AATCC 130-2000 Soil Release: Oily Stain Release Method. 6. Test Specimens 6.1 Use two test specimens 38 × 38 ± 1 cm (15.0 × 15.0 ± 0.4 in.) for each deter- mination. Condition the test specimens for a minimum of 4 h at 21 ± 1°C (70 ± 2°F) and 65 ± 2% RH prior to application of stains. 7. Staining Procedure 7.1 Place the unstained specimen flat on a single thickness of AATCC White Textile Blotting Paper on a smooth, horizontal surface. 7.2 Using the medicine dropper, place 5 drops (approx. 0.2 mL) of corn oil (see 12.3) in the approximate center of the test specimen. 7.3 Place a 7.6 × 7.6 cm (3.0 × 3.0 in.) square of glassine paper over the stained area. 7.4 Place the weight (see 5.5) on the glassine paper directly over the stained area. 7.5 Allow weight to sit undisturbed for 60 ± 5 s. Then remove the weight and discard the glassine sheet. 7.6 Do not allow stained test speci- mens to contact each other in a manner which would transfer stains. Wash within 20 ± 5 min after staining. 8. Washing Procedure 8.1 Fill washer to high water level with water at one of the temperatures from Table I. Check with the thermometer. 8.2 Add 100 ± 1 g of detergent to the washer. 8.3 Start the water agitating, place ballast and then test specimens in the washer making a total load of 1.80 ± 0.07 kg (4.00 ± 0.15 lb). The maximum number of test specimens per washer load shall be 30 with one stain per specimen. 8.4 Set the dial on the washer for a Normal wash to run for 12 min measured time and allow cycle to run to completion. (This gives normal agitation in both the wash and the rinse.) 8.5 At the end of the final spin cycle, place the entire load, test specimens and ballast, into the dryer. 8.6 Dry at Normal (Cotton Sturdy) set- ting at a time setting of 45 min or until dry. On some dryers a 5 min cooldown automatically follows the drying on the Normal (Cotton Sturdy) setting. For dry- ers without this feature dry at High set- ting for 45 ± 5 min and change setting to Air and run for 5 min. Maximum dryer stack temperature at the cabinet exit should be 65 ± 6°C (150 ± 10°F)...
