hydraulically (Annexes C and D). EN 12629-1:2000+A1 specifies general requirements applicable to machines for the manufacture of constructional products from concrete and calcium silicate. This document specifies the additional requirements to and/or the deviations from EN 12629-1:2000+A1 specific to the machines it covers. 1.2 This European Standard deals with all significant hazards pertinent to these machines, when they are used as intended and under conditions of misuse which are reasonably foreseeable by the manufacturer (see Clause 4). This European Standard specifies the appropriate technical measures to eliminate or reduce risks arising from the significant hazards. 1.3 This European Standard applies to the machines from the point at which the mixture enters the machine (see point 1 of annexes A, B, C, D) and the point where the pallets for concrete products are brought to the assembly (see point 8 at annexes C and D) until the point where the green products are removed from the machine to the curing system (see point 2 of annexes A, B, C, D). 1.4 This European Standard deals with the hazards listed in Clause 4 which can arise during the operation and maintenance, including the interfaces, of the slide and turntable machines, when carried out in accordance with the specifications given by the manufacturer or his authorised representative. This standard establishes safety requirements and/or methods of protection which apply to these machines. 1.5 This document is not applicable to block making machines, which are manufactured before the date of publication of this document by CEN.
