The same specimens used in the thermal shock test shall be used.
16/
Finished material from a fiber sample.
4.6.1 Inspection of product for delivery. Inspection of product for delivery shall consist of group A
inspection.
4.6.1.1 Unit of product. A unit of product shall be 1100 meters minimum.
4.6.1.2 Production unit. The production unit shall consist of the number of units of product produced
on the same production line or lines, and offered for inspection at one time. All of the units of product in
the production unit submitted shall have been produced during the same production period with the same
materials and processes.
4.6.1.3 Specimen. A specimen shall be an individual length of fiber cut from the sample. Unless
otherwise specified, a minimum of the specimens shall be inspected and tested from each sample.
4.6.2 Group A inspection. Group A inspection shall consist of the inspections and tests specified in
table II.
4.6.2.1 Sampling plan. Group A inspection shall be performed on 100 percent of delivered product.
4.6.2.2 Disposition of sample units. Sample units from which a specimen has failed any of the group A
