  • The minimum outside diameter of a single tube column must be 63 mm. For a telescopic double tube column, the outside diameter of the inner tube must be 63 mm and the outer tube must be 70 mm. The outside diameter of the columns must not be greater than 89 mm to permit their use in 51 x 100‑mm frame-constructed walls (plane-finished dimension).
  • Three columns shall be selected at random for testing and the maximum allowable working load capacity must be at least 36 kN with a safety factor of 2.25.
