The method is not applicable to materials to be laid edge to edge as tiles. 5 PROCEDURE 2 PRINCIPLE 5.1 Pre-treatment The total dimensions in the warp direction (or direction of Spread the textile floor covering on a smooth, flat manufacture) and in the weft direction (or direction at horizontal surface so that no crinkles are present and allow right angles to the direction of manufacture), excluding it to relax for not less than 48 h. fringes, of the relaxed textile floor covering are measured in at least three places and the average dimensions for each direction calculated. In addition, for pile carpets, the 5.2 Measurements distance between the outer edge of the base of the pile and the nearest outermost edge of the carpet is determined, and 5.2.1 Make each measurement of length and width (A, the length of fringe, if present, is determined. and Aw) between the outermost edges of the textile floor covering including any backing or binding that may be present, but excluding fringes (see the figure). This is the 3 DEFINITIONS "total length" and "total width". For the purposes of this International.

The "length of the warp direction (or direction of manufacture) between pile section" and "width of pile segtion" can then be the
