Jeremy Procter, Convenor of the European Standards Committee responsible for Machine Guards, and Managing Director of Procter Machinery Guarding, discusses parts 1 and 2 of EN ISO 12100, the machinery safety standard. [ Note that EN ISO 12100-1 and EN 12100-2 have both been superseded by - Ed, 31 December 2010] EN ISO 12100 Safety of machinery - Basic concepts, general principles for design is one of the most important machinery safety standards. It is harmonised to the Machinery Directive, so complying with its requirements (and those of other relevant harmonised standards) will generally be the shortest route to demonstrating that the Essential Health and Safety Requirements of the Directive have been met. EN ISO 12100 consists of two parts; Part 1 deals with Basic terminology, methodology and Part 2 is the Technical principles.
Each part states that the other is 'indispensable for the application of this document.' EN ISO 12100-1:2003 and EN ISO 12100-2:2003 are Type A standards (basic safety standards) and therefore have a dual purpose: they are for use when designing machinery and they are also for use in developing Type B and Type C standards.

Note, however, that a Type B standard (eg EN ISO 13849-1, Safety of machinery, Safety-related parts of control systems, Part 1: General principles for design) or a Type C standard (eg BS56 Specification for continuous mechanical handling equipment - Safety requirements, conveyors and elevators with chain elements - Examples for guarding of nip points) takes precedence if it deviates from any provision within EN ISO 12100-2 or any other applicable Type A standard.

Both parts of EN ISO 12100 also recommend that the standard be incorporated in training courses and manuals to 'convey basic terminology and general design methods to designers.' EN ISO 12100-1 Looking in detail at Part 1, there are three main clauses in addition to the scope and normative references. Clause 3 of EN ISO 12100-1, extending to around seven pages, is devoted to terms and definitions. This covers everything from 'machinery', 'hazard' and 'risk' to 'adequate risk reduction', 'common cause failures' and 'common mode failures.' Hp Compaq 510 Drivers For Windows 7 32bit.
Although Clause 3 does not contain a formal definition of a machine's lifecycle, Clause 5.3 explains this in some detail. Clause 4, 'Hazards to be taken into account when designing machinery,' can be treated as an extensive checklist of hazards, ranging from mechanical, electrical and thermal hazards to hazards generated by noise, vibration and 'neglecting ergonomic principles in machine design.' Nevertheless, the standard acknowledges that there is a more detailed list of hazards and hazardous situations available in ISO 14121 (now EN ISO 14121-1:2007 Safety of machinery. Risk assessment. Clause 5, 'Strategy for risk reduction,' contains what might be termed the real 'meat' of the standard. Sub-clause 5.1.3 and the corresponding flowchart (figure 2) lay down the basic steps to be taken: • Specify the limits and the intended use of the machine; • Identify the hazards and associated hazardous situations; • Estimate the risk, for each identified hazard and hazardous situation; • Evaluate the risk and take decisions about the need for risk reduction; • Eliminate the hazard or reduce the risk associated with the hazard by protective measures. Subsequent sub-clauses address each of these steps in more detail.
Another fundamental concept that is introduced (in Clause 5.4) is the 3-step approach to eliminating or reducing risk by protective measures. These three steps are: • Step 1: Inherently safe design measures • Step 2: Safeguarding and complementary protective measures • Step 3: Information for use (both at the machine and in the instruction book) 'Adequate risk reduction' is defined in Clause 3 ('risk reduction at least in accordance with the legal requirements under consideration of the current state of the art') but Clause 5.5, 'Achievement of risk reduction objectives,' gives a practical checklist that users will find more helpful. Beware, however, that there is a reference to the 'lowest practicable' level of risks from hazards, and the standard does not define this term. On the subject of risk reduction, the recently published ISO/TR 14121-2:2007 Safety of machinery - Risk assessment - Part 2: Practical guidance and examples of methods' is intended to assist designers in complying with EN ISO 12100 by providing additional guidance on the selection of appropriate protective measures for achieving safety. While the foregoing discusses the body of Part 1 of the standard, there are also some additional information included. Annex A provides a schematic representation of a machine, though this is likely to be of limited use to most readers, and there are 14 pages of a trilingual (English, German and French) index of specific terms and expressions used in the standard, which is unlikely to be of use to most machine designers.
