Fuego Repentino<\/strong><\/h2>\n\n\n\n

ISO 11612<\/strong><\/h3>\n\n\n\n

Establece los requisitos m\u00ednimos de desempe\u00f1o para la ropa protectora contra el calor y las llamas, indispensable para una amplia variedad de usos finales. Est\u00e1n destinados a proteger el cuerpo del trabajador, excepto sus manos, contra del calor y las llamas. La prueba debe realizarse en un maniqu\u00ed instrumentado seg\u00fan la ISO 13506, con un tiempo de exposici\u00f3n m\u00ednimo de 3 y m\u00e1ximo de 4 segundos, o hasta 8 segundos para multicapas, aunque no establece un l\u00edmite m\u00e1ximo para el porcentaje de quemaduras, como la NFPA 2112. Las especificaciones est\u00e1n de acuerdo con las regulaciones vigentes en el pa\u00eds de origen.<\/p>\n\n\n\n

ISO 13506<\/strong><\/h3>\n\n\n\n

Prueba la ropa de protecci\u00f3n completa contra el calor y las llamas utilizando un maniqu\u00ed instrumentado para evaluar el comportamiento y la resistencia al fuego repentino. Estas evaluaciones se registran gr\u00e1ficamente mediante sensores que, por su precisi\u00f3n, pueden medir todos los grados de quema. Una vez aplicada la llama durante el tiempo especificado en la norma ISO 11612, la lectura se realiza por un per\u00edodo de hasta 60 segundos, para una capa, o 120 segundos, para multicapas, despu\u00e9s de que cesa la llama, para evaluar la posibilidad de quemaduras en este intervalo.<\/p>\n\n\n\n

El informe concluyente debe registrar el tiempo de exposici\u00f3n a las llamas, las \u00e1reas de quema en porcentaje, el comportamiento de la muestra (si hubo emisi\u00f3n de humo, contracci\u00f3n, intensidad y duraci\u00f3n de la pos-combusti\u00f3n), volumen de humo generado durante y despu\u00e9s de la prueba, estabilidad dimensional, entre otros factores.<\/p>\n\n\n\n

ISO 15025<\/strong><\/h3>\n\n\n\n

Establece dos m\u00e9todos de prueba para limitar la propagaci\u00f3n de la llama. La post-llama en ambos m\u00e9todos debe ser inferior a 2 segundos. Se pueden evaluar tanto muestras textiles como muestras que contengan todo tipo de insumos que componen la prenda externamente (velcro, cremalleras, hilo, etc.).

Arco El\u00e9ctrico<\/strong><\/h2>\n\n\n\n

IEC 61482-2<\/strong><\/h3>\n\n\n\n

Establece los requisitos m\u00ednimos de certificaci\u00f3n, siendo similar a ASTM F 1506. Permite la evaluaci\u00f3n de la ropa por dos m\u00e9todos: IEC 61482-1-1 o IEC 61482-1-2.<\/p>\n\n\n\n

IEC 61482-1-1<\/strong><\/h3>\n\n\n\n

Eval\u00faa el desempe\u00f1o de materiales textiles o de confecci\u00f3n en presencia de un arco utilizando dos m\u00e9todos. El primero, el m\u00e9todo A, determina ATPV (similar a ASTM F 1959), HAF y ruptura en muestras de tejido; el segundo, m\u00e9todo B (similar a ASTM F 2621), eval\u00faa el desempe\u00f1o de las caracter\u00edsticas constructivas de la ropa en un maniqu\u00ed instrumentado.<\/p>\n\n\n\n

Como condici\u00f3n previa para la realizaci\u00f3n del ensayo, es necesario que los materiales textiles cumplan los requisitos de la norma ISO 15025 en cuanto a la extensi\u00f3n de la carbonizaci\u00f3n, que debe ser inferior a 100 mm, y la post-llama, que debe ser inferior a 2 segundos. Se diferencia de la NFPA 70E en que no lo separa en categor\u00edas de riesgo.<\/p>\n\n\n\n

IEC 61482 1-2<\/strong><\/h3>\n\n\n\n

Eval\u00faa el desempe\u00f1o de telas o ropa en presencia de un arco el\u00e9ctrico usando el m\u00e9todo de caja (Teste de Caixa). Clasifica los materiales probados en dos clases de protecci\u00f3n:
\u2022 Clase 1 - Corriente de prueba de 4 kA - 3,2 cal \/ cm\u00b2.
\u2022 Clase 2 - Corriente de prueba 7kA - 10.1 cal \/ cm\u00b2.
Utiliza informaci\u00f3n de ATPV de acuerdo con el m\u00e9todo A. IEC 61482-1-1.<\/p>","protected":false},"excerpt":{"rendered":"
