I know this is an old thread but the phrase "bog standard" means something ordinary, commonplace and unremarkable - years ago some program was going through the history of household inventions and it said that the phrase came about because of the name of the firm which all but had a monopoly on making toilet bowls, such that almost every toilet in the country was a Bog Standard toilet bowl. Even today in the uk a common slang word for a toilet is "a bog". It claimed that the phrase "box standard" was a corruption and slight change of meaning by those who preferred not to use a phrase referring to toilets.
