EMC SC P1848.1 EM Resilience Working Group
Electromagnetic resilience techniques & measures for machinery

(formerly the 1848-MSSV Study Group)

Project Update

The P1848.1 project was approved at the September 20th NesCom meeting. All members of the 1848-MSSV SG are now members of the Working Group. The first Working Group Meeting is scheduled for 2023-12-15. For more information, please contact the WG Secretary.

Scope

The P1848.1 WG will be working on developing a machinery sector version of IEEE 1848™, IEEE Standard for Techniques and Measures to Manage Functional Safety and Other Risks with Regards to Electromagnetic Disturbances. The goal is to focus on the needs of the machinery sector by aligning the language with the standards used in the machinery sector. These standards include:

  • ISO 13849, Safety of machinery — Safety-related parts of control systems (2 parts)
  • IEC 62061, Safety of machinery — Functional safety of safety-related electrical, electronic and programmable electronic control systems

In June 2023, the study group initiated a survey of machine builders to determine the techniques and measures that machine builders commonly use to increase the EM resilience of their designs. You can participate in the survey here. The survey is open until September 30, 2023.

The scope of IEEE 1848™:

1. Overview

This IEEE Standard provides guidance on the assessment and application of techniques and measures that can reduce the risks associated with the interfering effects of electromagnetic disturbances on digital electronic systems, especially safety- or mission-related systems.

When competently selected and applied, a set of such techniques and measures can provide the part of the evidence relevant to EMI required for justifying functional safety decisions and for compliance with functional safety standards (including all applicable parts of IEC 61508 Ed.2:2010 or functional safety standards that are based on IEC 61508; see the partial list in Annex C).

They can also provide part of the evidence relevant to EMI for medical/healthcare systems for which risks are managed in accordance with ISO 14971:2007 [B11].2

This standard supports the adoption of adequate electromagnetic resilience engineering practices throughout the functional safety lifecycle by offering further guidance and practical advice on the application of risk management activities, including the techniques and measures set out in IEC 61000‑1‑2:2016.

While it is primarily intended to be used by those who have responsibilities for functional safety, the methodologies, techniques, and measures it describes can also be used for the reduction of other kinds of risks in any systems that employ electronic technology, such as security risks and non–safety-related risks (for example, risks to the operation of commercial IT systems). However, this standard does not address the risks to human health that can be caused by electromagnetic fields (EMF); HERF (Hazards of Electromagnetic Radiation to Fuel); or HERO (Hazards of Electromagnetic Radiation to Ordnance).

1.1 Scope

This standard provides a set of practical methods for managing functional safety and other risks due to electromagnetic (EM) disturbances throughout the life of a product.

This includes all types of errors, malfunctions or failures in products, equipment, and systems that employ modern digital technologies (i.e., hardware and software).

1.2 Purpose

The purpose of this standard is to provide requirements for the techniques and measures used in the design, verification, and validation of systems, hardware, and software (firmware).

These would be applied where EM disturbances could cause errors, malfunctions, or failures leading to unacceptable risks over the lifetime of equipment, whether safety or any other kind of risk is to be managed.
