proportion conforming

[antonin]

Пожалуйста, помогите перевести "proportion conforming".

Выражение встречается в следующем контексте:
Conceptually, the Cp value compares the allowable process spread to the actual process spread. It can be thought of as indicating the potential of the process to produce conforming material. A common interpretation of Cp assumes that the process output is normally distributed. This interpretation leads to the oft quoted proportions conforming that are given in table 1.
