Standard Values of Coefficients
The standard contains a number of coefficients, which can be adjusted in National annexes. The table provides description of individual coefficients, their values and corresponding artical 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.
