4.3.2 Tests of End ltems. Each lot of file folder of the same type, class, style, and grade; produced at essentially the same time and conditions shall be tested for the characteristics, and in accordance with the referenced test methods in Table lllA. The sample unit shall be one file folder. Sample using level S-

1, AQL 2.5% defective, for each test.

4.4 Test Methods

4.4.1 Writing Quality. Draw five 6 inch lines, and write ten 5 letter words or phrases on the front leaf of one folder from a sample unit, with a smooth point dip pen using a 1 percent aqueous solution of red or green writing or drawing ink which will accentuate feathering. Observe the lines and characters for clarity and feathering. To be considered satisfactory, there shall be no feathering of lines, or characters which are unclear.

4.4.2 Tests for Gusset Materials

4.4.2.1 Cloth Gussets

4.4.2.1.1 Tearing Strength of Cloth. This test shall be performed in accordance with ASTM D 1424 except that the specimen shall be prepared as follows: Cut a rectangle 2-1/2 inches by 4 inches from a Grade A folder, including the cloth gusset and, as necessary, an equal portion of each leaf. The 4 inch direction of the specimen shall be along the horizontal dimension of the folder. Select that portion of the gusset that does not include the overlap. Use the Elmendorf tear tester, without augmenting weight, and follow the procedure of the referenced method. The results shall be shown as a direct reading of the scale units.

4.4.2.2. Spunbonded Polyolefin

4.4.2.2.1 Tearing Strength of Spunbonded Polyolefin. The spunbonded polyolefin shall have an Elmendorf tearing strength of not less than 400 grams in the long direction when tested in accordance with ASTM D 1922. Sample shall be prepared as specified in 4.4.2.1.1.

4.4.2.2.2. Fold Endurance Spunbonded Polyolefin. The spunbonded polyolefin gusset shall have a fold endurance of not less than 5,000 folds when tested in accordance with ASTM D 2176.
