All,

The question was about the interprtation of the allowance to go to 40X to
verify a defect seen at 1.75X

Measurement oif the size of the defect has nothing to do with the higher
magnification allowance.  The spec. allows going up to 40X so that the
inspector may verify that his defect is really a defect.  Often at 1.75X
shadows at a nodule, small pits or roughness etc.may appear to be a defect,
but when a better viewing at up to 40X is used, it is found to be acceptable.
