IEC 60204-32:2023 applies to electrical, electronic, programmable electronic equipment and systems to hoisting machines and related equipment, including a group of hoisting machines working together in a co-ordinated manner. The equipment covered by this document commences at the point of connection of the supply to the electrical equipment of the hoisting machine (crane-supply-switch) and includes systems for power supply and control feeders situated outside of the hoisting machine, for example, flexible cables or conductor wires or conductor bars. This document is applicable to equipment or parts of equipment not exceeding 1 000 V AC or 1 500 V DC between lines and with nominal frequencies not exceeding 200 Hz. This document does not cover all the requirements (for example guarding, interlocking, or control) that are needed or required by other standards or regulations in order to protect persons from hazards other than electrical hazards. Each type of hoisting machine has unique requirements to be accommodated to provide adequate safety. This document does not cover noise risks. Additional and special requirements can apply to the electrical equipment of hoisting machines including those that
– handle or transport potentially explosive material (e.g. paint or sawdust);
– are intended for use in potentially explosive and/or flammable atmospheres;
– have special risks when transporting or moving certain materials;
– are intended for use in mines.
For the purposes of this document, hoisting machines include cranes of all types, winches of all types and storage and retrieval machines. The following product groups are included:

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.

IEC TS 63074:2023(Main)

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).
