Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. CEN [and/or CENELEC] shall not be held responsible for identifying any or all such patent rights.

EN 15695, Agricultural tractors and self-propelled sprayers – Protection of the operator (driver) against hazardous substances, consists of the following parts: Part 1: Cab classification, requirements and test procedures Part 2: Filters, requirements and test procedures According to the CEN/CENELEC Internal Regulations, the national standards organizations of the following countries are bound to implement this European Standard: Austria, Belgium, Bulgaria, Cyprus, Czech Republic, Denmark, Estonia, Finland, France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Latvia, Lithuania, Luxembourg, Malta, Netherlands, Norway, Poland, Portugal, Romania, Slovakia, Slovenia, Spain, Sweden, Switzerland and the United Kingdom.

EN 15695-1:2009 (E) 5 Introduction This document is a type C standard as stated in EN ISO 12100. The machinery concerned and the extent to which hazards, hazardous situations and hazardous events are covered are indicated in the scope of this European Standard. When provisions of this type C standard are different from those which are stated in type A or B standards, the provisions of this type C standard take precedence over the provisions of the other standards, for machines that have been designed and built according to the provisions of this type C standard. When operating self-propelled sprayers or tractors the operator can be exposed to hazardous substances such as dust, aerosols or vapours (for example during the application of plant protection products or fertilisers). Cabs of agricultural tractors and self-propelled sprayers providing protection against these substances may respectively be used to reduce operator exposure to air-borne contaminants generated during farming operations.
With regard to the application of plant protection products (PPP) the operator can be exposed to risks:
before the actual spraying operation (e.g. handling of PPP cans/packages, spray tank filling, sprayer adjustment); during the spraying operation (e.g. on the tractor or self-propelled sprayer with/without cab, when working at the sprayer when adjusting the sprayer in the field, removing nozzle blockages, etc.); after the spraying operation (e.g. when removing residues, sprayer cleaning, service and maintenance operations). Protective measures (personal protective equipment (PPE)) are specified on labels today, for example: dermal exposure: gloves, overall, apron, headdress (with face protection), protective goggles; respiratory exposure: filtering half masks. The objective of this European Standard is to improve the operator protection by using the protective function of the cab of self-propelled sprayers and tractors in case of mounted or trailed sprayers. For this purpose this European Standard specifies cab categories, performance requirements, test procedures and the operator information to be provided, in particular with regard to installation, use and maintenance operations.
