Platform Level Force
If the force from the cargo on a mounted pole applies just above the level of the loading platform (maximum 0.2m height), this force is called a platform level force. The applied force can be a distribute force, a point load or a mixture of both.
Pole
A straight or curved profile mounted on the loading platform of a vehicle – either com- pletely fixed or mounted in such a way that it can be easily dismounted – designed and built to restrain sliding and tilting of cargo. The profile can be reinforced in the zone of its mounting on the platform or even in the zone above. A pole is not connected to the roof nor to the walls of the vehicle.
Portable detection system

R
Reference Bloking Capacity
The maximum force a specific mounted pole can resist to, depends on the height of the point of application of the forces on the pole. The reference blocking capacity RBC is the maximum horizontal static force a pole and its mounting on the vehicle can resist to without any permanent deformation, assumed that the force is uniformly distributed over a height of 1m starting from the loading platform upwards. This means that a point load of RBC can be applied at a height of 0.5m as far as no local deformation occurs. The blocking capacity is always specified for a certain direction and a certain sense (e.g. straight forward, e.g. transverse outward).
Rigidity
The load unit is rigid under specific acceleration in a given direction if the deformation and relative movements of parts of a test load unit of that type are less than the acceptable u limits as defined in this standard. Depending on the dimensions and the position of the center of gravity, a rigid type of load unit might tilt under the specified acceleration.
