What is ISO 22915-21 about?  
ISO 22915-21 specifies the tests for verifying the stability of order picking trucks with an elevating operator position, where the operator's position can be raised to an elevation above 1200 mm.
Note: It is not applicable to trucks fitted with a load carrier that can be shifted laterally or pivoted out of the truck's longitudinal center plane.

What’s changed since the last update? 
ISO 22915-21:2019 supersedes ISO 22915-21:2009, which has been technically revised.
The main changes compared to the ISO 22915-21:2009 are as follows:
- An additional stability test for creep speed is added
- The explanatory note to the maximum travel speed is adapted to the state of the art
- Several drawings are redrawn for better comprehensibility
