1. Discussion Physical Testing Laboratory In the physical laboratory, the focus of the group’s attention was on three different pieces of equipment: The HVI, the Universal Tensile Testing Machine, and the Denver Moisture Analyzer. The HVI, or High Volume Fiber Test System, grades mainly cotton fibers based on characteristics such as average length, length uniformity, color, strength, elongatio, fineness, and trash. The color and trash values are equivalent to the grades assigned using the USDA Cotton Grade Boxes. Grade is a 2 digit number based on trash content and color, specifically.
