Examination for weight and winding. The sample unit for this examination shall be one tube or spool
of twine. For lots consisting of 500 or fewer units, the sample size (number of sample units) shall be 10. The
inspection level shall be S-3 and the AQL shall be 4.0 percent defective. The lot size shall be the number of tubes
or spools of twine in the inspection lot. Defects shall be as listed in 4.2.3.1 and 4.2.3.2.
4.2.3.1
Examination for weight. A defects with regard to weight shall be considered to exist if the net weight
of a tube or spool is less than the minimum or more than the maximum specified in 3.7. The number of holders
examined shall be utilized in determining the average weight. A lot shall be unacceptable if the average weight is
less than the 1 pound weight specified in 3.7.
4.2.3.2
Examination for winding. Defects with regard to winding shall be considered to exist if any of the
following are determined during inspection.
(a) Improperly or not firmly wound resulting in kinking, knotting, entangling or slippage during
unwinding, or otherwise affecting free unhampered unwinding of twine.
(b) Any length of twine less than 16 yards on a tube or spool.
(c) A total of three or more knots or laid-on ends on a tube or spool.
Testing of the end item. The methods of testing specified in FED-STD-191, wherever applicable and
4.2.4
as listed in table V shall be followed. When the data in the "number of determinations" and "Results reported as"
columns are not specified in the table, they shall be as required by the referenced test method. The physical and
chemical values specified in section 3 apply to the average of the determinations made on a sample unit for test
purposes as specified in the applicable test methods. The sample size shall be in accordance with table IV. The
sample unit for testing shall be one tube or spool of twine. The lot size shall be expressed in units of one tube or
spool. All test reports shall contain the individual values utilized in expressing the final result. The lot shall be
unacceptable if one or more units fail to meet any requirement. Tests to determine compliance with specification
requirements, including quantity of delivery, may be made under prevailing atmospheric conditions. In cases of
dispute, tests shall be made upon material which has reached equilibrium under Standard Conditions as defined in
FED-STD-191.
