Simply put - standards are an agreed-upon way of doing something.
Industry standards are used by producers of goods and services. They specify how an item should be made by providing exact measurements and specifications about the materials. One example of a standardized product is the light bulb. No matter what brand you purchase in the U.S., the screw threads of the light bulb will probably fit your lamp (if it was also manufactured in the U.S.). European standards are often different - so a lamp made in Europe would probably need a different light bulb than those in the United States. Standards ensure that there is consistency and uniformity in items being produced.

As late as 1927, GREEN lights meant STOP in some U.S. cities and GO in others. There were frequent traffic accidents when travellers visited other cities.
A fire broke out in 1904 in Baltimore, Maryland. Special trains rushed fire equipment from Washington, New York, and Philadelphia. The fire destroyed approximately 2,500 buildings and burned for more than 30 hours...all because the hoses from the other cities would not fit the Baltimore hydrants.
