IEEE - C63.29

American National Standard for Methods of Measurement of Radio‐Frequency Emissions from Lighting Devices

active, Most Current
Organization: IEEE
Publication Date: 1 December 2022
Status: active
Page Count: 205
scope:

This standard includes procedures for evaluating the compliance of lighting devices with applicable electromagnetic compatibility (EMC) requirements. Test procedures for radiated field strength and conducted disturbance measurements are included, with reference to established standards, where applicable. This standard covers measurement methodologies, but is not intended to describe regulatory limits.

Some regulatory agencies classify lighting devices either as Industrial, Scientific and Medical (ISM) equipment or as digital equipment, depending on its technology. However, if the lighting device includes any wireless modules (intentional radiator, e.g., IEEE 802.11), that portion of the lighting device is usually classified as radio apparatus. This standard includes methods for evaluating the compliance of the lighting device, excluding its radio apparatus portion (if any), with the applicable EMC limits, as specified by the purchasing agency or regulatory authority. Compliance evaluation procedures for radio apparatus are usually subject to other testing procedures; e.g., ANSI C63.10 [B1],9 ANSI C63.26 [B2], and/or additional or other applicable requirements, as specified by the purchasing agency or regulatory authority. This standard does not cover the testing of other types of ISM equipment, incidental or un-intentional radiators.

This standard is also not intended to specify measurement techniques or limits for radio frequency (RF) exposure, electric shock, or electrostimulation due to electromagnetic fields generated by lighting devices.

Measurement methods are included for radiated and alternating current (ac) mains power-line conducted emissions that can be generated by a variety of lighting devices, as described in 1.2. For correctly measuring such emissions, this standard prescribes a sequence of three procedures: frequency identification [for determining the equipment under test (EUT) emission frequencies], exploratory measurements (for determining the set of conditions under which the EUT generates the highest emission relative to the applicable limit), and maximization (manipulation and operation of test instrumentation for determining the level of the highest emission from the EUT). These three processes are defined in 3.1.

Definitions are provided for terms and phrases contained in the text, in which the words do not represent obvious or common usage. In most cases, measurement instrumentation and calibration requirements are only generally characterized in deference to standards dedicated to these subjects, which should be used in conjunction with this standard. The requirements for operation of test samples during measurements are presented for devices in general, as well as for specific types of devices that are frequently measured. Specific requirements for emission test data recording and reporting are also included. The main text is augmented by a series of annexes that provide other useful information or normative requirements.

In this standard, the associated figures are placed at the end of each clause.

The methods in this standard are intended for measuring emissions from the equipment under test in the 9 kHz to 40 GHz frequency range.

Purpose and applications

General

This standard specifies the methods of measurement to be used for evaluating compliance with the applicable radiated and ac mains power-line conducted emissions requirements for lighting devices in wide use (such as luminaires, self-ballasted lamps, dimmers, etc.).

Emission limit requirements shall be obtained from the applicable voluntary or regulatory sources.

Not all clauses in this standard are applicable to all devices that are subject to this standard. The nature of this standard is to specify general methods that shall be applied to all devices in its scope and to supplement these methods with particular requirements for some specific categories of lighting devices. Deviceparticular requirements take precedence over general requirements.

This edition of ANSI C63.29 applies to the following general categories of lighting devices:

a) Active luminaires (i.e., active light fixtures; see 3.1)

b) The lighting components of multi-function equipment if one of the primary functions of this equipment is illumination

c) Ultraviolet (UV) and infrared (IR) radiation equipment

d) Active components (example: ballast, drivers, dimmers, lamps and other; see 3.1) intended exclusively for use with lighting devices or in lighting installations and which are marketed independently

e) Simple advertising signs, i.e., advertising signs other than those in 1.2.2e)4)

EXAMPLE-Neon tube signs, emergency exit signs.

f) Decorative and entertainment lighting

As new lighting technologies mature, this standard might need to be revised or a follow-up amendment might need to be developed to include them.
