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.
3.2 migration, n.—the nonuniform movement and distribution of dyes, pig- ments, finishes or other materials from one part of a material to another.
3.3 spotting, n.—in cleaning, applica- tion of solvent or solution to a material prior to or after commercial scouring, laundering, or drycleaning to remove or enhance removal of soil or stains in a lo- cal area.
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.
4.3 Perchloroethylene is toxic by inha- lation, by repeated contact with skin and by ingestion; it should be used only in a well vented atmosphere. Toxicology studies with laboratory animals have shown evidence of cancer in rats and mice exposed to perchloroethylene va- pors at 100-400 ppm concentrations for prolonged times. Fabric saturated with this solvent should be dried in an ade- quately ventilated hood. Use chemical goggles or face shield, impervious gloves and an impervious apron when handling perchloroethylene.
4.4 An eyewash/safety shower should be located nearby and an organic vapor respirator should be readily available for emergency use.AATCC 157 pdf download.
