IEC 61212-3-2:2013 gives requirements for industrial rigid round laminated moulded tubes for electrical purposes, based on different resins and different reinforcements. Applications and distinguishing properties are given in Table 1. Materials which conform to this specification meet established levels of performance. However, the selection of a material by a user for a specific application should be based on the actual requirements necessary for adequate performance in that application and not based on this specification alone. This third edition cancels and replaces the second edition published in 2006. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition: Details of test for insulation resistance after immersion in water are changed. Key words: industrial rigid round laminated moulded tubes
