Is it from someone flying two flags (standards are a type of banners or flag) and say riding both sides of the fence? I'm guessing here as I can find nothing on this. but it sounds logical to me.

'Double standard' as two equivalent standards
The earliest matches for "double standard" in a Google Books search across the years 1800–1900 relate to currencies based on both gold and silver. For example, The Opinions of Sir Robert Peel, Expressed in Parliament and in Public, Second Edition (1850) includes these consecutive excerpts on the topic of "A Joint Gold and Silver Standard":
Mentions of a "double standard" in connection with bimetallism occur as early as March 19, 1821, and continue until as late as 1900, the last year of the search period I used. The term also comes up in connection with corn gauged by weight and measure (1834), with sugar gauged by grain and whiteness (1834), with duty to "the Charter and the King" (1843), with obedience to "the Book of Scripture ... and the Book of Nature" (1848), with Iceland's old double monetary valuation standard of wadmal (wool) and silver (1874), and with milk gauged by solids and fat (1896).
The essential feature of bimetallism is that it attempts to establish a constant ratio of equivalence between gold and silver, so that both metals have a consistent relative value and are, in that sense, interchangeable—just as, in the United States today, four metal quarters and a paper one-dollar bill are interchangeable (or exchangeable). So the double standard doesn't imply that one standard unfairly benefits the metal to which it applies at the expense of the metal subject to the other standard, but that the two standards are in balance and are fair to both metals.
One of the more interesting abstract uses of the term double standard arises in "Origin, Nature and History of Oaths," a review of James Tyler, Oaths, Their Origin, Nature and History, in The Law Magazine (November 1834):
Here again, the point is not that the two standards put witnesses to very different levels of obligation (although that is clearly the implicit logic of the pro-oath movement), but that morally they are equivalent and entail the same level of obligation and, therefore, that the second standard—requiring witnesses to swear an oath—is unnecessary.
Not terribly surprisingly, the entry for double-standard in Charles Morris, The American Dictionary and Cyclopedia, Volume 4 (1900) refers exclusively to bimetallism:
'Double standard' as separate and unequal standards
One of the earliest instances of double standard in the sense of separate and unequal systems of appraising human conduct turned up in a Google Books search appears in Frances Harper, "A Double Standard" (1895), a poem that focuses on the severe imbalance in the standards by which society judges a woman and a man involved in a love affair. The poem concludes with this quatrain:
Another early instance of double standard in connection with separate and unequal standards for men and women appears in Newton Riddell, A Child of Light: Or, Heredity and Prenatal Culture Considered in the Light of the New Psychology (1900), who devotes an entire chapter to "Heredity and the Double Standard":
Riddell goes on to explain that the fundamental element of the "double standard" he has in mind involves social attitudes toward chastity.
The Wikipedia article quoted in Josh61's answer cites an even earlier instance of the use of double standard with regard to morality. From a review of Josephine Butler, "The Unjust Judgments Prevalent in Society, on Subjects of Morality," in The Ecclesiastical Observer (May 1, 1872):
Perhaps the most striking aspect of double standard as used by Butler, Harper, and Riddell is that the doubleness that the term refers to is grossly and brazenly unequal, whereas proponents of previous varieties of double standards sought emphasize the equivalence of the alternative measures offered as dual standards.
Butler, Harper, and Riddell notwithstanding, double standard in the sense of applying unequal criteria to assess the same behavior or work didn't appear in a Merriam-Webster Collegiate Dictionary until the Seventh Edition (1963):
