Sampling for conformance inspection.
4.4.1 Lot. All material of the same type, grade, and thickness manufactured
under essentially the same conditions from the same batch of material and offered
for delivery at the same time shall be considered a lot for purposes of
inspection.
4.4.2 Sampling for visual and dimensional examination. A random sample of
sheets shall be selected from each lot offered for examination (see 6.2 and 6.7).
4.4.3 Sampling for tests. A random sample of sheets shall be selected from
each lot, except that only one sheet shall be selected from lots of 40 or under.
The random sample shall be subjected to the tests specified in 4.6 (see 6.2 and
6.7).
4.5
Conformance inspection.
4.5.1 Visual and dimensional examination. Each sample sheet selected in
accordance with 4.4.2 shall be subjected to visual and dimensional examination to
determine compliance with 3.2, 3.3 and 3.5. If any sheet in the sample contains
one or more defects, as defined in 3.5.1 and 3.5.2, it shall be rejected, and if
the number of rejected sheets in the sample exceeds the acceptance number for that
sample, this shall be cause for rejection of the lot represented by the sample.
The thickness shall be determined by the use of a suitable instrument, accurate to
0.001 inch. Five measurements shall be made at random points on the sheet.
