Terminology 3.1 carpet, n.—all textile floor cover- ings not designated as rugs. 3.2 soil, n.—dirt, oil or other sub- stances not normally intended to be present on a substrate such as a textile material. 3.3 soiling, n.—in textiles, a process by which a textile substrate becomes more or less uniformly covered with/or impregnated with soil. 3.4 textile floor covering, n.—an article having a use-surface composed of textile material and generally used for covering floors. 3.5 use-surface, n.—of textile floor covering, the part of a textile floor covering directly exposed to foot traffic. 3.6 accelerated soiling, service soiling, and other key terms will be added when definitions are agreed upon. 4. Safety Precautions NOTE: These safety precautions are for information purposes only. The precautions are ancillary to the testing procedures and are not intended to be all inclusive. It is the user’s responsibility to use safe and proper techniques in handling materials in this test method. Manufacturers MUST be consulted for specific details such as material safety data sheets and other manufacturer’s recommendations. All OSHA standards and rules must also be consulted and followed. 4.1 Good laboratory practices should be followed. Wear safety glasses in all laboratory areas. 4.2 Manufacturer’s safety recommen- dations should be followed when operat- ing laboratory testing equipment. 5. Apparatus and Materials 5.1 Jar mill, laboratory, ball, roller type, direct motor driven, 1 L (1 qt) (see 13.1). 5.2 Jar, ball, mill, porcelain, approx. 1 L (1 qt) (see 13.2). 5.3 Flint pebbles, 1.9-2.5 cm (0.8-1.0 in.) diam (see 13.3). 5.4 Soils. 5.4.1 Soil (vacuum cleaner sweepings) (see Section 7). 5.4.2 Synthetic soil (see Section 8). 5.5 Vacuum cleaner: tank type; 120 volts; 750 watts; 50-60 cycles; use fabric or upholstery attachment. 6. Test Specimens 6.1 Cut two specimens, each 18 cm (7 in.) in warp direction of tufting and 9 cm (3 in.) in filling direction or across tufting direction. 6.2 Condition specimens at room tem- perature for 16 h prior to use. 7. Soil Preparation 7.1 Take sweepings from a vacuum cleaner. For maximum reproducibility use sweepings from several vacuum cleaners within the surrounding area of the testing facilities. 7.2 Pass sweepings through a 20-mesh screen and then through a 100-mesh screen. 7.3 Take soil which finally passes through the 100-mesh screen and sterilize it (for health reasons) by steaming for 30 min; then air...
