Standards
Above the curtain wall's foundations, one or more footing courses were laid. Offsets were introduced above these footing courses (on both the north and south faces), which reduced the wall's width. Where the width of the curtain wall is stated, it is in reference to the width above the offset. Two standards of offset have been identified. Standard A, where the offset occurs above the first footing course, and Standard B where the offset occurs after the third (or sometimes fourth) footing course.

Famous quotes containing the word standards:
“As long as our people quote English standards they dwarf their own proportions.”
—Ralph Waldo Emerson (1803–1882)
“Today so much rebellion is aimless and demoralizing precisely because children have no values to challenge. Teenage rebellion is a testing process in which young people try out various values in order to make them their own. But during those years of trial, error, embarrassment, a child needs family standards to fall back on, reliable habits of thought and feeling that provide security and protection.”
—Neil Kurshan (20th century)
“That’s the great danger of sectarian opinions, they always accept the formulas of past events as useful for the measurement of future events and they never are, if you have high standards of accuracy.”
—John Dos Passos (1896–1970)
