Standard Values of Coefficients
The standard contains a number of coefficients, which can be adjusted in National annexes. The table provides a description of individual coefficients, their values, and corresponding article of the standard. In some cases the formula contains a variable, which has no symbol in the standard - in such a case the variable in the expression is denoted by X.
