Scope
This part of GB/T 7690 specifies the method for determining the linear density of glass fiber, carbon fiber, aramid fiber, or other reinforcing fiber yarns.
This method is applicable to various types of yarns, including single yarns, twisted yarns, cables, deformed yarns, untwisted roving yarns, and fixed-length fiber yarns.
