164. Testing for length and width of piece-goods.- (1) In testing for length of piece-goods such as are ordinarily sold by the length or by the piece the measurement shall be made along the selvage. (2) In testing piece-goods aforesaid for width the cloth shall be measured by each of the following methods and the mean of the measurements so taken shall be adopted. Care shall be exercised in applying each method to select a portion of the cloth where the creases are fewest, and the warp and weft respectively as straight as possible: (a) A double-fold of the cloth shall be laid on the table and the creases smoothed out, so that it may lie perfectly flat. The measuring rod shall then be placed across the cloth, and the finger and thumb run down the rod on each side of it across the cloth so as to once more flatten the creases. Care shall be taken in doing this to see that whilst the creases are smoothed out, stretching is avoided and the warp threads remain perpendicular to the rod. The measurement shall then be recorded. (b) A fold of the cloth shall be taken, and the doubled edge held between a finger and thumb at each end, and extended over the measuring rod which shall be kept flat on the table. The extension shall be sufficient to remove the creases but not to stretch the warp out of the perpendicular. |
