Tech/Engineering - Metallurgy / Casting | | English term or phrase: char | | XXX and XXX fireproofing materials are designed to react to the heat generated during a fire and to intumesce - or to “swell up” - providing a tough and stable insulating layer(also known as char) over the steel. XXX reacts in a fire to form an insulating char |

"char" betyder egentligen tjära, men vi brukar kalla det isolerande skikt som bildas när brandskyddsfärgen sväller upp för "skum" |

Intumescent fire resistive coatings typically expand approximately 15 to 30 times during a UL 263; Fire Tests of Building Construction and Materials (ASTM E119, NFPA 251, and UBC 7-1) fire test. The more traditional insulating materials typically undergo a slight shrinkage during the fire exposure. In addition, most intumescent coatings generate an ash-like or char layer during their expansion process. As the fire exposure continues, the ash coating erodes exposing the remaining intumescent coating. This expansion process repeats itself several times during the test depending upon the coating thickness. The maintenance of the insulating or char layer during the expansion and the erosion process is much more dependent upon the shape of the structural steel as compared to maintaining the insulating barrier when more conventional materials are used. For example, while the char may adhere well to a wide flange column, the same material may not adequately adhere to and protect rectangular or round steel shapes. Some intumescent coatings require the addition of a reinforcing mesh when applied on specific structural shapes to retain their insulating or char layer.
