3.7 hazardous sharp point

A point which fails the appropriate test specified in Clause 6.7.

3.8 Mattress base

The surface on which the mattress is supported.

3.9 Side rail

A longitudinal component, fastened between a pair of structural uprights (e.g. corner posts) by which the mattress base may be

supported.

3.10 Structural uprights

Components to which other components such as the end and side rails are fastened to form a rigid structure. The structural uprights are intended to support the mass of the bunk bed and its contents (including the occupants).

NOTE: A common type of structural upright is the corner post as shown in Figure I.

3.11 Tread

A step or rung of a ladder or other structures designed for climbing.

4 MATERIALS

4.1 Timber

Timber used in bunk beds shall not contain splinters or loose knots and shall be free from deca and insect attack which would

affect its safe handling or structural integrity.

NOTE: It is recommended that the moisture content not exceed 13%. High moisture content can cause adhesive failure and excessive

shrinkage which would affect the structural integrity of the bunk.
