Portuguese to English Marketing Marketing customer satisfaction survey from a gas supplier

Hi,

I was wondering if anyone knows what this abbreviation stands for?

It comes from a customer satisfaction survey for a gas supplier.

It is from Brazil to be translated into UK English.

The question asked was "Finally, do you have any additional comments to make regarding your experience with [company]?"

The full answer was "Toda instalação deveria ser acompanhada de uma ART."

Is it something to do with risk assessment?

Many thanks for your help.
