This part of IEC 61212-3 gives requirements for industrial rigid round laminated rolled 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 standard alone. It is the responsibility of the user of the methods contained or referred to in this document to ensure that they are used in a safe manner. The responsible committee is DKE/K 181 "Feste elektrische Isolierstoffe" ("Solid electrical insulating materials") of the DKE (German Commission for Electrical, Electronic and Information Technologies) at DIN and VDE.
