The Safety Handbook ABB Jokab - Automation Systems and Controls

Directives andStandardsDirectives and standards are of great importance for manufacturersof machines and safety components. EU Directives giving requirementsfor the minimum level of health and safety are mandatory formanufacturers to fulfil. In every member country the Directives areimplemented in each countries legislation.Machines which have been put on the market since december 29,2009, must comply with the new Machinery Directive 2006/42/EC.Before that, the old Machinery Directive 98/37/EC was valid.The objectives of the Machinery Directive, 2006/42/EC,are to maintain, increase and equalise the safety level ofmachines within the members of the European Community.Based on this, the free movement of machines/productsbetween the countries in this market can be achieved. TheMachinery Directive is developed according to “The NewApproach” which is based on the following principles• The directives give the basic health and safety requirements,which are mandatory.• Detailed solutions and technical specifications are foundin harmonised standards.• Standards are voluntary to apply, but products designedaccording to the harmonised standards will fulfil the basicsafety requirements in the Machinery Directive.Harmonised standardsHarmonised standards give support on how to fulfil therequirements of the Machinery Directive. The relationshipbetween the Machinery Directive and the harmonised standardsis illustrated by the diagram below.Within ISO (The International Organization for Standardization)work is also going on in order to harmonisethe safety standards globally in parallel with the Europeanstandardisation work. One consequence of this is that manyexisting EN-standards will, when revised, change number.For example, EN 954-1 will when revised change number toEN ISO 13849-1. Due to the New Machinery Directive,all harmonised standards will be reviewed and revised tosome extent.ABB Jokab Safety takes an active part in the workinggroups both for the ISO and EN standards.Examples of standardsThe MachineryDirective2006/42/ECA-standardB1-standardB2-standardGiving basic concepts, principles for design, and general aspects that canbe applied to all machineryB1: Standards on particular safety aspects (e.g. safety distances, surfacetemperature, noise)B2: Standards on safeguards,e.g. two-hand controls, interlocking devices,pressure sensitive devices, guardsDealing with detailed safety requirements for a particularmachine or group of machinesC-standard1:6ABB
