Improved soil standards from AATCC
The committee also worked to clarify the materials included in the formula. Iron oxide is now specified as black iron oxide. Silica and peat moss are also described more precisely to ensure consistent performance and consistent test results.
The synthetic soil was developed for standardized carpet soiling. It is also referenced in a draft test method for stain resistance of launderable fabrics. The formulation originally appeared in AATCC TM123 Carpet Soiling: Accelerated Soiling Method. This method was withdrawn in 2010 and the soil preparation was transferred to an Appendix of AATCC TM122 Test Method for Carpet Soiling: Service Soiling. As the committee considers future changes to AATCC TM122 as well as related ASTM standards, it made sense to create a separate standard that all could reference for synthetic soil preparation.
