Representatives of manufacturers and users of pendulum cross-cut sawing machines, and of the employers liability insurance associations contributed to this standard. This standard contains specifications meeting the essential requirements set ou

7、t in Annex I of the “Machinery Directive”, Directive 2006/42/EC, and which apply to machines that are either first placed on the market or commissioned within the EEA. This standard serves to facilitate proof of compliance with the essential requirements of that directive. Once this standard is cite

8、d in the Official Journal of the European Union, it is deemed a “harmonized” standard and thus, a manufacturer applying this standard may assume compliance with the requirements of the Machinery Directive (“presumption of conformity”). The European Standards referred to in Clause 2 and in the Biblio
