Safety of machinery – Electro-sensitive protective equipment - Part 5: Particular requirements for radar-based protective devices

IEC TS 61496-5:2023 provides particular requirements for the design, construction and testing of non-contact electro-sensitive protective equipment (ESPE) designed specifically to provide whole-body detection of a person or persons as part of a safety-related system, employing radar protective devices (RPDs) responsive to diffuse reflection of radar signals for the sensing function using frequency-modulated continuous-wave (FMCW) technique. Special attention is directed to features which ensure that an appropriate safety-related performance is achieved. An ESPE can include optional safety-related functions, the requirements for which are given in Annex A of IEC 61496-1:2020 and Annex A of this document.
The requirements given in this document are related to the detection of adult persons being present in an industrial manufacturing environment.
This document does not specify the dimensions or configurations of the detection zone and its disposition in relation to hazardous parts for any particular application, nor what constitutes a hazardous state of any machine. It is restricted to the functioning of the ESPE and how it interfaces with the machine.
This document does not consider the aspects of a moving RPD application. Additional consideration can be necessary, if the RPD supplier specifies the RPD for use on moving application.
Additional requirements and tests can apply if setup of the RPD differs from Figure 2 and Figure 4.
Where this document does not contain all necessary provisions, IEC TS 62998-1 is used.
For those aspects not considered in this document it is also possible to additionally use provisions from IEC TS 62998-1.
Excluded from this document are RPDs that employ electromagnetic radiation outside the range 9 GHz to 81 GHz (identified as subset of band 10 and band 11 in accordance with ITU Radio Regulations). For sensing devices that employ electromagnetic radiation outside this range, this document can be used as a guide. National regulations can limit the available frequencies.
This document can be relevant to applications other than those for the protection of persons, for example for the protection of machinery or products from mechanical damage. In those applications, different requirements can be appropriate, for example when the materials to be recognized by the sensing function have different properties from those of persons.
This document does not deal with requirements for ESPE functions not related to the protection of persons (e.g. using sensing unit data for navigation).
While a data interface can be used to control optional safety-related ESPE functions (Annex A), this document does not provide specific requirements. Requirements for these safety-related functions can be determined by consulting other standards (for example, IEC 61508, IEC 62046, IEC 62061, and ISO 13849-1).
This document does not deal with EMC emission requirements.

Safety of machinery - Safety-related sensors used for the protection of persons - Part 3: Sensor technologies and algorithms

IEC TS 62998-3:2023 gives guidance on:
- analysis of sensor technologies of different wavelength ranges, measurement methods, and the sensing unit arrangement in an SRS, respectively the arrangement of SRSs in an SRSS;
- representative physical properties of safety-related objects with due consideration of their material characteristics and the sensor technology/technologies used in an SRS/SRSS to achieve the detection capability and comparable results during verification and validation;
- analysis of the interference of objects present in the surrounding on the safety related objects and thereby the influence on the dependability of the detection capability;
- use of algorithms during design, development and maintenance to achieve appropriate detection capability and dependability of detection;
- appropriate use of algorithms during the integration of SRS or SRSS by the integrator to improve execution of measurement information or provide decision information derived from measurement information.
If an SRS/SRSS uses sensor technologies not stated in this document, then the generic approach in accordance with IEC TS 62998-1 applies.

IEC TS 63394:2023(Main)
Safety of machinery - Guidelines on functional safety of safety-related control systems

IEC TS 63394:2023 In the context of the safety of machinery, the sector standard IEC 62061, along with ISO 13849 1, provides requirements to manufacturers of machines for the design, development and integration of safety-related control systems (SCS) or safety-related parts of control systems (SRP/CS), depending on technology used (mechanical, pneumatic, hydraulic or electrical technologies) to perform safety function(s). This document does not replace ISO 13849-1 and IEC 62061. This document gives additional guidance to the application of IEC 62061 or ISO 13849-1.
This document:
– gives guidelines and specifies additional requirements for specific safety functions based on the methodology of ISO 12100, which are relevant in machinery and respecting typical boundary conditions of machinery;
– considers safety functions which are designed for high demand mode of operation yet are rarely operated, called rarely activated safety functions;
– gives additional information for the calculation of failure rates using other (non-electronic) technologies based e.g. on Weibull distribution, because all the formula defined in IEC 62061 and ISO 13849-1 are based on exponential distribution.
Therefore, the basis for these guidelines and additional requirements is
– a typical classification of safety functions;
– a consideration of typical architectures used for designing safety functions;
– a consideration of modes of operation of safety functions;
– the derivation and evaluation of PFH formulas for subsystems considering the used technology.
This document does not address low demand mode of operation according to IEC 61508.
This document does not take into account either layer of protection analysis (LOPA) or basic process control system (BPCS), according to IEC 61511 as a risk reduction measure.
This document considers all lifecycle phases of the machine regarding functional safety, and SCS or SRP/CS.

Safety of machinery - Security aspects related to functional safety of safety-related control systems

IEC TS 63074:2023 identifies the relevant aspects of the IEC 62443 series related to security threats and vulnerabilities that are considered for the design and implementation of safety-related control systems (SCS) which can lead to the loss of the ability to maintain safe operation of a machine.
Typical security aspects related to the machine with potential relation to SCS are:
– vulnerabilities of the SCS either directly or indirectly through the other parts of the machine which can be exploited by security threats that can result in security attacks (security breach);
– influence on the safety characteristics and ability of the SCS to properly perform its function(s);
– typical use case definition and application of a corresponding threat model.
Non-safety-related aspects of security threats and vulnerabilities are not considered in this document.
The focus of this document is on intentional malicious actions. However, intentional hardware manipulation (e.g. wiring, exchange of components) or foreseeable misuse by physical manipulation of SCS (e.g. physical bypass) is not considered in this document.
This document does not cover security requirements for information technology (IT) products and for the design of devices used in the SCS (e.g., product specific standards can be available, such as IEC TS 63208).

IEC TR 63161:2022(Main)
Assignment of a safety integrity requirements - Basic rationale

IEC TR 63161:2022 can be used where a risk assessment according to ISO 12100 has been conducted for a machine or process plant and where a safety related control function has been selected for implementation as a protective measure against specified hazards. This document describes an example basic logical rationale to assign a safety integrity requirement to the selected function.
The description is generic and as far as reasonably possible independent from any specific tool or method that can be used for assignment of a safety integrity requirement. The requirement can be expressed as a safety integrity level (SIL), or performance level (PL).
An example basic rationale is described that is embodied by such methods and tools, as far as they follow a risk based quantitative approach.
Conversely, the logic described in this document can be used as a reference for assessing specific methods or tools for safety integrity assignment. This can clarify how far the respective tool/method is following a risk based quantitative approach, and where deviations from that approach are imposed by other considerations. In real applications, the quantitative risk based approach can be modified or overridden by other considerations in many cases and for good reasons. It is not within the scope of this document to discuss or evaluate such reasons. Usually the reasons for deviations from a given tool or method from a quantitative logic are provided, so that this can be discussed in the proper frame.
Examples for such analyses are provided for common assignment tools in the format of risk graphs and risk matrices.
This document can be used for safety related control functions in all modes of application: continuous mode, high demand mode and low demand mode of application.
