Representatives of manufacturers and users of blow moulding machines, and of the employers liability insurance associations contributed to this standard. This standard contains specifications meeting the essential requirements set out in Annex
6、 I of the “Machinery Directive”, Directive 98/37/EC, (valid until 28 December 2009) and the “revised Machinery Directive“, Directive 2006/42/EC, which takes effect on 29 December 2009, and which apply to blow moulding machines that are either first placed on the market or commissioned within the EEA
7、. This standard serves to facilitate proof of compliance with the essential requirements of the directives. 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 r
8、equirements of the Machinery Directive (“presumption of conformity”). The European Standards referred to in clause 2 of this document have been published as the corresponding DIN EN or DIN EN ISO Standards with the same number. For the International Standard referred to there is no national document
