Hi Steve, I don't know what would apply in Europe. However, I can suggest taking a look at UL 1678<https://www.shopulstandards.com/ProductDetail.aspx?productId=UL1678>. It's intended to cover carts for audio/video equipment, but it does address potential hazards that might affect a products such as you are describing. It looks at both static and dynamic stability, including stability when being rolled over bumps, such as a door threshold, and over gaps, such as when exiting an elevator. UL 1678 considers issues such as handle strength, braking, and load strength.

It is on casters and when wheeled to the working location, leveling feet which are located in the center of the castor mount, are lowered and locked into position to keep the cart from moving and to ensure it is level. The product will be evaluated to EN 60204-1, but there is no reference to stability in this standard. First question is should EN 61010-1, 7.4, be used to evaluate stability, and if not then what? Assuming yes, the first sentence of 7.4 says; 'Equipment and assemblies of equipment not secured to the building structure before operation should be physically stable.' Second question is does this section apply to the cart only when in position for use, or also when being moved from location to location? Because when in use the cart is supported by [properly rated] feet, then the tests for castors should no longer apply?. That is the third question. Your thoughts and comments are requested and appreciated, as always.
