I don't think “questions about CS-related standards” is a useful classification. Some questions involving standards are on-topic, others are off-topic. The question you cite is a bad question for other reasons (the answer is found in the obvious Wikipedia article); even then it wouldn't be a science question, because it's a pure matter of convention. There can be scientific questions about standards; asking why a standard did things the way it did is often on-topic, in that it calls for an analysis of what the possible choices were and what trade-offs mattered. Asking about the behavior of specific implementations of a standard is generally a technological question and not a scientific question; this can venture into science as well, if you're studying compliance or the robustness of the standard, but factual questions about standards are generally best answered by the practitioners who implement them rather than the scientists who make the underlying theoretical designs and experimental studies.
