The difference between the reading taken upon the application of a maximum load () and the reading observed within and after 30 minutes of exposure of 90 % to 100 % of shall not exceed 0.7 times the absolute value of MPE for the applied load.

Regardless of any value declared by the manufacturer for the apportioning factor, , the MPE for creep shall be determined from using the apportioning factor, .

The difference in readings taken after 20 minutes of exposure to 90 % to 100 % of and at 30 minutes of exposure to 90 % to 100 % of shall not exceed 0.15 times the absolute value of MPE.
