Effect of flame retardant on char formation of wood at medium rise temperatures / Sahab Singh in PAINTINDIA, Vol. LVII, N° 2 (02/2007)

[article]  inPAINTINDIA > Vol. LVII, N° 2 (02/2007) . - p. 105-108 Titre : Effect of flame retardant on char formation of wood at medium rise temperatures Type de document : texte imprimé Auteurs : Sahab Singh, Auteur Année de publication : 2007 Article en page(s) : p. 105-108 Note générale : Bibliogr. Langues : Anglais (eng) Index. décimale : 667.9 Revêtements et enduits Résumé : The effect of flame retardant phosphatized amino resin based flame retardant on wood specimens treated with various concentrations was examined by weight loss method. As the retention of resin became higher, the char formed rapidly on wood surface, providing thermal barrier over the surface of wood and also stopping the gas flow. Specimens were impregnated with vacuum impregnation method. The treated specimens were subjected to 350°C.

Perfomance of fire resistant sealant under live power and intense flame / Harpal Singh in PAINTINDIA, Vol. L, N° 6 (06/2000)

[article]  inPAINTINDIA > Vol. L, N° 6 (06/2000) . - p. 41-46 Titre : Perfomance of fire resistant sealant under live power and intense flame Type de document : texte imprimé Auteurs : Harpal Singh, Auteur ; J. P. Jain, Auteur ; Sahab Singh, Auteur Année de publication : 2000 Article en page(s) : p. 41-46 Note générale : Bibliogr.

For PVC cable fire stop barrier specimens have been prepared using fire resistant sealant as heat penetration sealing material and their fire performance under live power supply evaluated by employing standard test methods. Fire resistant sealant is quite effective in preventing the heat penetration from exposed surface to another side of the specimens. Electric circuit failure times of the specimens are also enhanced by the use of fire resistant sealant.

Sealant fire stops for cable installations / Sahab Singh in PAINTINDIA, Vol. LVI, N° 11 (11/2006)

[article]  inPAINTINDIA > Vol. LVI, N° 11 (11/2006) . - p. 69-73 Titre : Sealant fire stops for cable installations Type de document : texte imprimé Auteurs : Sahab Singh, Auteur ; N. S. Tyagi, Auteur Année de publication : 2006 Article en page(s) : p. 69-73 Note générale : Bibliogr. Langues : Anglais (eng) Index. décimale : 667.9 Revêtements et enduits Résumé : A method has been developed to conduct fire performance evaluation test of through penetration cable fire stop. The method is based on time temperature history, exposed to a high heat source typical of building Ires. The cable fire stop was prepared with a chemical formulation developed for intumescent sealing mastic. The test provides information relating to the thermal stability of intumescent char formed on the reaction of chemicals which quickly fills the hollow spaces formed by burning insulation cables. Trapped noncombustible gases within the intumescent cellular char provides insulating abilities which protects the more deeply located cables or conductors from further radiation. Metal hydroxide releases water, which causes intensive cooling of the hot surfaces, interrupting the heat transfer process taking place through the conductor.
