Paragraph 3 Other gaps

Original text. Later amendments are not shown.

Any other gap in the structure of a bunk bed shall be measured by each of the following methods.

  • First, the point of the cone shall be inserted into the gap in such a way that its axis of symmetry is perpendicular to the plane which joins the boundaries of the gap. Without any axial force, and with at least two points of contact between the boundaries of the gap and the surface of the cone, such points of contact shall be on or between the 60 millimetre and 75 millimetre lines marked around the cone. The measurement shall be taken in as many places in any such gap as may be necessary to determine the most onerous condition of dimension of the boundaries of the gap.

  • Secondly, the point of the cone shall be inserted into the gap in such a way that its axis of symmetry is perpendicular to the plane which joins the boundaries of the gap. The cone shall be advanced slowly and steadily further into the gap until an axial force of 100 Newtons is indicated, in which condition the points of contact between the surface of the cone and the boundaries of the gap shall lie on or between the 60 millimetre and 75 millimetre lines marked round the cone. The measurement shall be taken in as many places in any such gap as may be necessary to determine the most onerous conditions of dimension and distortion of the boundaries of the gap.
