5 Sampling

5.1 A minimum of three rolls is to be ran-

domIy drawn from each shipment of tape The

following tests are to be made on lengths cut

from each roll

6 Test Methods

6.1 Yards Per Pound:

6.1.1 Determine the yards per pound of

tape as directed in Methods D 1910

6.1.2 For each shipment, make a minimum

of three determinations on specimens, each of

which has been taken from a different roll

The average of these three determinations

shall be considered the average weight of the

shipment involved

6.2 Width:

6.2.1 Determine the width of the tape as

directed in Methods D 1910

6.2.2 Make at least ten measurements of

width from each roll selected and record the

average and the range of width

6.3 Thickness:

6.3.1 Determine the thickness of the tape

as directed in Method D 1777

6.3.2 Make at least ten measurements of

thickness from each roll and record the aver-

age and the range of thickness

6.4 Construction:

6.4.1 Ends-Determine the total number

of ends for the full width of tape as directed in

Methods D 1910

6.4.2 Picks -Determine the number of

picks as directed in Methods D 1910

6.4.3 Nimber of Tests:

6.4.3.1 Ends-Make one determination of

total warp ends from each roll selected and

record

6.4.3.2 Picks -Make three determinations

of picks per inch from different places from

each selected roll Average all results and

record

6.5 Breqking Strength:

D 259

6.5.1 Determine the breaking strength of the tape on a tensile testing machine conform- ing to Specification D 76 Discard results from specimens that break in the clamps of the testing machine

6.5.2 Test the specimens in the warp direc- tion by the strip method (full width) as di- rected in Method D 1682 The initial distance between the clamps shall be 3 in (75 mm) 6.5.3 Test the specimens in the direction of the filling by the grab method as directed in Method D 1682 The initial distance between the clamps shall be I/s in (3 mm)

6.5.4 Make at least five determinations of the warp and filling breaking strength from each roll selected T h e average of al1 tests for each direction shalI be considered the strength

of the lot

6.6 Nonfibrous Materials:

6.6.1 Determine the total amount of nonfi- brous materials as directed in Section 8 of Method D 629 Perform the test on a com- posite sample of approximately 5 g

6.6.2 Make at least one determination of nonfibrous material content from each roll selected The average of these determinations shall be considered the amount of nonfibrous materials for the lot

7 Conformance

7.1 The purchaser and the supplier may agree on a procediire to establish conform- ance, including control charts furnished by the supplier, a sequential sampling plan, or the double sampling plan outlined in 7.2 7.2 In the absence of a control chart or sequential sampling plan, proceed as directed

in 7.2.1 through 7.2.3

7.2.1 If the test results for the lot conform

to the tolerances for all characteristics speci- fied in Section 4, consider the lot a valid delivery

7.2.2 If the test results for one or more

characteristics do not conform to the toler-

ances, take a new laboratory sample from

either the original lot sample or a new lot

sample Retest the lot for the characteristic(s)

that did not conform to the tolerances in the

first test, and average the results of the first

and second samples as if the results were from

one test of double the original number of specimens If the new average(s) conform(s)

to the specified tolerances, consider the lot a

7.2.3 If the test results obtained as directed

in 7.2.2 do not conform to the specified toler- ances, consider the lot a nonvalid delivery
