The yarn shall be 1/30 worsted count made from fleece, pulled sheep’s wool , or a combination of both, not lower in grade than 56’s US Standard, and cotton, blended so that the finished yarn contains not less than 50% wool on a dry weight basis. Core cotton yarn will be unacceptable. The merino yarn shall be twisted or plied with a nylon stretch yarn, using knitting twist.. The nylon yarn shall be 140 denier ~ 5 percent, 2 ply, stretch yarn. The top and leg portion above the high heel shall be knit using the merino blend yarn.

A double thickness of the terry portion (terry to terry) of the finished sock shall have a minimum thickness of 0.115 inches when tested according to Method 5030 of FED-STD-191. The presser foot shall be circular with a diameter of 0.375 + 0.001 inches and with the moving parts connected therewith w~ighted so as to apply a total load of nine pounds per square inch. TWO readings shall be taken on each of five specimens, the thickness of the sample unit shall be the average of ten results obtained from the specimens tested and shall be reported to the nearest 0.001 inch.

The finished sock shall be tested for felting shrinkage or elongation in foot length and leg length. At each of the specified locations, the felting shrinkage or elongation shall be not more than 6.0 percent when tested according to Method 7561 of FED-STD-191, except that in the felting silrinkage procedure, the period of laundering in the wash wheel shall be 2 hours.

Elongation shall be prefixed with a minus (-) sign.

The dyed Black socks shall show a minimum of Class 4 fastness to perspiration, a minimum of Class 3 fastness to laundering, and shall show an AATCC Chromatic Transference Scale rating for crocking not less than 1.5. The dyed Olive Green socks shall show a minimum of Class 4 fastness to perspiration and laundering, and shall shown an AATCC Chromatic Transference Scale rating for crocking not less than 3.5, when tested as specified according to AATCC Test Method 15 for Perspiration, AATCC Test Method 61 (Test No. 1A), for Launderingr and AATCC Test Method 8 for Crocking.

The stretch measurement shall be evaluated on a Houchin modification of a Schieffer machine described in test method 7540 of FED-STD-191. The sock shall be pulled over the form so that the 2 inch edges shall be parallel to the foot of the sock . The indicator pin shall be inserted in the upper 2 inch edge of the separating form and a 10 pound weight slowly applied so as to cause separation of upper and lower slotted form with resultant stretch of the sock under a uniform load over the 2 inch edges. The socks shall be evaluated after the weight has hung freely for 30 seconds and shall be expressed in 0.1 inches as the distance between the upper and lower edges of the separated form.

~/ The lengthwise stretch of the socks shall be measured using the sock measuring machine apparatus and measurement of specimen procedure specified in Method 7560 of FED-sTD-191.

The measurement shall be taken to the nearest 0.1 of an inch and the measured stretch “foot length” obtained in accordance with this procedure shall be considered as the lengthwise foot stretch.

Label/markinq. Each sock shall have a size marking and fiber content marking applied to it just below the instep and centered between the ankle and toe. The color of the marking shall be white. The size label shall be printed with characters a minimum of 5/16 inch in height and shall contain the sock size and the legend.
