Protective clothing and accessories complying with this international standard is intended to protect the user against occasional and brief contact with small igniting flames, in circumstances where there is no significant heat hazard and without the presence of another type of heat. Where protection against heat hazards is necessary, ISO 11612 is recommended.  
Protective clothing according to EN ISO 14116 may consist of several separate garments, or a single garment with one or more layers. All assemblies claiming compliance with this standard shall achieve a limited flame spread index of 1, 2 or 3. 
Limited flame spread index; 

Index 1 (flame spread, flaming debris and afterglow properties) 

Index 2 (as index 1 and included hole formation properties) 

Index 3 (as index 2 and included after flame properties) 
If the index is 1 (lowest level) the garment can only be used outside a garment that fulfills index 2 or 3. Index 1 may not have skin contact, e.g. neck or wrist.  
 
EN ISO 14116 is not symbolized by any pictogram, however Blåkläder marks flame resistant products with a flame symbol in marketing material.
