The magnitude of loading which a joint has to sustain forms a critical element in the joint selection process. Any load in excess of the system design
load may cause the system to fail.
Loading considerations apply solely to floor-to-floor (and to a lesser extent to floor-to-wall) joints. All floor joints in the expansion joint system (EJS)
range are load capacity rated and this is expressed as either Pedestrian rated (P), High Pedestrian rated (HP), or as a vehicular load value expressed
in kiloNewtons (kN).
Vehicle loading values have been derived from two International Standards:

1. DIN 1055: Part 3: Loading of Fork Lift Trucks and Standard Vehicles
2. DIN 1072: Standard Moving Loads

DIN 1055 and DIN 1072 are recognised internationally as the most rigorous of their type and define loading magnitudes, vehicle types and wheel contact areas from which the load rating of expansion joint systems (EJS) are derived.

The following table is extracted from DIN 1055 and DIN 1072 and presents the varying types of vehicle, loads applied and wheel contact areas
which have been used in rating React Joints.
