Determinaci\u00f3n del punto inferior de explosi\u00f3n (PIE)<\/h1>\n

El punto inferior de explosi\u00f3n es la temperatura de un l\u00edquido inflamable a la que la concentraci\u00f3n del vapor saturado en el aire es id\u00e9ntico al l\u00edmite inferior de explosi\u00f3n.<\/p>\n

La determinaci\u00f3n del punto inferior de explosi\u00f3n se realiza an\u00e1logamente a la norma DIN\u00a0EN\u00a015794. El aparato de prueba utilizado se muestra en la figura\u00a01<\/strong>. Para la comprobaci\u00f3n se llenan aproximadamente 120\u00a0\u2013\u00a0140\u00a0gramos del producto en un cilindro de vidrio (\u00d8 = 88\u00a0mm; H\u00a0=\u00a0320\u00a0mm). La temperatura en el cilindro de vidrio es regulada a trav\u00e9s de una camisa doble mediante un term\u00f3stato del tipo Ministat\u00a0230 de la empresa Huber.<\/p>\n

\"\"<\/p>\n

Se registran las temperaturas de la muestra y de la fase gaseosa encima. La muestra es almacenada durante por lo menos 0,5 horas para que haya suficiente tiempo para el ajuste del equilibrio. Despu\u00e9s del per\u00edodo de atemperado se comprueba mediante una chispa (energ\u00eda >\u00a01\u00a0J) si la atm\u00f3sfera de gas encima de la muestra puede ser encendida.<\/p>\n

Durante la medici\u00f3n se registra la presi\u00f3n atmosf\u00e9rica.<\/p>\n

La temperatura m\u00e1xima a la que ya no hay ninguna ignici\u00f3n se toma como \u00abpunto inferior de explosi\u00f3n con la presi\u00f3n atmosf\u00e9rica actual\u00bb PIE0<\/sub> debiendo ser convertida con la presi\u00f3n atmosf\u00e9rica en el momento de la medici\u00f3n con arreglo a la siguiente f\u00f3rmula de correcci\u00f3n para obtener la presi\u00f3n est\u00e1ndar (1013\u00a0hPa):<\/p>\n

PIE = PIE0<\/sub> + 0,025 \u2022 (1013 \u2013 p);
\ncon PIE = punto inferior corregido de explosi\u00f3n en \u00b0C; PIE0 <\/sub>= punto inferior medido de explosi\u00f3n en \u00b0C y p = presi\u00f3n atmosf\u00e9rica en hPa<\/p>\n
