The original German document, upon which this English translation is based, utilises the term 'Dämmschichtbildner', which roughly (or directly) translates to "creator of a layer of insulation". This term, however, is not entirely descriptive of all intumescents, by definition, which may indeed swell and thus increase their volume and decrease their density. The term 'Dämmschichtbildner' is most applicable to thin film intumescents, which create a soft foam, which envelops a substrate as in spray applied fireproofing, or the interior of certain firestop pillows. However, the term is hardly descriptive of certain high strength, high pressure and lower volume intumescents, such as are used at times in plastic pipe firestop devices utilising sodium silicates and graphite. The latter intumescents, on their own, don't always create a uniform layer of insulation, which would not be defeated by convection. This is because they do not undergo a uniform bubbling process, or a 'liquid stage' and thus are also less endothermic. However, since ALL intumescents, high strength and low strength must be tested the same way (if they are to be marketed in Germany that is), the translation will use the term 'intumescent', as opposed to "creator of a layer of insulation", or the previous edition's version "materials that foam up under the influence of fire". http://www.geocities.com/ghering2000/dibt2.html
Intumescents are defined as follows in the Glossary:
Intumescent: Substances which swell as a result of heat exposure thus increasing in volume and decreasing in density. Intumescents are typically endothermic to varying degrees, as they can contain chemically bound water. Intumescents are used in firestopping, fireproofing and gasketing applications. Some intumescents are susceptible to environmental influences such as humidity, which can reduce or negate their ability to function. DIBt approvals quantify the ability of intumescents to stand the test of time against various environmental exposures. DIBt approved firestops and fireproofing materials are available in Canada and the US. 3M Canada is one such vendor.

Non è un semplice rivestimento protettivo , ma un rivestimento "intumescente" a auto-espandente (vedi sopra: Intumescent: Substances which swell as a result of heat exposure thus increasing in volume and decreasing in density.)
