Q: Is this unit ul tested, if yes, to what standard. if not, what standards has it been tested?

UL 507 is the relevant standard for electric fans, however this fan was not tested by UL. Also important to note that UL Listed products are tested while UL Recognized products are not tested. Both levels require a direct marking on the part which means this fan has neither level. To be honest most fans at this price level are not going to be agency tested just because the target market is PC case fans, and the things UL tests for are not relevant to PC builders. The fan has CE certification which is just saying it won't burn your house down. CE doesn't check fans for performance; you're better off reading reviews than looking for agency approvals if this is a PC fan.

Q: will this fan work with just pos & neg hooked up? do I need all for wires hooked up to work ? thanks

Will work with just pos and neg.

Q: If I plan to use more than 50% capacity of the 5300rpm model, would I need to connect it to a controller/hub rated for more than 1amp per lane?

I would make sure that which ever Fan Port you connect this High Airflow Fan that it will support the amperage stated in the specs of the fan.

Q: Any water or dust resistance rating? ip52, ip67?

I do not see any water/dust proof rating printed, however, I use this fan as a range-top exhaust fan in suction mode, so all cooking steam & grease-laden fumes are drawn across/through the fan... daily. Thus far, it has performed flawlessly, despite the harsh environment. I recommend this fan.
