BS 9124:2008 pdf free.Specification for steel and aluminium access cover systems with over 1 m clear opening.
Products under the scope of this British Standard are normally bespoke and so it is inappropriate for the evaluation of conformity to be verified by systematic examination of the extent to which they fulfil specified requirements. Therefore, although type tests are specified for all requirements, they fall into three categories.
1. Calculation in accordance with established method (e.g. structural performance).
2. Evaluation of a particular material or design element (e.g. slip/skid or sealing).
3. Measurement (e.g. design dimensions).
Some requirements (e.g. design dimensions) are absolute, in that every product needs to conform to the specified requirement.
This British Standard BS 9124 specifies requirements for access cover systems manufactured from steel or aluminium and with a clear opening greater than 1 m for installations within areas subject to pedestrian and/or slow moving vehicular traffic, for use as covers over chambers and ducts.
NOTE For clear openings up to 1 ifl, BS EN 124 applies.
BS 9124 establishes definitions; materials; design; structural performance; technical documentation; installation and operating guidance notes; warning notes; testing requirements; verification and marking of such access cover systems.
