1/ Sample size shall be 22 by 22 inches with 18 inch benchmarks, 6 inches apart.

2/ Use Drying procedure (D) or samples may be dried using a thermostatically controlled circulating oven 2210 -2300 F until dried. The sample shall be allowed to cool for 5 minutes, sprinkled with water to permit damp pressing, and allowed to stand in this condition for 5 minutes. The dampened specimen shall be pressed with a flatbed press or a hand iron. Section 7.4 of AATCC 96 shall not apply.

3/ When a color change equal to Step 4 on the Gray scale is evident in either sample being evaluated or the standard sample, exposure shall be continued for an additional number of hours equal to the number of hours at which the color change is apparent. Specimens which do not show a color change until 80 AFU's shall be returned to the machine for a total exposure period not to exceed 140 hours.

3.3.2 Thread. The thread for seaming and stitching shall be cotton covered polyester core, 2 ply, ticket No. 50, or a commercially equivalent thread with a minimum breaking strength of

3.2 pounds or ticket no. 70 with a minimum breaking strength of 2.6 pounds when tested in accordance with ASTM-D-2256. The color shall approximate the shade of the basic material, and shall show colorfastness to crocking, laundering, perspiration and light equal to the requirements and test methods for the basic material in Table I.

3.3.3 Elastic webbing. The webbing shall be made with a heat resistant rubber thread. The 1-1/2 inches wide webbing shall have a thickness range of .03 - .06 inches and a maximum weight of 1.2 oz. per linear yard when tested in accordance with ASTM-D-3776, option D.

The drift of the load on the webbing, elongated and maintained at 50% elongation using a 4 to

7.5 pound weight for 4 hours, shall be not more than 20% (the webbing is elongated to 50% of its total elongation, held in that position for 4 hours and the amount of change is recorded).

After the webbing has been elongated and maintained at 50% elongation for 10 minutes and then allowed to relax for 10 minutes, the webbing tension (change in length of the sample) shall be not more than 5%.

3.3.4 Slide fastener. The nonseparating, nonreversible, size 5-7 slide fastener without automatic pin or cam, shall be individual element molded plastic with a bridge top stop and bridge bottom stop. Pre-assembled or continuous chain application may be used. The color of the plastic components shall approximately match the basic material. The tape shall be 100% textured polyester. The length of the slide fastener shall fit the front opening shown on patterns. The color of the tape shall approximately match the basic material. The crosswise breaking strength of the chain shall be 110 pounds per minute when tested in accordance with ASTM D 2061. The fastener chain shall be tested for endurance meeting a minimum endurance of 1000 cycles when tested using a endurance testing machine such as a British Standard Reciprocator (BSR) or equal. The machine shall be set up with 3.5 lbs. lateral force and 3.1 lbs. longitudal force in accordance with ASTM D 2061.

3.4.2 Hook and pile fastener tape. The hook and pile fastener tape shall be a minimum of 1-inch wide, with a 6.5 mil nylon hook (220 denier) and nylon ground. The hook and pile tapes shall be stabilized as necessary to allow for maximum flatness and dimensional stability.

The color of the hook and pile fastener tape shall approximately match the basic material.

The fastener tape shall be stitched to the coverall according to the marks on the pattern 1/8 inch from the edge.

3.4 Labels. A commercial-type printed cloth label shall contain the contractors name, contract number, size and national stock number, (NSN), fiber and laundering information including “OR USE NAVEDTRA 414-01-4581 Formula II: Hot formula without bleach (140oF)”. The label shall be sewn on all four sides to the inside center back, below the collar.

3.4.1 Label/tag. A barcode label shall be attached to each item, and be clearly legible and readable by a scanner. The bar coding element shall be a 13 digit national stock number (NSN). The bar code type shall be a medium to high code density and shall be located so that it is completely visible on the item when it is folded and/or packaged as specified.

3.5 Patterns. The Government shall furnish a single size pattern. The contractor is responsible for grading patterns for additional sizes. However, a full set of patterns are available upon request. Commercial patterns may be used in lieu of government furnished patterns provided that they conform to the cited design and finished measurements. The standard pattern provides a seam allowance of 1/2 inch for shoulder seams, sleeve setting, inseams, crotch seams, side seams, pockets and flaps, and 3/8 inch for all other seams.

3.6 Finished measurements. The finished coveralls shall conform to measurements as shown in Table I. The coveralls shall be measured laying flat and smooth, with the front slide fastener completely closed. Tolerance for all measurements shall be 1/2 inch.
