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 rodsb) Mechanical tests- Flexural strength perpendicular to laminations (rods only) - Axial compressive strength (tubes only) c) Electrical tests- General- Insulation resistance after immersion in waterd) Other tests- Water absorption- Density
