AATCC 107:2007 pdf download.Colorfastness to Water
2.1 The specimen, backed by multifi- ber test fabric, is immersed in water un- der specified conditions of temperature and time, and then placed between glass or plastic plates under specified condi- tions of pressure, temperature and time. The change in color of the specimen and the staining of the attached multifiber test fabric are observed.
3. Terminology
3.1 colorfastness, n.—the resistance of a material to change in any of its color characteristics, to transfer of its color- ant(s) to adjacent materials or both, as a result of the exposure of the material to any environment that might be encoun- tered during the processing, testing, stor- age or use of the material.
4. Safety Precautions
NOTE: These safety precautions are for information purposes only. The pre- cautions are ancillary to the testing proce- dures and are not intended to be all inclu- sive. It is the user’s responsibility to use safe and proper techniques in handling materials in this test method. Manufac- turers MUST be consulted for specific details such as material safety data sheets and other manufacturer’s recommenda- tions. 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.
11.1 Precision. Precision for this test method has not been established. Until a precision statement is generated for this test method, use standard statistical tech- niques in making any comparisons of test results for either within-laboratory or between-laboratory averages.
11.2 Bias. Colorfastness to water can be defined only in terms of a test method. There is no independent method for de- termining the true value. As a means of estimating this property, the method has no known bias.
12.2 AATCC Perspiration Tester: Put all 21 glass or plastic plates into the unit regardless of the number of specimens. After the final glass or plastic plate is put in position on top, set the dual plates with compensating springs in posi- tion. Place the 3.6 kg (8.0 lb) weight on top making a total of 4.5 kg (10.0 lb) under the pressure plate. Lock the pressure plate in position by turning the thumb-screws. Remove the weight. Place the unit in the oven on its side, so that the plates and the specimens are vertical.AATCC 107 pdf download.
