How should turntable load capacity be evaluated when buying a rotating clay-pot cooker?

To judge turntable load capacity on a rotary claypot rice cooker, add up real per-batch weights: claypot, rice and water, plus toppings such as preserved sausage or ribs, then layer on the turntable's own mass and the off-centre force created while spinning. A static pass proves little once rotation starts. Run two loaded rounds, one evenly filled and one deliberately weighted to a single side, watching for sagging, unusual noise, edge wobble, and any change in the gap between pot base and burner row. Ask the maker to perform this with actual claypots before dispatch, logging each load, the offset position and observed behaviour, so incoming inspection can repeat the same trial and later changes in pot size or batch weight remain verifiable.
