Overview

EN 61786-1:2014/A1:2024 (IEC 61786-1:2013/AMD1:2024) specifies requirements for instruments that measure DC magnetic, AC magnetic and AC electric fields from 1 Hz to 100 kHz with regard to human exposure. This A1 amendment (approved by CENELEC in 2024) updates instrument performance, immunity/emission references, calibration and durability expectations for field meters used in exposure assessment and compliance testing.

Key topics and technical requirements

• Measurement range: Instruments cover DC to 100 kHz frequencies; the amendment clarifies pass-band and usable range requirements so the instrument band covers all frequencies of interest.
• Probes and sensing: Probes should be three‑axis; the weighted-peak assessment method requires three‑axis probes. Magnetic and electric field meters are defined as a probe (field sensing element) plus a detector that reports RMS values.
• Calibration:
  • Primary method referenced in clause 6.2.2; alternative methods detailed in Annex A.
  • At least three field levels per range, equally spaced from 10% to 90% of full scale, should be recorded.
  • Calibration documentation must include the name and serial number, description and condition of items calibrated.
  • The voltage‑injection technique is noted as useful for design/manufacturing stages.
• Readability & schematic: Amendment updates wording for general schematic and readability of scales; Figure 1 now titled “Schematic of a field meter.”
• Immunity and emissions:
  • Immunity requirements reference IEC 61000‑6‑1:2016 (residential/commercial/light‑industrial) and IEC 61000‑6‑2 for industrial environments.
  • Conducted disturbances and radiated emissions are limited in accordance with CISPR 11:2024 (Table 4 and Table 9 respectively); radiated limits cited for Class B Group 1 at 10 m.
• Durability: Instrumentation shall comply with IEC 60721‑3 storage class 1M2, transport class 2M6 and operation class 7M3.
• Electric field meter support: Supports must be made of insulating materials (synthetic/composite/wood); remote viewing or fibre‑optic links are noted for certain probe types.

Applications and users

• Who uses it: instrument manufacturers, calibration laboratories, EMF surveyors, occupational health & safety officers, environmental monitoring agencies, regulatory bodies and researchers.
• Practical applications:
  • Designing and verifying field meters for occupational and public exposure assessments.
  • On‑site EMF surveys near power lines, substations, industrial installations and consumer appliances.
  • Calibration and conformity testing for meters used in compliance with exposure guidelines.
  • Supporting product EMC planning by aligning immunity and emission criteria.

FOREWORD
1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising
all national electrotechnical committees (IEC National Committees). The object of IEC is to promote international
co-operation on all questions concerning standardization in the electrical and electronic fields. To this end and
in addition to other activities, IEC publishes International Standards, Technical Specifications, Technical Reports,
Publicly Available Specifications (PAS) and Guides (hereafter referred to as “IEC Publication(s)”). Their
preparation is entrusted to technical committees; any IEC National Committee interested in the subject dealt with
may participate in this preparatory work. International, governmental and non-governmental organizations liaising
with the IEC also participate in this preparation. IEC collaborates closely with the International Organization for
Standardization (ISO) in accordance with conditions determined by agreement between the two organizations.
2) The formal decisions or agreements of IEC on technical matters express, as nearly as possible, an international
consensus of opinion on the relevant subjects since each technical committee has representation from all
interested IEC Nat
