This international standard specifies a method for the measurement of flame spread properties of vertically oriented textile fabrics intended for apparel, curtains, draperies and large tents including awnings and marquees, in the form of single or multicomponent (coated, quilted, multilayered, sandwich construction and similar combinations) fabrics.
