c. End item inspections (see 4.4.1)

4.2 First article inspection. A first article, submitted in accordance with 3.1.1, shall be inspected, examined for appearance, color and finished defects as specified in 4.4, 4.5, 4.6 and Table IV and tested for the characteristics as specified in Tables I, II and III.

4.3 Conformance inspection. Conformance inspection (see 3.1.2) shall include the examination of 4.4 and the tests of 4.4 through 4.7 as applicable.

4.4.1 In-process examination. Visual and dimensional examinations shall be made at any point or during any phase of the manufacturing process to determine whether construction details which cannot be examined in the finished product are in accordance with the requirements specified in Section 3. Any in-process nonconformance remaining in the finished socks shall be classified as a defect in accordance with this document.

4.4.2 Components and material examinations and tests.

2/ The organisms used for testing shall be Staphylococcus aureus ATCC 6538 and Pseudomonas aeruginosa ATCC 9027. Samples shall be taken from the foot section of the sock. Antimicrobial testing shall be conducted on an annual basis.

3/ AATCC-100 shall be modified as follows:

a) Grow test organisms Staphylococcus aureus ATCC 6538 and Pseudomonas aeruginosa ATCC 9027 in 1x nutrient broth (NB) overnight.

b) Determine Optical Density at 600 nm (OD600). Dilute with 1x NB to OD600 = 1, yielding a cell concentration of approximately 108 CFU/ml.

c) Spin out cells 3 minutes at 10,000g and remove supernatant. Wash 1 ml cells with 1 ml 0.125x (diluted 1:8) NB medium with 0.15 % (w/v) Triton X-100. Repeat spin and wash 2nd time. Re-suspend cells in 1 ml 0.125x NB/0.15% Triton. Recheck OD600.

d) Dilute cells 1:10 with 0.125x NB/ 0.15 % (w/v) Triton X-100 to target concentration of 1-2x107 CFU/ml. Serially dilute inoculum 10-fold for plating to determine concentration.

e) For a single determination for each organism, two incubation times, 0, and 24 hour, shall be examined. Cut each specimen into 48 mm circles in triplicate for each time point. Do not sterilize; plating will be done on medium selective for the test organisms (see step k).

f) Inoculate each single swatch specimen in a petri dish with the amount a single swatch specimen can absorb within 10 - 20 minutes. Avoid puddling of inoculum not in contact with the sample.

g) For 0 and 24 h swatches, place the rolled swatch into a sterile 100 ml bottle and cap.

Swatch rolled with tweezers when inserting into the bottle will minimize contaminating the neck with the organisms on the swatch (purpose is to reduce or prevent inoculum not in contact with the swatch).

h) Process 0 hour contact time immediately. Incubate 24 hour inoculated swatch at 37

(± 2oC).

i) Add Dey-Engley (D-E) broth to each of the replicates before doing 10-fold dilutions.

Add D-E at 100 times the swatch inoculum volume (e.g., for an inoculation volume of 0.2 ml, neutralize with 20 ml D-E; dilution is 10-2). Shake bottles 1 minute.

j) Serially dilute D-E solution as needed 10-fold in PBS buffer to obtain valid counts.

k) For manual plating, spread plate 0.1 ml of the 10-3, 10-4, 10-5 dilutions in duplicate on selective media. For spiral plating, plate 0.05 ml of 10-3, 10-4 dilutions in duplicate on selective media.

These dilutions are usually suitable to obtain valid counts.

i. S. aureus – BBL Mannitol salts agar (cat # 211407, BD Diagnostic Systems)

ii. P. aeruginosa – Cetrimide agar (cat # 7222, Neogen Corp)

l) Incubate plates overnight at 37 (±2oC).

m) Report the bacterial concentrations (CFU/ml) for each swatch at both contact times.

Use average triplicate concentration for 0 and 24 hour contact times to calculate percent reduction for the treated swatches and untreated control. Also report starting inoculum concentration; minimum valid concentration is 5x106 CFU/ml. Untreated control would not be expected to exhibit reduction.

4/ Laundering and drying conditions using AATCC-150, Table I, (3), (IV), (A), iii.

5/ Rated using the AATCC Evaluation Procedure 1, Gray Scale for Color Change 6/ Rated using the AATCC Evaluation Procedure 2, Gray Scale for Staining.

7/ Using 10 steel balls and three (3) laundering cycles with drying after each cycle. Only the stain on the nylon and cotton fibers of the color transfer cloth shall be evaluated.

8/ Rated using the AATCC Evaluation Procedure 8, AATCC 9-Step Chromatic Transference Scale 9/ Condition socks for a minimum of four (4) hours at 70 (± 2°) F and 65 (± 2) percent (%) Relative Humidity before weighing.

10/ Per 12 pair, oz., minimum, (to the nearest 1.0 oz.)

4.6 End item examination. Each pair of socks selected for end item examination shall be examined for shade, design, material components, construction and workmanship. All defects shall be scored in accordance with Table IV. Material defects are defined in Section 1 of FED- STD-4 and shall be scored when observed at a distance of 3 feet or more. The finished examination sample size, acceptance quality limits and acceptance criteria shall be specified in the solicitation or contract (see 6.2).

4.6.1 Visual examination. The socks shall be examined for the defects listed in Table IV.
