scope:

This part of ISO 20947 specifies the protocol employed in evaluating the gap between the virtual garment and the virtual clone, the virtual twin or the virtual fit mannequin (fit form) model in the evaluation of the fitting performance of the virtual garment and the virtual human body. In this standard, gap means space between garment and human body which is indispensable for garment design and is an important factor for wearing comfort. For the purpose of evaluating this gap, the standard requires the reporting of whether the perimeter calculation function for the virtual garment and the virtual clone, the virtual twin or the virtual fit mannequin (fit form) model, the function for calculating the gap in measurements and area between the virtual garment and the virtual clone, the virtual twin or the virtual fit mannequin (fit form) model and the visualization function for gap, garment pressure, and grain are available or not. Also, evaluation of the perimeter of the virtual garment, the perimeter of the virtual clone, the virtual twin or the virtual fit mannequin (fit form) model and the gap in area between the virtual garment and the virtual clone, the virtual twin or the virtual fit mannequin in accordance with the method specified herein and reporting of the results are recommended. The users covered by this standard are those users planning to install or update digital fitting systems. Users (developers, designers, manufacturers, educationalists, retailers etc.) of digital fitting systems shall produce evaluation reports according to this standard and make such reports available to the users. This evaluation process is not limited to materials (e.g. woven). These figures are wearing woven fabric clothing. Soft fabrics, such as knitted materials, have different results.
