Whoops wrong standard! My brain went into autocorrect.
Thanks to John W for the catch From: James Pawson (U3C) <ja...@unit3compliance.co.uk> Sent: Monday, September 9, 2024 9:33 AM To: EMC-PSTC@LISTSERV.IEEE.ORG Subject: Re: [PSES] : IEC 61000-2-4 scope Hi Ralph ISO 10605 tends to be used for ESD in automotive. It is still based on the HMM generator used in IEC 61000-4-2 but with four different discharge networks and slightly different test methods. You might be able to find an older edition via Google for research purposes. If the client’s customer has it in their (commercial not legal) procurement specification then I wish you luck in trying to argue about applicability! 😊 All the best James James Pawson Managing Director & EMC Problem Solver Unit 3 Compliance Ltd EMC : Environmental & Vibration : Electrical Safety : CE & UKCA : Consultancy <http://www.unit3compliance.co.uk/> www.unit3compliance.co.uk | <mailto:ja...@unit3compliance.co.uk> ja...@unit3compliance.co.uk +44(0)1274 911747 | +44(0)7811 139957 2 Wellington Business Park, New Lane, Bradford, BD4 8AL Registered in England and Wales # 10574298 Office hours: Every morning my full attention is on consultancy, testing, and troubleshooting activities for our customers’ projects.

Pertinent portion underlined. IEC 61000-2-4:2024 Electromagnetic compatibility (EMC) - Part 2-4: Environment - Compatibility levels in power distribution systems in industrial locations for low-frequency conducted disturbances Standard Details IEC 61000-2-4:2024 is available as IEC 61000-2-4:2024 RLV which contains the International Standard and its Redline version, showing all changes of the technical content compared to the previous edition. IEC 61000-2-4:2024 is related to conducted disturbances in the frequency range from 0 kHz to 150 kHz. It gives compatibility levels in differential mode (L-L and L-N) for industrial locations, with a nominal voltage up to 35 kV and a nominal frequency of 50 Hz or 60 Hz. NOTE 1 Industrial locations are defined in 3.1.8. Power distribution systems on ships, aircraft, offshore platforms and railways are not included. -- Ken Javor Ph: (256) 650-5261 From: Ralph McDiarmid <rmm.priv...@gmail.com <mailto:rmm.priv...@gmail.com> > Reply-To: <rmm.priv...@gmail.com <mailto:rmm.priv...@gmail.com> > Date: Friday, September 6, 2024 at 1:15 PM To: <EMC-PSTC@LISTSERV.IEEE.ORG <mailto:EMC-PSTC@LISTSERV.IEEE.ORG> > Subject: Re: [PSES] : IEC 61000-2-4 scope My turn to ask a question to the group of experts. Reference: IEC 61000-2-4:2024 Electromagnetic compatibility (EMC) - Part 2-4: Environment - Compatibility levels in power distribution systems in industrial locations for low-frequency conducted disturbances My client would like to know if standard IEC 61000-2-4 is applicable to an inverter that is intended for permanent installation in a motor vehicle. The inverter has no connection to a.c. mains and does not have an a.c. input power port. It’s merely a 24Vdc to 230Vac/50Hz inverter. I think this IEC standard is clearly out of scope for this class of equipment, but if client’s customer insists (a big automotive manufacturer) I’d like to be able craft a technical justification to waive application of the standard. The standard appears only to address conducted disturbances which may be present on non-public (industrial) a.c. power networks and the EMC immunity of equipment connected to those networks.
