Bob, You state: "Note that 60950 stability requirements are intended to address equipment which is not in motion." I disagree. Parag. 1.2.3.1 of the 60950 standard defines monable equipment as one that is either - 18 kg or less in mass and not fixed, or - equipment with wheels, castors, or other means to facilitate movement by the operator as required to perform its intended use. What I think you meant to say is that the stability requirements in 60950 should be revised by the international standards community to address tipping when they encounter floor joints, elevator thresholds, etc, a special concern when battery acids may be involved. All the Best,

It is inadequate to address moving carts. UL 1667 and UL 1678 are meant for that purpose. The first was in response to the deaths of children moving televisions in schools. Moving carts are prone to tipping when they encounter floor joints, elevator thresholds, etc, a special concern when battery acids may be involved.

My question is what standards will I need to test to for this. The power cart will be supplied with a battery charger, 12V lead-acid battery, and a 12Vdc to 120Vac or 12Vdc to 230Vac inverter. Thanks in advance for your help, Josh
