EN 13773 Textile Products - Combustion Behavior

EUROLAB, with its state-of-the-art accredited laboratories and expert team, provides precise and fast testing services within the scope of EN 13773 testing. This standard specifies a classification scheme for the burning behavior of vertically oriented fabrics intended for curtains and drapes and similar uses.

Many ways have been tried to break the burning cycle of textiles. One of these ways is to use materials that can thermally decompose as a result of strong endothermic reactions inside the fiber. If sufficient heat can be absorbed as a result of these reactions, the pyrolysis temperature of the fiber will not be reached and combustion will not occur.

The third way to achieve flame retardancy is to change the pyrolysis mechanism to produce less burning volatile matter and more ash. This dense structure mechanism is seen in flame retardants containing phosphorus. As a result of cross-linking of phosphoric acid formed during thermal decomposition with polymers containing hydroxyl groups, less flammable products are released.

The most important flame retardants can be classified into three categories. These are basic flame-retardant materials based on phosphorus and halogens, have a low-flammability effect when used alone, synergistic substances that increase their effectiveness when used with basic flame-retardants (such as the use of phosphorus with nitrogen, halogens and antimony), and flame-retardant substances that reveal their activity through physical effects.
