Provides background and explanatory material to the requirements of the Standard. It also provides advice and guidance in certain areas which cannot at this stage be covered by the Standard.

The Standard specifically limits its application to the design of adjustable static pallet racking (in permissible stress method) made of cold-formed or hot-rolled members. The Standard does not cover materials other than steel.It is the intention of the Standard to cover such racking commonly referred to as 'adjustable pallet racking' and 'stacker' racking (both 'open' and 'closed' faced) and 'shelf' and other racking, all of which are static.Other commonly known racking such as 'drive-in' and 'drive-through' racking, cantilever and mobile racking are excluded from the Standard. Due to their nature and special requirements for stability and effective length criteria, these types of racking are not addressed by the Standard.
