By using the EN 13773, this interlinks and unifies the results across Europe for testing purposes for 1 market.   Composition of Fabrics – Flame Retardant Standards Europe Understanding which fabrics pass which tests is important as you can have inherently flame retardant fabrics such as Trevira which are polyester fabrics with the flame retardant yarn so they do not need to be treated. This means they can be washed and they will keep their flame retardancy. Some fabrics that are treated will need to be retreated if they are not inherently flame retardant. Therefore a user needs to be mindful that after dry cleaning they may no longer be flame retardant.   Areas Used The European flame retardant standards will be required in any commercial environment, a hotel will require EN13773,  M1 B1 standards in Europe and BS5867 in the UK. They are all similar tests but it is required for insurance requirements to ensure that they are certified to avoid any legal risks.  

Understanding Different Fabric Flame Retardancy

Durably Flame Retardant Again these fabric have been chemically treated and will be suitable for washing. Inherently flame retardant An inherently flame retardant fabric is made from a yarn that has the flame retardancy already within the yarn like a Trevira. This means it can be washed multiple times and not loose its flame retardancy.
