If there are dated references in clause 2 of 61326, they should be updated to refer to the latest versions, regardless of whether that makes a difference or not. However, updating is essential only if there IS a difference. Note that this applies to 61326 as a product EMC standard. For other types of standard, the relation between dated references and update requirements may be different. This is a developing subject within IEC. -- OOO - Own Opinions Only.
