scope:

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
