4.4.2 Straightness. Straightness shall be determined by placing the
piece or sample unit on a level surface. Place a straight edge one foot
in length parallel to the length of the sample so that it touches the edge
being tested and extends an equal distance on both sides of the point of
apparent maximum deviation. Measure with a steel scale graduated to 1/100
of an inch the perpendicular distance from the straight edge to the edge
of the test sample at the point of maximum deviation from straightness.
4.4.3 Preparation for shipment. Examination of the packaging and
packing, and marking for shipment shall be made for conformance with the
requirement of section 5.
