Welcome to Cherry Clough Consultants Ltd
Independent consultants helping designers, manufacturers, system integrators, installers, operators and users deal quickly and cost-effectively with real-life EMI and compliance with EMC and Safety Directives. All: Applications; Industries; Sizes/scales; Worldwide.
Our SI, PI & EMC design techniques have been very well-proven for 35+ years to significantly reduce design and development risk (time and cost); overall cost of manufacture; warranty costs and financial risks, from DC to 24GHz (so far!) – whatever the relevant EMC standards: from the 'generics' to the toughest: e.g. DEF STAN 59-411 Land Class A.
And our well-proven guidelines for reducing the Functional Safety and other risks that could be caused by EMI (even when all EMC tests are passed) have now been standardised by the IET, IEEE and/or IEC.

Praveen Rao is our sixth Associate, based in Australia and India
I'm now very pleased indeed to introduce Praveen Rao,

And his offices in India help local manufacturers cope with the new Indian Regulations,
and help them succeed in global markets.

For what we used to call "EMC for Functional Safety"...
The current state of the art is: IEEE Std 1848-2020, "Techniques & Measures to Manage Functional Safety and Other Risks With Regard to Electromagnetic Disturbances"
published as a full IEEE Standard on 27 April 2021: https://standards.ieee.org/standard/1848-2020.html
The MEDICAL EMC STATE OF THE ART is now: IEC TS 60601-4-6:2024
Medical electrical equipment - Part 4-6: Guidance and interpretation - Voluntary guidance to help achieve basic safety and essential performance with regard to the possible effects of electromagnetic disturbances.
IEC TS 60601-4-6:2024 provides practical methods to help achieve basic safety and essential performance with regard to the possible effects of EM disturbances throughout the expected service life of medical equipment or systems.
These practical methods attempt to address all of the different types of errors, malfunctions or failures that can be caused by EM disturbances, and the purpose of this document is to provide recommendations for the techniques and measures used in the design, verification, and validation of systems, hardware, software, and firmware used in medical equipment or systems to help achieve Basic Safety and Essential Performance with regard to the EM disturbances that could occur throughout their expected service lives.
