Once a standard has been defined, it must be assigned to a standard "class." This is a
group of from one to seven standards that is required to calibrate for a single error term.
The standards within a single class can be assigned to the locations listed in Table 7-2
according to their standard reference numbers.
A class often consists of a single standard, but may be composed of more than one standard
if band-limited standards are used. For example, if there were two load standards—a fixed
load for low frequencies, and a sliding load for high frequencies—then that class would
have two standards.
