1 The lower and upper values for each dimension correspond respectively to the required average and minimum wall thicknesses. The average thickness may not be less than the stated value. Minimum values are permitted only in limited areas.
2 The lower and upper values for each dimension correspond respectively to the minimum and maximum tolerances.
Dimensions are expressed in millimeters.
