New Test Method for Measuring the Evaporative Resistance of Clothing Items Using Heated Manikin Body Forms
1. Scope
The proposed scope is a standardized test method for the isothermal measurement of the evaporative resistance of clothing items and/or ensembles using hand, foot, and head form heated manikins when subjected to a standardized environmental challenge. The measurement is obtained by means of a heat loss method. The method may be expanded in future revisions to include measurements made using additional body part forms.

Rationale
This method will supplement the thermal insulation characterization accomplished via ASTM F3426 to provide a more wholistic characterization of the performance of clothing worn on the extremities. The standard will be used for the measurement of evaporative resistance of clothing intended to cover the hands, feet, or head of an end user. The method characterizes the impact of three-dimensional garment form, fit, and features on these evaporative resistance measurements with higher resolution than that which can be achieved using ASTM F2370. This will enable increased accuracy and confidence in assessing the performance of these types of clothing, allowing for objective comparisons to be drawn between clothing items. This method will also enable the high-resolution measurement of important parameters influencing human physiological responses, enabling advancements to the field of clothing science. Primary users of this standard will include but are not limited to clothing manufacturers, academic or research institutions, materials manufacturers, and regulatory agencies.
The title and scope are in draft form and are under development within this ASTM Committee.
