1/ Visual shade matching. The color and appearance of the finished cloth shall match the standard sample when viewed using AATCC Evaluation Procedure 9, with source simulating artificial daylight D75 illuminant with a color temperature of 7500 (+ 200)◦K illumination of 100 (+ 20) foot candles, and shall be a good match to the standard sample under incandescent lamplight at 2856 (+ 200)◦K, when tested as specified in 3.5.1.

2/ Machine cycle, permanent press; Wash temperature, 120 (±5)◦F; Tumble Dry, permanent press.

3/ Wicking Test Procedure. The wicking test procedure is used to determine the rate at which water will wick on test specimens suspended in water.

Apparatus

- Flask. A 500 ml Erlenmeyer flask shall be used.

- Straight Pins. Straight pins approximately 3 inches in length shall be used.

- Food Coloring. A food color shall be used that will be visible on the specimen to indicate the water level during testing.

Testing Procedure A sample size of 6 inches by 1 inch will be cut with the 6 inches cut measured in the Wale direction. A 500 ml Erlenmeyer flask shall be filled with 200 ml of colored water (food coloring used shall be a contrasting color to the cloth material to make the water level visible on the sample) NOTE: Fill as many flasks as specimens to be tested. The top edge of the sample will be pierced with a long straight pin (approximately 1/8 inch to 1/4 inch from top) and the sample then suspended from the top of the flask as shown in Figure 1.

After 15 minutes, remove the sample from the flask and measure water level on sample in inches and record. Values are reported as inches per minute.

3.5 Color. The color of the washcloth shall be Brown 436 and shall match the standard sample

(see 6.2).

3.5.1 Visual shade matching. The color and appearance of the finished washcloth shall match the standard sample when tested as specified in 3.4.1.

3.6 Dimensional stability. The finished washcloth shall not shrink or elongate more than 4.0 percent in either the warp or filling direction after 5 complete cycles when tested as specified in

3.4.1.

3.7 Wicking. The wicking rate of the finished washcloth shall meet a requirement of 6 inches in a 20 minute time period when tested as specified in 3.4.1.

3.8 Dynamic absorption. The finished washcloth shall show a rating of 75 for initial and 73 after 5 launderings when tested as specified in 3.4.1.

3.9 Soil release finish. The soil release finish of the washcloth shall show a rating of not less than “4” using the AATCC Stain Release Replica, when tested as specified in 3.4.1.

3.10 Labels. The label shall be a white, nonwoven, spun bonded polyester cloth or nonwoven mildew-resistant printed, acrylic coated, impregnated, 80/20 polyester/cellulose cloth, located on one of the outside edges of the washcloth, sewn into the binding on the edge. The label shall be

Laundering instructions

1. Wash with moderately hot water (115°F) using soap or mild detergent.

a. For machine washing. Use permanent press cycle.

b. For hand washing. Do not wring or twist.

4. VERIFICATION

4.1 Classification of inspection. The inspection requirements specified herein are classified as follows:

a. First article inspection (see 4.2).

b. Conformance inspection (see 4.3).

4.2 First article inspection. The first article, submitted in accordance with 3.1, shall be inspected for compliance with design, workmanship and dimensional requirements. The presence of excessive defects, as defined by contract (see 6.2) or failure to pass any test shall be cause for rejection of the first article. The sample size shall be specified in the procurement document (see

6.2). The sample unit shall be one (1) washcloth and the lot size shall be expressed in washcloths.

4.3 Conformance inspection. Conformance inspection shall include shade and appearance of all components, finished measurements and defects specified in Table III. Sampling for inspection shall be performed in accordance with ANSI/ASQ Z1.4, as defined in the contract (see 6.2), except where otherwise indicated. The sample unit shall be one (1) washcloth and the lot size shall be expressed in units of washcloths.

4.4 Inspection conditions. In accordance with 4.1, components and end items shall be tested in accordance with all the requirements of referenced documents unless otherwise excluded, amended, modified, or qualified in this document or applicable procurement documents (see 6.2). The

Government reserves the right to inspect all components and end items to determine conformance to requirements.

4.4.1 End item visual examination. The washcloth shall be examined for the defects listed in

Table III. The lot size shall be expressed in units of washcloths. All cloth and washcloth defects shall be scored in accordance with Table III, which are clearly noticeable at normal viewing and affect serviceability and appearance of the washcloth. Material defects are defined in Section 1 of
