Safety of machinery - General principles for design - Risk assessment and risk reduction (ISO/DIS 12100:2024)

Safety of machinery - General principles for design - Risk assessment and risk reduction (ISO/DIS 12100:2024)

ISO 12100:2010 specifies basic terminology, principles and a methodology for achieving safety in the design of machinery. It specifies principles of risk assessment and risk reduction to help designers in achieving this objective. These principles are based on knowledge and experience of the design, use, incidents, accidents and risks associated with machinery. Procedures are described for identifying hazards and estimating and evaluating risks during relevant phases of the machine life cycle, and for the elimination of hazards or sufficient risk reduction. Guidance is given on the documentation and verification of the risk assessment and risk reduction process.
ISO 12100:2010 is also intended to be used as a basis for the preparation of type-B or type-C safety standards.
It does not deal with risk and/or damage to domestic animals, property or the environment.

Sécurité des machines - Principes généraux de conception - Appréciation du risque et réduction du risque (ISO/DIS 12100:2024)

L'ISO 12100:2010 spécifie la terminologie de base, les principes et une méthodologie en vue d'assurer la sécurité dans la conception des machines. Elle spécifie les principes de l'appréciation du risque et de la réduction du risque pour aider les concepteurs à atteindre cet objectif. Ces principes sont fondés sur la connaissance et l'expérience de la conception, de l'utilisation, des incidents, des accidents et des risques associés aux machines. Des procédures sont décrites pour identifier les phénomènes dangereux, et estimer et évaluer les risques au cours des phases pertinentes du cycle de vie des machines, ainsi que pour supprimer les phénomènes dangereux ou ariiver à réduire suffisamment les risques. Des lignes directrices sont fournies sur la documentation et la vérification du processus d'appréciation du risque et de réduction du risque.
L'ISO 12100:2010 est également destinée à servir de document de base pour l'élaboration des normes de sécurité de type B ou de type C.
Elle ne traite pas des risques et/ou des dommages causés aux animaux domestiques, aux biens ou à l'environnement.

This document specifies a methodology and provides related requirements, recommendations and guidance for the design and integration of safety‐related parts of control systems (SRP/CS) that perform safety functions, including the design of software.
This document applies to SRP/CS for high demand and continuous modes of operation including their subsystems, regardless of the type of technology and energy (e.g. electrical, hydraulic, pneumatic, and mechanical). This document does not apply to low demand mode of operation.
NOTE 1        See 3.1.44 and the IEC 61508 series for low demand mode of operation.
This document does not specify the safety functions or required performance levels (PLr) that are to be used in particular applications.
NOTE 2        This document specifies a methodology for SRP/CS design without considering if certain machinery (e.g. mobile machinery) has specific requirements. These specific requirements can be considered in a Type‑C standard.
This document does not give specific requirements for the design of products/components that are parts of SRP/CS. Specific requirements for the design of some components of SRP/CS are covered by applicable ISO and IEC standards.
This document does not provide specific measures for security aspects (e.g. physical, IT-security, cyber security).
NOTE 3        Security issues can have an effect on safety functions. See ISO/TR 22100-4 and IEC/TR 63074 for further information.

—    tool magazine(s);
—    tool changer(s);
—    workpiece handling mechanism(s);
—    powered workpiece clamping mechanism(s);
—    swarf/chip conveyor(s);
—    power-operated door(s);
—    moveable operator cabin(s);
—    additional equipment for turning;
—    additional equipment for grinding.
This document deals with all significant hazards, hazardous situations and events relevant to this type of machinery which can occur during transportation, assembly and installation, setting, operation, cleaning and maintenance, troubleshooting, dismantling or disabling according to ISO 12100, when the machinery is used as intended and under conditions of misuse which are reasonably foreseeable by the manufacturer (see Clause 4).
This document presumes accessibility to the machine from all directions and specifies access conditions to operator positions. It also applies to workpiece transfer devices including transport devices for loading/unloading when they form an integral part of the machine.
