Behind the Standard: How IEC, ISO and CISPR Develop the Standards We Use

Every standard like the EMC standard have travelled a long journey before it reaches the test bench. Although these documents look simple on paper, IEC, ISO and CISPR standards come from structured global processes that bring many voices together and ultimately shape how EMC testing solutions are designed and used.

The work often starts at the national level. Each country has a national committee that studies new topics and reviews existing standards. These groups include manufacturers, labs, regulators, and academics. Their discussions shape the national position. After that, the national mirror committee selects delegates and experts. These specialists represent their country in the IEC, ISO or CISPR technical committees, where the real development begins.

The process typically follows a 33-month target timeline, although the actual duration can vary depending on the complexity of the work and committee decisions. First, a proposal defines the need for a new standard or revision. Then members vote on the idea and commit resources. When approved, experts start drafting the technical content. They exchange data, run experiments, and settle wording. Later, the draft goes out for a vote and public comments. Committees study this feedback and refine the text. A final vote then confirms the document and sends it toward publication. As a result, each standard reflects both technical depth and international agreement.

The work does not stop after publication. After publication, the responsible committee assigns a stability or maintenance review date, which determines when the standard will be evaluated for confirmation, revision or withdrawal. At that point, committees must decide what happens next. They can withdraw the standard if it is no longer relevant. They can keep it unchanged if the content still fits industry needs. Or they can start a revision or amendment when new technologies or field issues require updates.

This ongoing cycle ensures that IEC, ISO and CISPR standards stay aligned with real-world challenges. It also gives engineers a reliable foundation that evolves as fast as the technology they design.

Yet the process offers more than rules on paper. It creates a global framework built on shared responsibility, technical knowledge, and cooperation. When each nation contributes its expertise, the result is a standard that serves the entire industry, not just one market or technology.

Understanding how these decisions are made helps engineers read standards with greater confidence. It also shows why active participation matters. When companies, labs, and experts join the conversation, the standards become clearer, more practical, and better suited for the future of EMC.
