CEN/TC 114 - Safety of machinery

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.

This document addresses how artificial intelligence machine learning can impact the safety of machinery and machinery systems.
This document describes how hazards being associated with artificial intelligence (AI) applications machine learning in machinery or machinery systems, and designed to act within specific limits, can be considered in the risk assessment process.
This document is not applicable to machinery or machinery systems with AI applications machine learning designed to act beyond specified limits that can result in unpredictable effects.
This document does not address safety systems with AI, for example, safety-related sensors and other safety-related parts of control systems.

This document provides assistance to the designer/manufacturer of machinery and related components as to how the system of existing type-A, type-B and type-C machinery safety standards should be applied in order to design a machine to achieve a level of tolerable risk by adequate risk reduction.
This document explains the general principles of ISO 12100 and how this type-A standard is used for practical cases in conjunction with type-B and type-C machinery safety standards.
This document provides assistance to standards-writing committees on how ISO 12100 and type-B and type-C standards relate and explains their function in the risk assessment and risk reduction process according to ISO 12100.
This document includes an overview of existing categories of type-B standards to assist standards readers and writers to navigate the many standards.

This document establishes values for safety distances in both industrial and non-industrial environments to prevent machinery hazard zones being reached. The safety distances are appropriate for protective structures. It also gives information about distances to impede free access by the lower limbs (see Annex B).
This document covers people of 14 years and older (the 5th percentile stature of 14-year-olds is approximately 1 400 mm). In addition, for upper limbs only, it provides information for children older than 3 years (5th percentile stature of 3-year-olds is approximately 900 mm) where reaching through openings needs to be addressed.
NOTE 1  It is not practical to specify safety distances for all persons. Therefore, the values presented are intended to cover the 95th percentile of the population.
Data for preventing lower limb access for children is not considered.
The distances apply when sufficient risk reduction can be achieved by distance alone. Because safety distances depend on size, some people of extreme dimensions will still be able to reach hazard zones even when the requirements of this document are met.
Compliance with the requirements in this document will prevent access to the hazard zone. Nevertheless the user of this document is advised that it does not provide the required risk reduction for every hazard (e.g. hazards related to machine emissions such as ionizing radiation, heat sources, noise, dust).
The clauses covering lower limbs apply on their own only when access by the upper limbs to the same hazard zone is not foreseeable according to the risk assessment.
The safety distances are intended to protect those persons trying to reach hazard zones under the conditions specified (see 4.1.1).
NOTE 2  This document is not intended to provide measures against reaching a hazard zone by climbing over (see ISO 14120:2015, 5.18).

This document gives machine manufacturers guidance on potential security aspects in relation to safety of machinery when putting a machine into service or placing on the market for the first time.

This method is based on a tracer technique and may be operated in all types of test environment (bench, room and field, see ENV 1093-1).   This technique is applicable only if the tracer shows aerodynamic behaviour comparable with the real pollutant (see 7.1.1).  The measurement of the capture efficiency of an exhaust system can serve for:   a) the evaluation of the performance of an exhaust system of a machine;  b) the evaluation of the improvement of an exhaust system;  c) the comparison of exhaust systems for machines of similar design; d) the ranking of exhaust systems according to their capture efficiency; e) the determination of the air flow of an exhaust to achieve a given level of capture efficiency; f) the determination of the state of the art of exhaust systems for machines with respect to the capture efficiency.

ISO 11161:2007 specifies the safety requirements for integrated manufacturing systems (IMS) that incorporate two or more interconnected machines for specific applications, such as component manufacturing or assembly. It gives requirements and recommendations for the safe design, safeguarding and information for the use of such IMSs.
ISO 11161:2007 is not intended to cover safety aspects of individual machines and equipment that may be covered by standards specific to those machines and equipment. Therefore it deals only with those safety aspects that are important for the safety-relevant interconnection of the machines and components. Where machines and equipment of an integrated manufacturing system are operated separately or individually, and while the protective effects of the safeguards provided for production mode are muted or suspended, the relevant safety standards for these machines and equipment apply.

ISO 21469:2006 specifies hygiene requirements for the formulation, manufacture, use and handling of lubricants which, during manufacture and processing, can come into incidental contact (e.g. through heat transfer, load transmission, lubrication or the corrosion protection of machinery) with products and packaging used in the food, food-processing, cosmetics, pharmaceutical, tobacco or animal-feeding-stuffs industries. It is not applicable to substances used as product additives or to those in direct product contact, but confines itself to hygiene without addressing occupational health and safety matters.

The purpose of this report is to give guidance on:
a) how to comply with the relevant legislative requirements, and
b) how to take into account the technical recommendations specified in International, European and National Standards when machines emitting ionizing radiation are designed and built.

This document specifies requirements for the positioning and dimensioning of safeguards with respect to the approach of the human body or its parts towards hazard(s) within the intended span-of-control as follows:
—     the position and dimension of the detection zone(s) of ESPE and pressure-sensitive mats and pressure-sensitive floors;
—     the position of two-hand control devices and single control devices;
—     the position of interlocking guards.
This document also specifies requirements for the positioning of safety-related manual control devices (SRMCD) with respect to the approach of the human body or its parts from within the safeguard space relative to:
—     the position and dimension of the detection zone(s) of ESPE and pressure-sensitive mats and pressure-sensitive floors; and
—     the position and dimension of interlocking guards.
When evaluating the ability of the human body or its parts to access SRMCD from within the intended safeguarded space, the requirements of this document are also applicable to determine the dimensions of safeguard(s). Approaches such as running, jumping or falling, are not considered in this document.
NOTE 1        The values for approach speeds (walking speed and upper limb movement) in this document are time tested and proven in practical experience.
NOTE 2        Other types of approach can result in approach speeds that are higher or lower than those defined in this document.
This document applies to safeguards used on machinery for the protection of persons 14 years and older.
Safeguards considered in this document include:
a)       electro-sensitive protective equipment (ESPE) such as:
—    active opto-electronic protective devices (AOPDs) (see IEC 61496-2);
—    AOPDs responsive to diffuse reflection that have one or more detection zone(s) specified in two dimensions (AOPDDRs-2D) (see IEC 61496-3);
—    AOPDs responsive to diffuse reflection that have one or more detection zone(s) specified in three dimensions (AOPDDRs-3D) (see IEC 61496-3);
—    vision based protective devices using reference pattern techniques (VBPDPP) (see IEC/TS 61496-4-2);
—    vision based protective devices using stereo vision techniques (VBPDST) (see IEC/TS 61496-4-3);
b)       pressure-sensitive mats and pressure-sensitive floors (see ISO 13856-1);
c)        two-hand control devices (see ISO 13851);
d)       single control devices;
e)       interlocking guards (see ISO 14120).
This document is not applicable to:
—     safeguards (e.g. pendant two-hand control devices) that can be manually moved, without using tools, nearer to the hazard zone than the separation distance;
—     protection against the risks from hazards arising from emissions (e.g. the ejection of solid or fluid materials, radiation, electric arcs, heat, noise, fumes, gases);
—     protection against the risks arising from failure of mechanical parts of the machine or gravity falls.
The separation distances derived from this document do not apply to safeguards used solely for presence sensing function.

This document specifies the safety requirements for the integration of machinery into a system. It gives requirements and recommendations for inherently safe design, safeguarding and information for the use of an IMS. This document is not intended to cover safety aspects of individual machines and equipment that can be covered by standards specific to those machines and equipment. Therefore, it deals only with those safety aspects that are important for the safety-relevant interconnection of the machines and components. Where component machines of an integrated machinery system are operated separately or individually, the safety requirements of the relevant safety standards for these machines and equipment apply. This document is also applicable when a modification of an existing IMS results in a new configuration, function, capability or location.

This document specifies principles for the design and selection (independent of the nature of the energy source) of interlocking devices associated with guards and provides guidance on measures to minimize the possibility of defeat of interlocking devices in a reasonably foreseeable manner.
This document covers principles for the design, selection and application of the following:
—     parts of the guards which actuate interlocking devices;
—     trapped key interlocking devices and systems for machinery applications.
NOTE            ISO 14120 specifies general requirements for the design and construction of guards provided primarily to protect persons from mechanical hazards. The processing of the signal from the interlocking device to stop the machine and prevent unexpected start up is covered in ISO 14118, ISO 13849-1 and IEC 62061.

This European Standard defines limits for physical contacts between machines and humans that are caused by movement of the machine as part of its intended use or foreseeable misuse. It covers all types of machines that are designed to function where people can be present without physical barriers and as a result can contact those people. It also covers hazardous mechanical contacts of humans with surroundings that are caused by human fall originated by the movement of a machine. It includes machines that contact people as part of their function and machines that do not require human contact. It encompasses interactions that are intentional or unintentional.
Machines include but are not limited to, fixed robots, mobile robots, collaborative robots, vehicles, machine tools, moving equipment, doors and powered doors, flying robots, exoskeletons, care and domestic servant robots, hand tools.
Requirements that are mandated by local, national or international regulations take precedence over this standard.
Medical devices are not covered by this European Standard.
