ANSI C63.4 describes the United States standard procedures for measuring RF signals and noise generated by electronic and electrical instruments over the frequency range of 9 kHz to 40 GHz. ANSI C63.4 does not include either generic or product-specific emission limits. The specifications within ANSI C63.4 are harmonized with separate national and international standards utilized with similar intent. ANSI C63.4 is designed to standardize the implementation of emissions testing concerning compliance requirements intended to protect communications services. The standard can be applied to the emissions monitoring of a variety of devices, including both stand-alone units and interconnected units. Notwithstanding other possible uses, this standard is intended to be used for making emission measurements of unintentional radiators (including digital devices and receivers) and for making emission measurements of the digital device portions contained in or used in intentional radiators.

ANSI C63.2 lists requirements for measuring instruments used for electromagnetic interference (EMI) measurements are provided, involving quasi-peak, peak, and average detection in the frequency range 9 kHz to 40 GHz. ANSI C63.2 specifies requirements for measuring receivers [i.e., electromagnetic interference (EMI) receivers and spectrum analyzers with and without preselection] used for radiated and conducted emission measurements. Specifications relate to the measuring equipment only, not transducers like antennas, line impedance stabilization networks (LISNs), or current probes. ANSI C63.2 has been prepared to consolidate the applicable requirements found in CISPR 16-1-1:2010 as well as ANSI C63.2 into one standard to provide a harmonized set of specifications such that the same instrument can be used for measurements in accordance with national and international standards. Additional requirements have been added to address domestic measurement needs as well as requirements for the frequency range 18 GHz to 40 GHz. Buy Standard

CISPR 14-1 specifies the requirements that apply to the emission of radio-frequency disturbances in the frequency range 9 kHz to 400 GHz from appliances, electric tools, and similar apparatus, whether powered by AC or DC (including a battery). Also included in the scope of CISPR 14-1 are separate parts of the above-mentioned equipment such as motors and switching devices (e.g. power or protective relays); however, no emission requirements apply to such separate parts, unless otherwise stated in this standard. The limits in this standard have been determined on a probabilistic basis, to keep the suppression of disturbances economically feasible while still achieving adequate radio protection. In exceptional cases, radio frequency interference may occur, despite compliance with the limits. In such a case, additional provisions may be required. The effects of electromagnetic phenomena relating to the safety of the apparatus are excluded from the scope of this standard.

CISPR 16-1-1 specifies the characteristics and performance of equipment for the measurement of radio disturbance in the frequency range from 9 kHz to 18 GHz. Also, CISPR 16-1-1 provides requirements for specialized equipment for discontinuous disturbance measurements.  In accordance with IEC Guide 107, CISPR 16-1-1 is a basic electromagnetic compatibility (EMC) standard for use by product committees of the IEC. As stated in Guide 107, product committees are responsible for determining the applicability of a basic EMC standard. CISPR and its subcommittee are prepared to co-operate with product committees in the evaluation of the value of particular EMC tests for specific products. The specifications in this document apply to electromagnetic interference (EMI) receivers and spectrum analyzers. The term “measuring receiver” used in this document refers to both EMI receivers and spectrum analyzers (see also 3.7).

CISPR 25 controls the radio environment within the vehicle and was developed in response to the variety of radio receivers that can be installed and/or used in modern motor vehicles. The standard subcommittee holds the view that interference to on-board radio reception caused by equipment on the same vehicle is a quality, or customer satisfaction issue, rather than a matter for government regulation. CISPR 25 defines test methods for use by vehicle manufacturers and suppliers, to assist in the design of vehicles and components and ensure controlled levels of on-board radio frequency emissions. Vehicle test limits are provided for guidance and are based on a typical radio receiver using the antenna provided as part of the vehicle, or a test antenna if a unique antenna is not specified. The frequency bands that are defined do not apply to all regions or countries of the world. For economic reasons, the vehicle manufacturer must be free to identify what frequency bands are applicable in the countries in which a vehicle will be marketed and which radio services are likely to be used in that vehicle. CISPR 25 standard accomplishes the following: Establishes a test method for measuring the electromagnetic emissions from the electrical system of a vehicle; Sets limits for the electromagnetic emissions from the electrical system of a vehicle; Establishes a test method for testing on-board components and modules independent from the vehicle; Sets limits for electromagnetic emissions from components to prevent objectionable disturbance to on-board receivers CISPR 25 contains limits and procedures for the measurement of radio disturbances in the frequency range of 150 kHz to 2500 MHz. The standard applies to any electronic/electrical component intended for use in vehicles, trailers, and devices. Refer to International Telecommunications Union (ITU) publications for details of frequency allocations. The limits are intended to provide protection for

IEC 61000-4-31 relates to the conducted immunity of electrical and electronic equipment to electromagnetic disturbances coming from intended and/or unintended broadband signal sources in the frequency range 150 kHz up to 80 MHz. IEC 61000-4-31 has the status of a basic EMC publication in accordance with IEC Guide 107. IEC 61000-4-31 builds off of the common-mode testing procedures outlined in IEC 61000-4-6 and differential mode testing described in IEC 61000-4-19 (lower frequency range). The object of this standard is to establish a common reference to evaluate the immunity of electrical and electronic equipment when subjected to conducted disturbances caused by intended and/or unintended broadband signal sources on AC mains ports. The test method documented in this standard describes a consistent method to assess the immunity of an equipment or system against a defined phenomenon. Equipment not having at least one AC mains port is excluded. The power ports not intended to be connected to AC mains distribution networks are not considered as “AC mains ports” and therefore are excluded. This standard is applicable only to single-phase equipment having rated input current ≤ 16 A; the application of the broadband disturbance to multiple phase equipment and/or equipment with rated input current > 16 A is under consideration.
