Full title and description

IEEE/ANSI C63.30-2021 — American National Standard for Methods of Measurements of Radio‑Frequency Emissions from Wireless Power Transfer Equipment. This standard specifies repeatable, consensus measurement methods, instrumentation, site requirements and reporting practices for evaluating radiated and power‑line conducted radio‑frequency (RF) emissions from wireless power transfer (WPT) equipment operating in the frequency range 9 kHz to 40 GHz. It is a measurement‑methods document and does not define emission limits; limits are obtained from the applicable regulatory or product standards.

Abstract

C63.30-2021 provides standardized procedures to identify emission frequencies, perform exploratory and maximization measurements, and quantify radiated and AC mains conducted emissions from WPT systems (including small consumer chargers, medium‑power appliances and high‑power systems such as vehicle WPT). It covers appropriate test locations (semi‑anechoic chambers, open‑area test sites, ground/earth sites), instrumentation and calibration, extrapolation and distance considerations, test sample operation and configuration, uncertainty reporting, and required test data and reports. Annexes supply device‑specific considerations, examples, and normative details referenced to related C63 series standards and industry specifications.

Scope

This standard applies to methods of measurement used to evaluate radiated field strength and AC mains conducted emissions from WPT equipment where source–client separation distances are within the ranges defined in the document (the first edition addresses WPT with separation distances up to typical short ranges, and provides guidance for small consumer devices through vehicle‑scale WPT). It excludes setting regulatory limits and generally does not address RF exposure compliance procedures. The standard is intended to be used in conjunction with other measurement and instrumentation standards when specific equipment or method details are needed.

Key topics and requirements

• Frequency identification, exploratory measurements and maximization procedures to find worst‑case emissions.
• Radiated emission measurement methods for 9 kHz to 40 GHz, including antenna selection, distance/extrapolation rules and detector functions.
• AC mains conducted emissions measurement methods and use of line impedance stabilization networks (LISNs) or equivalent arrangements.
• Test site descriptions and acceptance criteria for semi‑anechoic chambers, open‑area test sites, ground planes and earth sites.
• Instrumentation, calibration and measurement uncertainty reporting aligned with ISO/IEC 17025 principles and related C63 standards.
• Device configuration, operational modes and procedures to reproduce application‑level conditions for accurate emission characterization.
• Data recording, reporting templates and required information to support conformity assessments and regulatory submissions.
• Annexes with device‑type guidance, harmonization notes with international standards and references to SAE and industry WPT specifications.

Typical use and users

Test and conformity assessment laboratories, EMC engineers in consumer electronics, appliance and automotive sectors, product manufacturers and design teams developing WPT systems, regulatory bodies and certification agencies, and consultants performing emissions characterization and pre‑compliance testing for wireless chargers, industrial WPT equipment and vehicle wireless charging systems.
