Representatives of manufacturers and users of woodworking machines and chip and dust extraction systems, and of the employers liability insurance associations contributed to this standard. This standard contains specificati

This standard serves to facilitate proof of compliance with the essential requ
8、irements of that directive. Once this standard is cited 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”).

41、00:2010 for a description of A, B and C standards). NOTE Extraction systems as a whole are not intended to be installed in areas, where the presence of potentially explosive atmosphere needs to be taken into account. In relation to the previous version of the standard, the following main modificatio
42、ns have been made: The scope has been adjusted to meet the fields of application of the standard; The requirements for safety related controls have been modified for clarification; The requirements for electrical equipment and installations have been modified for clarification; The requirements for
43、fire and explosion protection have been modified for clarification; The requirements for noise protection have been modified for clarification; The requirements for protection against hazardous substances have been modified for clarification; The requirements for silos have been modified for clarifi
