ISO 28139:2009(E) iv © ISO 2009 – All rights reserved Foreword ISO (the International Organization for Standardization) is a worldwide federation of national standards bodies (ISO member bodies). The work of preparing International Standards is normally carried out through ISO technical committees. Each member body interested in a subject for which a technical committee has been established has the right to be represented on that committee. International organizations, governmental and non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization. International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2. The main task of technical committees is to prepare International Standards. Draft International Standards adopted by the technical committees are circulated to the member bodies for voting. Publication as an International Standard requires approval by at least 75 % of the member bodies casting a vote. Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. ISO shall not be held responsible for identifying any or all such patent rights. ISO 28139 was prepared by the European Committee for Standardization (CEN) Technical Committee CEN/TC 144, Tractors and machinery for agriculture and forestry, in collaboration with Technical Committee ISO/TC 23, Tractors and machinery for agriculture and forestry, Subcommittee SC 6, Equipment for crop protection, in accordance with the Agreement on technical cooperation between ISO and CEN (Vienna Agreement).

ISO 28139:2009(E) © ISO 2009 – All rights reserved v Introduction This document is a type-C standard as stated in ISO 12100. The machinery concerned and the extent to which hazards, hazardous situations or hazardous events are covered are indicated in the Scope of this document. When requirements of this type-C standard are different from those which are stated in type-A or B standards, the requirements of this type-C standard 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.
INTERNATIONAL STANDARD ISO 28139:2009(E) © ISO 2009 – All rights reserved 1 Agricultural and forestry machinery — Knapsack combustion-engine-driven mistblowers — Safety requirements IMPORTANT — The electronic file of this document contains colours which are considered to be useful for the correct understanding of the document. Users should therefore consider printing this document using a colour printer. 1 Scope This International Standard specifies safety requirements and their verification for the design and construction of knapsack mistblowers incorporating a combustion engine where the air flow is generated by a fan. It describes methods for the elimination or reduction of hazards arising from their use. In addition, it specifies the type of information on safe working practices to be provided by the manufacturer. It does not, however, give any technical requirement for reducing noise or vibration hazards. Indeed, the different means available to reduce these hazards are a matter for the technical aids to which the manufacturer may resort, through specialized books or specified bodies. This International Standard deals with all significant hazards, hazardous situations and events, excepting those arising from ⎯ electromagnetic compatibility, ⎯ static electricity, ⎯ explosion or fire from chemicals for spraying, ⎯ insufficient structural integrity, and ⎯ noise and vibration. It is applicable to knapsack combustion-engine-driven mistblowers when they are used as intended and under the conditions foreseen by the manufacturer (see Clause 4). It is not applicable to knapsack combustion-engine-driven mistblowers manufactured before the date of its publication. SIST EN ISO 28139:2010
