Identifying how the EUT should behave during immunity testing (e.g., normal performance vs. temporary loss of function). Conclusion
If your device is for , you may be exempt from certain surge and EFT testing if it operates below 30 V AC or 60 V DC. Always check Clause 4 of the PDF.

Tests the device against airborne radio-frequency signals (like cell phones or walkie-talkies).

For CE marking, you must use the version because it includes the European "Z Annexes" (Z Annex ZZ references the EU EMC Directive). The pure IEC version does not. However, the technical content is nearly identical.
Engineers, compliance officers, and laboratory managers frequently seek an official copy of the standard to ensure product deployment follows proper guidelines. The document is widely published in secure PDF format by authorized regional bodies. Understanding its core classifications, testing protocols, and evolution is critical for executing an effective hardware compliance strategy.

If you are looking for specific test levels for a particular type of equipment (e.g., handheld lab tools vs. fixed industrial controllers), or if you need to know how to handle multi-frequency interference, let me know, and I can provide tailored technical details.
