#tcfactsGlobally relevant standards
Expertise and consensus
Thousands of experts participate in IEC standardization work in IEC technical committees and subcommittees (TC/SCs). They are chosen by their National Committee (NC) to share their technical expertise and represent the national requirements of industry, government, test & research laboratories, academia or user groups at the global level in the IEC.
The IEC offers these experts a neutral and independent platform where they can discuss and agree on state-of-the-art technical solutions with global relevance and reach. These are published as voluntary, consensus-based international standards.
Each TC defines its scope and area of activity, which it submits to the IEC Standardization Management Board (SMB) for approval.
A TC can form one or more SCs depending on the extent of its work programme. Each SC defines its scope and reports directly to the parent TC.
The SMB also establishes project committees which prepare individual standards that don’t fall within the scope of an existing TC or SC. Project committees are disbanded once the standard has been published.
