Electrostatics - Part 5-4: Protection of electronic devices from electrostatic phenomena - Compliance verification

IEC TR 61340-5-4:2019(E) describes compliance verification testing for technical items that are included in ESD control programs, such as those specified in IEC 61340-5-1.
Test methods, in the main body of this document, are based on those specified in IEC 61340-5-1 and other parts of IEC 61340, and are simplified where necessary for the purposes of compliance verification, to be performed by competent personnel.
Additional compliance verification tests and procedures within the scope of this document are described in Annexes B to G.
Users can, by reference to this document in their compliance verification plan, adopt the necessary test methods described herein without change or addition. Alternatively, tests methods described in this document can be adapted to match the requirements of their own ESD control program, provided deviations in equipment or procedure are documented in their compliance verification plan.
Product qualification is excluded from the scope of this document.
