Historically Important Standards
Standards became highly important during the Industrial Revolution with the need to make interchangeable parts. Some important historical standards included:
- Sizes for screws, nuts bolts and other threaded fasteners were first standardized based on work of by Joseph Whitworth. This was known as British Standard Whitworth, but was replaced by other standards in the late 19th century.
- Railroad track gauge was standardized so that rail cars and locomotives could operate on track of various railroad companies. Before standardization it was necessary to unload and reload freight at every change of gauge.
- Pipe sizes
- Shoe size standardization was made easier by the Blanchard pattern lathe which could make nearly identical copies of the wood lasts on which the shoes were held and shaped. Standard lasts enabled a manufacturer to make standard shoe sizes.
- The screw base size and thread dimensions of electric lamp bulbs was standardized by Thomas Edison.
- Electrical voltage and frequency
- Electrical wiring and device standards

Famous quotes containing the words historically, important and/or standards:
“It is absolutely impossible to transcend the laws of nature. What can change in historically different circumstances is only the form in which these laws expose themselves.”
—Karl Marx (1818–1883)
“The last publicized center of American writing was Manhattan. Its writers became known as the New York Intellectuals. With important connections to publishing, and universities, with access to the major book reviews, they were able to pose as the vanguard of American culture when they were so obsessed with the two Joes—McCarthy and Stalin—that they were to produce only two artists, Saul Bellow and Philip Roth, who left town.”
—Ishmael Reed (b. 1938)
“Measured by any standard known to science—by horse-power, calories, volts, mass in any shape,—the tension and vibration and volume and so-called progression of society were full a thousand times greater in 1900 than in 1800;Mthe force had doubled ten times over, and the speed, when measured by electrical standards as in telegraphy, approached infinity, and had annihilated both space and time. No law of material movement applied to it.”
—Henry Brooks Adams (1838–1918)
