適用范圍：1.1 This standard ( Part IV ) prescribes a method for determination of the pile height, that is, tuft leg length above woven ground.1.1.1 The tuft leg length above woven ground is the same as pile height when the pile is in the vertical position. Generally, the hand-knotted carpets have unidirectional pile, that is, the tufts lie at an angle to the ground opposite to the direction in which weaving has been proceeded. If the tufts are not measured in vertical position, the observations may not give correct results about the pile height rather it would give the measurement of pile thickness.
