      Format Pages Price  
    Photographs   $121

    This combination product includes both the adjunct (ADJD225503) and a copy of D 2255.

    Series 3-79 - This adjunct includes photographs for Yarn Number Range 24s/1 to 36s/1 (25 to 16 Tex)

    A series of photographic prints representing four appearance grades - A, B, C, and D in six ranges of yarn numbers. Grade A is the highest and the others are progressively lower.

    The appearance grades are based on composite evaluations of several factors, including yarn evenness, fuzziness, and neppiness. For ease in comparison grading, the same yarn is used for all grades in a series. A near mid-range size was selected to represent equal steps between adjacent grades using yarns produced with current commercial manufacturing equipment and practices. The use of offset printing provides better yarn definition and uniformity from set to set.

    Each photograph is 6 inches x 10 inches in size and the four photographs representing Grades A to D of each series are mounted on a 27.5 inches x 15 inches extra heavy board.

    A copy of the current ASTM standard is included with the purchase of this adjunct.
