BS EN 12786:2013

What is BS EN 12786 - Drafting of the vibration clauses for type-C standards about? 

BS EN 12786 is a safety standard that aims to provide best industry guidance on the drafting of vibration clauses such that hazards while operating machinery can be minimized.

BS EN 12786 gives guidance for the writers of harmonized type-C machinery safety standards on how to deal with vibration where hand-transmitted vibration and/or whole-body vibration is identified as a significant hazard.

BS EN 12786 also gives guidance on how to deal with the requirement for declaration of the vibration emission of portable hand-held and/or hand-guided machinery and for mobile machinery.

Who is BS EN 12786 - Drafting of the vibration clauses for type-C standards for? 

BS EN 12786 on requirements for the drafting of the vibration clauses  is relevant to: 

• Technical Committees
• Technical experts
• Writers of machine safety standards
• Certification bodies
• Regulatory bodies
• Local and National authorities

Why should you use BS BS EN 12786 - Drafting of the vibration clauses for type-C standards?

For many machines, vibration is a significant hazard, i.e. a hazard which an assessment has identified as requiring a specific action on the part of the manufacturer or supplier.

The information contained in BS EN 12786 can help writers of standards to address the essential requirements relevant to vibration and is based on the following principles:

• Vibration risk reduction is an integral part of machinery safety
• Machinery shall be so designed and constructed that risks resulting from vibration produced by the machinery are reduced to the lowest level, taking account of technical progress and available means of reducing vibration, in particular at source
• Where vibration is assessed as a significant hazard, the vibration clauses of the type-C standard shall deal with aspects including minimizing the risk through design and protective measures, the provision of information about residual risk and instructions for safe use.

Along with best industry guidance on requirements for the drafting of the vibration clauses in type-C standards, BS EN 12786 also covers informative annexes on guidance on comparative vibration emission data, and Content of Directive 2006/42/EC relevant to vibration.

The provisions of BS EN 12786 are intended to be used by the Technical Committee drafting a type-C standard, while taking account of the specific requirements for the machinery dealt with and of the structure of the type-C standard. It is important that type-C safety standards deal adequately with vibration risks.
