CISPR 16-4-2:2011/AMD2:2018/COR1:2019 provides a supporting compliance reference for measurement instrumentation uncertainty within the wider specification for radio disturbance and immunity measuring apparatus and methods. It is relevant where engineers, laboratories, and procurement teams need a technical document that helps frame uncertainty considerations in EMC testing and documented evaluation. As a corrigendum to Amendment 2 of the parent document, it should be read as a modifying reference connected to CISPR 16-4-2:2011 rather than as a standalone testing standard.

Overview of CISPR 16-4-2:2011/AMD2:2018/COR1:2019

This document addresses the uncertainty aspects associated with measurement instrumentation used in radio disturbance and immunity testing. In practical terms, it supports technical review of how instrument-related uncertainty is considered during EMC laboratory evaluation and conformity assessment work. CISPR 16-4-2:2011/AMD2:2018/COR1:2019 is typically used alongside the parent reference to strengthen operational consistency, improve documented evaluation practices, and support more reliable interpretation of measurement results in engineering and compliance workflows.

Compliance applications of CISPR 16-4-2:2011/AMD2:2018/COR1:2019

Organizations involved in EMC verification activities may use this reference when preparing laboratory procedures, reviewing measurement uncertainty statements, or aligning test reports with procurement and regulatory preparation requirements. It is especially relevant where instrumentation performance must be assessed in controlled test environments, such as radio disturbance and immunity evaluations for electrical equipment and related systems. CISPR 16-4-2:2011/AMD2:2018/COR1:2019 can also support internal technical validation and quality workflows by helping teams maintain a consistent approach to uncertainty-related documentation.

Importance of compliance with CISPR 16-4-2:2011/AMD2:2018/COR1:2019

Attention to this supporting document can reduce ambiguity in EMC test interpretation and improve confidence in conformity assessment preparation. Measurement uncertainty is often a key factor in whether test outcomes are defensible, repeatable, and suitable for technical assessment or product evaluation. Using CISPR 16-4-2:2011/AMD2:2018/COR1:2019 in compliance workflows may help laboratories and manufacturers support quality assurance, improve interoperability decisions, and manage risk when documenting emission and immunity-related results.

• Supports uncertainty handling for EMC measurement instrumentation referenced in the parent document.
• Useful for laboratory procedures, test report review, and documented evaluation of results.
• Helps align measurement practices with conformity assessment and technical compliance workflows.
• Relevant for EMC teams managing verification activities, quality assurance, and risk reduction.
