IEC 62906-5-4:2018/COR1:2022

IEC 62906-5-4:2018/COR1:2022 is a corrigendum linked to the document titled Corrigendum 1 - Laser display devices - Part 5-4: Optical measuring methods of colour speckle, and it should be read as a supporting reference to the parent publication IEC 62906-5-4:2018. For teams involved in laboratory evaluation, engineering documentation, or conformity assessment, this correction can matter when optical measurement results, test reports, or procurement specifications rely on the exact wording of the parent technical document.

What is IEC 62906-5-4:2018/COR1:2022?

IEC 62906-5-4:2018/COR1:2022 is a corrigendum that updates or corrects the published guidance for optical measuring methods of colour speckle in laser display devices. As a related document rather than a standalone technical specification, it is typically used alongside the parent reference during technical review, verification activities, and compliance workflows. For organizations assessing display performance or preparing documented evaluation records, the corrigendum helps ensure the underlying method is interpreted and applied consistently.

Applications of IEC 62906-5-4:2018/COR1:2022

This corrigendum is relevant where laser display devices are evaluated using optical methods for colour speckle characterization. It may be used by test laboratories, product engineering teams, certification bodies, and procurement groups reviewing performance evidence for display-related equipment. In practice, it supports testing workflows, technical validation, and engineering specification checks where accurate alignment with the parent document is important. It can also assist organizations maintaining controlled technical documents for product evaluation and regulatory preparation.

Why is IEC 62906-5-4:2018/COR1:2022 important?

Accurate corrigenda are important because small textual corrections can affect measurement interpretation, reporting consistency, and conformity assessment preparation. IEC 62906-5-4:2018/COR1:2022 helps reduce the risk of using outdated or ambiguous wording when performing optical measurements of colour speckle. For quality assurance and compliance workflows, that supports more reliable engineering validation, clearer laboratory procedures, and better operational consistency across test reports, procurement reviews, and technical assessments tied to laser display device performance.

• Supporting correction to the parent document IEC 62906-5-4:2018 for optical measurement of colour speckle
• Useful for laboratories and engineering teams aligned to display testing and verification activities
• Helps maintain consistency in documented evaluation, reporting, and conformity assessment work
• Relevant to procurement and compliance reviews that depend on the exact technical wording of the parent reference
