IEC 62305-3:2024 provides the requirements for protection of a structure against physical damage by means of a lightning protection system (LPS), and for protection against injury to human beings due to touch and step voltages in the vicinity of an LPS (see IEC 62305-1). This document is applicable to the: a) design, installation, inspection and maintenance of an LPS for structures without limitation of their height, b) establishment of measures for protection against injury to human beings primarily due to touch and step voltages. This third edition cancels and replaces the second edition published in 2010. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition: a) Minimum thicknesses of metal sheets or metal pipes are given in Table 4 for air-termination systems where it is necessary to prevent hot-spot problems. Maximum temperature rises ΔT (K) and time duration t50 (s) for different thicknesses and long strokes are also given. b) Cross-reference to the IEC 62561 series is made for the use of reliable, stable, safe and appropriate LPS components. c) The application of two methods – general and simplified – for separation distance calculation is clarified. d) Some changes to the requirements for continuity of steel reinforcement are made. e) Annex C is revised to address comments from IEC subcommittee 31J. f) Revision of positioning of air-termination conductors are modified according to the three accepted methods. A more precise description of the methods for positioning of the air-termination systems are made according to the complexity of structures to be protected. The main text has been simplified, Annex A has been deleted and all detailed information has been moved to Annex D. g) Information on the protection of green roofs is introduced in Annex D. h) Information on the protection of protruding parts on facades of tall buildings is introduced in Annex D. i) a new definition of “electrically insulated LPS” has been introduced to distinguish it from an LPS both electrically and physically isolated from the structure, with a slight modification of the other LPS definitions.

This part of IEC 62305 provides general principles for the protection of structures against lightning, including their installations and contents, as well as persons. The following cases are outside the scope of this document: - railway systems; - vehicles, ships, aircraft, offshore installations; - underground high-pressure pipelines; − pipe, power and telecommunication lines placed outside the structure; − nuclear power plants. NOTE 1 In these cases, structures usually fall under special regulations produced by various specialized authorities. The IEC 62305 series is generally considered as a minimum requirement for these structures. For structures (subsidiary or others) not falling under such special regulations, IEC 62305 still applies. NOTE 2 Lightning protection of wind turbines is also covered by IEC 61400-24 [14]. NOTE 3 Until any further information by CIGRE is available the lightning current parameters described in this standard may be applied also for offshore installations.

IEC 62305-2:2024 is applicable to the risk management of a structure due to lightning flashes to earth. Its purpose is to provide a procedure for the evaluation of such a risk. Once an upper tolerable limit for the risk has been selected, this procedure provides a means for the selection of appropriate protection measures to be adopted to reduce the risk to or below the tolerable limit. This third edition cancels and replaces the second edition, published in 2010. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition: a) The concept of a single risk, to combine loss of human life and loss due to fire, has been introduced. b) The concept of frequency of damage that can impair the availability of the internal systems within the structure has been introduced. c) The lightning ground strike-point density NSG has been introduced replacing the lightning flash density NG in the evaluation of expected average annual number of dangerous events. d) Reduction of a few risk components can be achieved by the use of preventive temporary measures activated by means of a thunderstorm warning system (TWS) compliant with IEC 62793. The risk of direct strike to people in open areas has been introduced, considering the reduction of that risk using a TWS.

IEC 61340-5-1:2024 applies to organizations that: manufacture, process, assemble, install, package, label, service, test, inspect, transport, or otherwise handle electrical or electronic parts, assemblies and equipment with withstand voltages greater than or equal to 100 V human body model (HBM) and 200 V charge device model (CDM). Also, protection from isolated conductors is addressed by limiting the voltage on isolated conductors to less than 35 V. ESDS with lower withstand voltages can require additional control elements or adjusted limits. Processes designed to handle items that have lower ESD withstand voltage(s) can still claim compliance to this document. This document provides the requirements for an ESD control program. IEC TR 61340-5-2 provides guidance on the implementation of this document. This document does not apply to electrically initiated explosive devices, flammable liquids, gases, and powders. The purpose of this document is to provide the administrative and technical requirements for establishing, implementing, and maintaining an ESD control program (hereinafter referred to as the “program”). This edition includes the following significant technical changes with respect to the previous edition: a) definitions have been added to the document; b) updates to product qualification requirements; c) subclause 5.3.3 now includes a reference to groundable static control garment systems; d) Table 2 was replaced; e) subclause 5.3.4.2 was updated to define what an insulator is; f) subclause 5.3.4.3 was updated to include a definition for isolated conductor; g) Table 3 was updated, technical items added, including a reference to IEC 61340-5-4 for compliance verification testing; h) Table 4 was added as a summary of the requirements in IEC 61340-5-3 and to include requirements for compliance verification of packaging; i) Annex A was replaced: the former Annex is no longer required.

In the context of the safety of machinery, the sector standard IEC 62061 as well as ISO 13849 1 provide 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; NOTE 1 IEC 62061:2021 completely covers high demand. However, other safety functions related to the protection of the machine itself and indirectly of persons are considered more in detail in this document. 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. NOTE 2 These guidelines can also be used for application of ISO 13849-1 for the design process of SRP/CS. 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. NOTE 3 The user of the machine needs information from the machine manufacturer for the safe operation of the machine, e.g. useful lifetime of components, maintenance information, testing of safety functions if necessary.

This technical specification 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).
