Create a uniform test method complete with a procedure that contains a standard dirt formulation. Procedure for lab material to illustrate dirt repellent of a film and wash-ability with specifications. Overall to justify on a scale how dirt repellent is a film or how does the material in the material in the film help improve a dirt repellent.
The impetus behind developing a standard test method of this nature is to standardize the architectural coating market by combining joint collaborations and already existing in-house test methods. Coatings descriptions host details of dirt repellency. But how do these quantify against other manufacturers and/or suppliers who would like to improve dirt repellency.
The title and scope are in draft form and are under development within this ASTM Committee.
