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 corona charging method is suitable for evaluating the ability of materials, for example textiles, packaging, etc., to dissipate charge from their own surfaces. The charged metal plate method is suitable for evaluating the ability of materials and objects such as gloves, finger cots, hand tools, etc. to dissipate charge from conductive objects placed on or in contact with them. The charged plate method might not be suitable for evaluating the ability of materials to dissipate charge from their own surfaces. In addition to its general application, this horizontal standard is also intended for use by technical committees in the preparation of standards in accordance with the principles laid down in IEC Guide 108.

IEC 61340-4-4:2012 specifies requirements for flexible intermediate bulk containers (FIBC) between 0,25 m3 and 3 m3 in volume, intended for use in hazardous explosive atmospheres. The explosive atmosphere may be created by the contents in the FIBC or may exist outside the FIBC. The requirements include: - classification and labelling of FIBC; - classification of inner liners; - specification of test methods for each type of FIBC and inner liner; - design and performance requirements for FIBC and inner liners; - safe use of FIBC (including those with inner liners) within different zones defined for explosion endangered environments, described for areas where combustible dusts are, or may be, present (IEC 60079-10-2), and for explosive gas atmospheres (IEC 60079-10-1); - procedures for type qualification and certification of FIBC, including the safe use of inner liners. The requirements of this standard are applicable to all types of FIBC and inner liners, tested as manufactured, prior to use and intended for use in hazardous explosive atmospheres: Zones 1 and 2 (Groups IIA and IIB only) and Zones 21 and 22. For some types of FIBC, the requirements of this standard apply only to use in hazardous explosive atmospheres with minimum ignition energy of 0,14 mJ or greater and where charging currents do not exceed 3,0 μA. Compliance with the requirements specified in this standard does not necessarily ensure that hazardous electrostatic discharges, e.g. cone discharges, will not be generated by the contents in FIBC. Compliance with the requirements of this standard does not mitigate the need for full risk assessment. For example, metal and other conductive powders and toner powders may require additional precautions to prevent hazardous discharges from the powders. Test methods included in this standard may be used in association with other performance requirements, for example when a risk assessment has shown the minimum ignition energy of concern is less than 0,14 mJ, charging currents are greater than 3,0 μA, or the ambient conditions are outside of the range specified in this standard. Compliance with the requirements specified in this standard does not necessarily ensure that electric shocks to personnel will not occur from FIBC during normal use. This second edition cancels and replaces the first edition, published in 2005, and constitutes a technical revision. The main changes with respect to the first edition are listed below: a) Adoption of a type classification system for FIBC based on four types: A, B, C and D. b) Guidance for safe use of FIBC in relation to hazardous areas and hazardous zones defined in IEC 60079-10-1 and IEC 60079-10-2 is added. c) Resistance to groundable points and electrical breakdown voltage measurements on FIBC shall be measured at low humidity only. d) Requirements for labelling FIBC are changed to improve clarity and ease of recognition by end users. e) Classification, performance requirements and guidance for safe use of inner liners in combination with FIBC are added. f) An informative annex giving guidance on test methods for quality control and inspection testing is added.

This standard does not address protection from electromagnetic interference (EMI), radio frequency interference (RFI), electromagnetic pulsing (EMP) nor protection of volatile materials.

Applies to activities that: manufacture, process, assemble, install, package, label, service, test, inspect, transport or otherwise handle electrical or electronic parts, assemblies and equipment susceptible to damage by electrostatic discharges greater than or equal to 100 V human body model (HBM). Provides the requirements for an ESD control program. The user should refer to IEC 61340-5-2 for guidance on the implementation of this standard. Does not apply to electrically initiated explosive devices, flammable liquids, gases and powders. The purpose of this standard is to provide the administrative and technical requirements for establishing, implementing and maintaining an ESD control program (hereinafter referred to as the 'program'). The main changes with respect to the previous edition are listed below: This version of IEC 61340-5-1 focuses on the requirements for an ESD control program. In addition, this version of IEC 61340-5-1 has been aligned with other major ESD control program standards used throughout the world.

Describes the discharge current waveforms used to simulate human body model (HBM) electrostatic discharges (ESD) and the basic requirements for equipment used to develop and verify these waveforms. This standard covers HBM ESD waveforms for use in general test methods and for application to materials or objects, electronic components and other items for ESD withstand-test or performance-evaluation purposes. The specific application of these HBM ESD waveforms to non-powered semiconductor devices is covered in IEC 60749-26. The waveforms defined in this standard are not intended for use in the testing of powered electronic systems for electromagnetic compatibility (EMC), which is covered in IEC 61000-4-2. The major change of this document is that it no longer contains the application to semiconductor devices

Describes the discharge current waveforms used to simulate machine model (MM) electrostatic discharges (ESD) and the basic requirements for equipment used to develop and verify these waveforms. This standard covers MM ESD waveforms for use in general test methods and for application to materials or objects, electronic components and other items for ESD withstand test or performance evaluation purposes. The specific application of these MM ESD waveforms to non-powered semiconductor devices is covered in IEC 60749-27. The major change of this document is that it no longer contains the application to semiconductor devices.

Describes procedures for evaluating the ignition risk presented by electrostatic discharges from FIBC to flammable or explosive environments. The requirements of this standard are applicable to all types of FIBC, tested as manufactured, prior to usage, intended for use without liners in flammable or explosive environments with minimum ignition energy of more than 0,14 mJ, and where the charging currents do not exceed 3,0 A. NOTE 0,14 mJ is the minimum ignition energy normally quoted for methanol. Although more sensitive materials exist, methanol has the lowest minimum ignition energy of any material that is likely to be present when FIBC are emptied. 3,0 uA is the highest charging current likely to be found in common industrial processes. This combination of minimum ignition energy and charging current represents the most severe conditions that might be expected in practice. Compliance with the requirements of this standard does not mitigate the need for full risk assessment. The test methods included in this standard may be used in association with other performance requirements, for example when a risk assessment has shown the minimum ignition energy of concern is less than 0,14 mJ or charging currents greater than 3,0 uA are present.
