Presumed compliance with essential requirements on the basis of harmonised standards

According to the Directive, art. 7 (2), machinery manufactured in conformity with a harmonized standard, the references to which have been published in the Official Journal of the European Union, shall be presumed to comply with the essential health and safety requirements covered by such a harmonised standard. This allows translating the general requirements of the Directive into more detailed technical requirements and manufacture machinery that meets safety requirements. There are 3 types of safety and health standards in terms of designing and construction of machinery and safety components:

 

Types of harmonised standards

Standards type A: (basic) – define the basic notions in machinery safety, set out general issues and principles for designing (construction) concerning all machinery types included in the Directive;

Standards type B: (problem) – refer to specific safety issues, common for several machinery types or safety components used in them. There are two subcategories: B1 – particular aspects of safety, e.g., safety distances, noise, temperatures, etc.) and B2 – safety components (np. two-hand control devices, blocking devices, pressure- or electric-sensitive devices, etc.);

Standards type C: (detailed) – set out detailed safety requirements related to particular types or groups of machinery;

 

Conformity assessment in various cases

Article 12 of Directive 2006/42/EC sets out procedures for assessing conformity with Essentials requirements, whose positive result is a confirmation of fulfilled regulations of the Directive. The responsibility for applying one of approved procedures is with the manufacturer or his authorized representative. Depending on the category the machinery belongs to, according to Annex IV and the available harmonised standards there are three cases of application of procedures of conformity assessment. In specified cases the directive provides for obligatory participation of a notified body in the process, consisting in EC type-examination or supervising the procedures of full quality assurance. In cases 1 and 2a the involvement of a notified body is not obligatory but possible with a voluntary decision of the entity placing the machinery on the market. In cases 2b and 3a it is necessary to engage a notified body for EC type examination of machinery, whose positive result should be confirmed with an appropriate certificate. In cases 2c and 3b a notified body assesses, approves and monitors the system of full quality assurance (including the stages of designing and manufacturing the machinery), in the manufacturing process.

Central Institute for Labour Protection – National Research Institute is a notified body no. 1437 under Directive 2006/42/EC and upon a contract from the manufacturer or his authorised representative performs EC type examination or assesses, approves and monitors the system of full quality assurance in manufacturing machinery.
