IEC 62011-2 Ed. 1.0 b – Insulating materials – Industrial, rigid, moulded, laminated tubes and rods of rectangular and hexagonal cross-section, based on thermosetting resins for electrical purposes – Part 2: Methods of test

Deals with the test methods for industrial, rigid, moulded, laminated tubes and rods of rectangular and hexagonal cross-section, based on thermosetting resins for electrical purposes. The test methods include the following:a) Dimensions – External dimensions – Internal dimensions – Wall thickness – Departure from straightness – Applicable to all tubes and rods b) Mechanical tests – Flexural strength perpendicular to laminations (rods only)– Axial compressive strength (tubes only)c) Electrical tests – General – Insulation resistance after immersion in water d) Other tests – Water absorption – Density
