ISO/TC 23/SC 7/WG 11 - Pick-up balers and bale wrappers - Safety requirements

ISO 4254-14:2016 intended to be used together with ISO 4254‑1, specifies the safety requirements and their verification for the design and construction of mounted, semi-mounted, trailed, and stationary bale wrapper for bales of agricultural harvesting products including wrappers which are combined or integrated with pick-up balers. It describes methods for the elimination or reduction of hazards arising from the intended use and reasonably foreseeable misuse of these machines by one person (the operator) in the course of normal operation and service. In addition, it specifies the type of information on safe working practices to be provided by the manufacturer. NOTE 1 Requirements for self-propelled bale wrappers may be added during the next revision of this part of ISO 4254. NOTE 2 Examples of these machines are given in Annex A. NOTE 3 Requirements for pick-up balers are specified in ISO 4254‑11. When requirements of this part of ISO 4254 are different from those which are stated in ISO 4254‑1, the requirements of this part of ISO 4254 take precedence over the requirements of ISO 4254‑1 for machines that have been designed and built according to the requirements of this part of ISO 4254. This part of ISO 4254, taken together with ISO 4254‑1, deals with all the significant hazards (as listed in Table 1), hazardous situations, and events relevant to mounted, semi-mounted, and trailed bale wrappers including wrappers which are combined with pick-up balers when they are used as intended and under the conditions of misuse that are reasonably foreseeable by the manufacturer (see Clause 4). ISO 4254-14:2016 is not applicable to the following: - non-mobile fixed bale wrappers; - tube/inline wrappers; - wrapping process that concerns only the circumferential part of the bale and that occurs in the bale chamber; - the integrity of safety related parts of control systems with regard to the specification of performance levels; - environmental hazards (except noise), road safety, and hazards related to moving parts for power transmission; - hazards related to maintenance or repairs carried out by professional service personnel. NOTE 4 Specific requirements related to road traffic regulations are not taken into account in this part of ISO 4254. ISO 4254-14:2016 is not applicable to machines manufactured before the date of its publication.
