What is BS EN 12609 about?
BS EN 12609 specifies the safety requirements for truck mixers and also covers the interface between the mixing unit and the truck or trailer (but not the truck or trailer itself).
BS EN 12609 deals with all significant hazards, hazardous situations and events relevant to truck mixers when they are used as intended and under the conditions of misuse which are reasonably foreseeable by the manufacturer (see Annex D).
BS EN 12609 specifies the appropriate technical measures to eliminate or reduce risks arising from the significant hazards during transportation, assembly, dismantling, disabling, scrapping, operation and maintenance of the truck mixer.
NOTE 1: Truck or trailer constructed primarily for the carriage of goods as classified according to the directive 2007/46/EC, category N3 or O4.
BS EN 12609 does not cover:
- Additional equipment (conveyor belt, mortar pump, concrete pump, concrete-placing boom)
- Requirements for operation in tunnels
- Truck or self-propelled mixers equipped with self-loading systems
- Front-discharge mixers
- Mixing units with articulated steering
- Truck mixer drum cleaning systems
- Energy source(s).
BS EN 12609 does not deal with carrier vehicles, e.g., trucks, tractors, construction machinery and mobile industrial handling equipment or other self-propelled vehicles.
BS EN 12609 does not include requirements that are covered in directives related to the construction of vehicles or national road regulations.
NOTE 2: The use in public road traffic is governed by national regulations.
BS EN 12609 is not applicable to machines that are manufactured before the date of publication of this document by CEN.

Why should you use BS EN 12609?
BS EN 12609 is a type-C standard as stated in EN ISO 12100 which deals with detailed safety requirements for a particular machine or group of machines. BS EN 12609 helps you to take precedence over the requirements of the other standards for machines that have been designed and built according to the requirements of this type-C standard.
BS EN 12609 provides technical measures which help you eliminate or reduce risks arising from the significant hazards during the lifetime of the machinery as described in EN ISO 12100:2010.
BS EN 12609 helps you with noise-test code for noise measurement which ensures reproducibility of the determination of the noise-emission characteristics within specified limits determined by the grade of accuracy of the basic noise measurement method used
