CISPR 16-1-4:2019/AMD1:2020 provides Amendment 1 to the specification for radio disturbance and immunity measuring apparatus and methods, with a specific focus on antennas and test sites for radiated disturbance measurements. For engineering teams, laboratories, and compliance functions, it is a relevant technical document when evaluating how measurement setups are defined and maintained for EMC work. CISPR 16-1-4:2019/AMD1:2020 is best used as a supporting reference to the parent document, helping preserve consistency in test planning, technical review, and documented evaluation.

Overview of CISPR 16-1-4:2019/AMD1:2020

This amendment is connected to CISPR 16-1-4:2019 and refines the guidance related to antennas and test sites used in radiated disturbance measurements. Its scope is closely tied to EMC measurement practice, where the configuration and suitability of the test environment can affect technical validation and conformity assessment results. Organizations working on emission requirements, laboratory evaluation, or measurement method control may use CISPR 16-1-4:2019/AMD1:2020 to support operational consistency and review the parent document within a controlled compliance workflow.

Compliance applications of CISPR 16-1-4:2019/AMD1:2020

CISPR 16-1-4:2019/AMD1:2020 is typically relevant in laboratories, certification programs, and engineering documentation processes where radiated disturbance measurements must be performed with defined antennas and test sites. It may be used during procurement review, test setup verification, or preparation for conformity assessment of electrical equipment and electronic systems. Teams involved in EMC testing, technical assessment, and quality workflows often rely on amendment documents like this one to align their procedures with the parent testing standard and maintain controlled testing workflows.

Importance of compliance with CISPR 16-1-4:2019/AMD1:2020

Using CISPR 16-1-4:2019/AMD1:2020 alongside the parent reference can help reduce risk in measurement-based compliance activities by supporting more consistent test conditions and clearer technical documentation. That consistency matters for safety-related review, interoperability checks, engineering validation, and procurement decisions that depend on reliable EMC evidence. In practice, alignment with the amendment can strengthen quality assurance, improve repeatability in laboratory processes, and support regulatory preparation where radiated disturbance data must be defensible and traceable.
