NBRISO

Could you clarify what NBRISO stands for or the domain it belongs to? It does not appear to have a single widely recognized meaning. For example, is it an acronym used in standards (such as Brazilian ABNT NBR ISO references), a chemical term, a company or organization name, or something else? Once you specify the intended meaning or field, I can generate a concise, neutral wiki-style article under 300 words.
