6、tee AGE/32 and is the English language version of EN 708:1996 Agricultural machinery Soil working machines with powered tools Safety, including amendment A1:2000, published by the European Committee for Standardization (CEN). The United Kingdom as a member of CEN is obliged to publish EN 708:1996 as
7、 a British Standard. However attention is drawn to the fact that during the development of this European Standard the United Kingdom has consistently voted against its approval as an EN. The UK believes that the standard is deficient in certain safety requirements compared with the state of the art
8、for these machines in the UK and that in consequence the standard fails to meet some of the essential requirements of the EC Machinery Safety Directive, 89/392 and amendments, which it claims to meet. Although CEN approved EN 708:1996 for publication in its present form there is no reference to it i
9、n the Official Journal of the European Communities. It should therefore be noted that until the standard is listed in the Official Journal, compliance with it will not give automatic presumption of compliance either with the relevant essential requirements of the EC Machinery Directive or the UK Sup
10、ply of Machinery (Safety) Regulations 1992 as amended in 1994. As part of BSI s duty of care we draw attention to users of BS EN 708:1997 of our concern that the standard contains inadequate requirements for protection of personnel against unintentional contact with the powered tools specifically wi
11、th regard to clause 4.2.2 and the absence of a strength requirement for barriers and lateral guards. BSI will assume no liability whatsoever for any failure on the part of any user of this standard to consider these aspects. Cross-references The British Standards which implement international or Eur

A British Standard does not purport to include all the
13、necessary provisions of a contract. Users of British Standards are responsible for their correct application. Compliance with a British Standard does not of itself confer immunity from legal obligations. Summary of pages This document comprises a front cover, an inside front cover, pages i and ii, t

EN 708:1996 BSI 01-20013 Introduction The extent to which hazards are covered is indicated in the scope of this standard. These hazards are specific to soil working machin
32、es with powered tools. The hazards that are common to all agricultural machines (self-propelled, mounted, semi-mounted and trailed) will be dealt with in a standard currently in preparation (EN 1553). 1 Scope This standard specifies safety requirements and their verification for the design and const
33、ruction of soil working machines, mounted or trailed, with tools powered by the engine of the tractor or by an auxiliary motor. It is applicable regardless of the type of movement of the tools. This standard is not applicable to: spading machines; pedestrian controlled soil working machines; machine
34、s where the tools are driven by movement of the machine over the ground; machines fitted with a retractable device, making them capable of working between two successive plants in the same row. It describes methods for elimination or reduction of risks which need specific requirements for soil worki
35、ng machines with powered tools. It does not deal with general hazards, particularly general hazards related to the mobility. These aspects will be dealt with in a standard currently in preparation (EN 1553). In addition, it specifies the type of information on safe working practices to be provided b
36、y the manufacturer. The list of significant hazards dealt with in this standard is given in Annex A. Annex A also indicates the hazards which have not been dealt with. NOTEThe measures for safeguarding the PTO shaft are dealt with in the “ Common requirements” standard being prepared by CEN/TC 144.
37、Environmental aspects have not been considered in this standard. This standard applies primarily to machines which are manufactured after the date of issue of the standard. 2 Normative references This European Standard incorporates by dated or undated reference, provisions from other publications. T
38、hese normative references are cited at the appropriate places in the text and the publications are listed hereafter. For dated references, subsequent amendments to or revisions of any of these publications apply to this European Standard only when incorporated in it by amendment or revision. For und

41、initions For the purposes of this standard, the following definition applies: soil working machine with powered tools machine with powered tools designed for modifying soil structure or profile and/or for incorporating plants, crop residues or animal manure during tillage NOTENon-restrictive example
42、s of such machines are given in Annex B. ? EN 708:1996 4 BSI 01-2001 4 Safety requirements and/or measures 4.1 General Machines shall comply as appropriate with EN 292 for hazards which are not dealt with and especially with Annex A of EN 292-2:1991/A1:1995 when EN 292 does not give precise requirem
43、ents. Unless otherwise specified in this standard, the machine shall comply with the requirements of EN 1553:1999 and with Tables 1, 3, 4 and 6 of EN 294:1992. 4.2 Protection against hazards related to moving parts 4.2.1 Protection against hazards related to moving power transmission parts To ensure
44、 protection against hazards related to accessible moving power transmission parts, the machine shall be fitted with fixed guards (according to 3.22.1 of EN 292-1:1991). When frequent access is foreseen, the machine shall be fitted with guards needing a tool for their opening. These guards shall rema
45、in attached to the machine when opened (for example by means of hinges) and automatically lock in closed position without the use of a tool. If this type of guard is not used, the machine shall be fitted with: interlocking movable guards (according to 3.22.4 of EN 292-1:1991); or movable guards fitt
46、ed with a device which prevents their opening so long as the parts are moving. 4.2.2 Protection against unintentional contact with the tools 4.2.2.1 Machines shall be designed or guarded in such a way that any unintentional contact with the powered tools at the front, at the rear, at the sides and o
47、n the top is avoided. At the front, at the sides and at the rear of the accessible zone, a barrier shall be placed at a maximum height of 400 mm from the lower tools path and at a minimum horizontal distance a of 200 mm from the tools path (see Figure 1 and Figure 2). On the top, the area between th
48、e barriers shall be completely guarded: the area which covers the tools at least up to the outer points of their path shall be guarded by an imperforate guard; the area between the barriers and the edge of the top guard shall be guarded in such a way that it shall not be possible to pass a 61mm sphe
49、rical test gauge through this area. The guarding may be achieved by a guard or any part of the machine or a combination of both. The test gauge shall be of mild steel and shall be applied by hand. The machine and its guards shall be set in the most unfavourable positions. The top guard, the barriers and the parts of the machine ensuring the guarding shall withstand a vertical downwards load of 1 200 N. The barriers shall additionally withstand t
