Conveyor belts - Fire simulation flammability testing - Part 1: Propane burner tests

EN 12881-1 describes four methods for measuring the propagation of a flame along a conveyor belt which has been exposed to a relatively high localized heat source such as a fire. The damage suffered by the conveyor belt, as well as its tendency to support combustion, is measured by observing the extent to which the fire spreads along the test piece.
Method A uses a test piece 2 m in length and consumes propane gas through the burner at the rate of (1,30 ± 0,05) kg per 10 min.
Method B uses a test piece 2,5 m in length and consumes propane gas through two burners mounted above and below the test piece trestle at the rate of (1,30 ± 0,05) kg per 10 min for each burner.
Method C uses a test piece 1,5 m in length and consumes propane gas through the burner at the rate of (565 ± 10) g per 50 min.
Method D uses a test piece 1,2 m in length and consumes propane gas through the burner at the rate of
150 l/hr (D1) or 190 l/hr (D2).

Fördergurte - Brandtechnische Prüfungen - Teil 1: Prüfungen mit dem Propanbrenner

Dieser Teil der EN 12881 legt drei Verfahren zur Bestimmung der Ausbreitung einer Flamme entlang eines Fördergurtes fest, der einer örtlichen Wärmequelle, wie Feuer, ausgesetzt war. Es wird sowohl die Beschädigung des Fördergurtes gemessen als auch seine Neigung, die Verbrennung zu unterstützen, wobei das Fortschreiten der Flamme entlang des Probekörpers beobachtet wird.
Für Verfahren A wird ein 2 m langer Probekörper verwendet, wobei der Propangasverbrauch des Brenners (1,30 ± 0,05) kg in 10 min beträgt.
Für Verfahren B wird ein 1,5 m langer Probekörper verwendet, wobei der Propangasverbrauch des Brenners (565 ± 10) g in 50 min für jeden Brenner beträgt.
Für Verfahren C wird ein 1,2 m langer Probekörper verwendet, wobei der Propangasverbrauch des Brenners 150 l je h (D1) oder 190 l je h (D2) beträgt.

Courroies transporteuses - Essais de simulation d'inflammation - Partie 1: Essais avec brûleur propane

L’EN 12881 1 décrit quatre méthodes de mesurage de la propagation d’une flamme sur une courroie transporteuse qui a été exposée à une source de chaleur localisée relativement élevée, comme par exemple un feu. La détérioration de la courroie transporteuse est mesurée, ainsi que sa tendance à entretenir la combustion, en observant le degré de propagation du feu sur l’éprouvette.
La méthode A utilise une éprouvette de 2 m de long et consomme du gaz propane à l’aide du brûleur, avec un débit de (1,30  0,05) kg par 10 min.
La méthode B utilise une éprouvette de 2,5 m de long et consomme du gaz propane à l’aide de deux brûleurs montés au-dessus et en-dessous du tréteau de l’éprouvette, avec un débit de (1,30  0,05) Kg par 10 min pour chaque brûleur.
La méthode C utilise une éprouvette de 1,5 m de long et consomme du gaz propane à l’aide du brûleur, avec un débit de (565  10) g par 50 min.
La méthode D utilise une éprouvette de 1,2 m de long et consomme du gaz propane à l’aide du brûleur, avec un débit de 150 l/h (D1) ou 190 l/h (D2).

Naprave za kontinuirni transport - Trakovi tračnih transporterjev - Požarnovarnostni preskusi - 1. del: Preskusi s propanskim gorilnikom

Standard EN 12881-1 opisuje štiri metode za merjenje širjenja ognja po traku tračnega transporterja, ki je bil izpostavljen razmeroma visoki koncentraciji lokaliziranega toplotnega vira, kot je ogenj. Tako škoda, ki jo utrpi trak tračnega transporterja, kot tudi težnja k zgorevanju se meri z opazovanjem tega, v kakšnem obsegu se ogenj razširi po preskušancu. Metoda A uporablja preskušanec z dolžino 2 m in propan skozi gorilnik porablja s hitrostjo (1,30 ± 0,05) kg na 10 minut. Metoda B uporablja preskušanec z dolžino 2,5 m in propan skozi dva gorilnika, nameščena nad in pod oporo preskušanca, porablja s hitrostjo (1,30 ± 0,05) kg na 10 minut za posamezni gorilnik. Metoda C uporablja preskušanec z dolžino 1,5 m in propan skozi gorilnik porablja s hitrostjo (565 ± 10) g na 50 minut. Metoda D uporablja preskušanec z dolžino 1,2 m in propan skozi gorilnik porablja s hitrostjo 150 l/uro (D1) ali 190 l/uro (D2).
