En ciertos papeles, particularmente los destinados a envolver metales, es de gran interés que no contengan substan-cias que puedan atacar a éstos. La presencia de cloro, cloruros o ácidos en el papel, hace a éste inadecuado para envolver objetos de hierro, acero o aluminio, en los que originaría la formación de óxidos. Igualmente un papel con azufre, sulfuros o sulfitos, que se aplicara a envolver objetos de plata, cobre o aleaciones cupríferas, originaría en éstos una corrosión por la formación de compuestos sulfurados. Esta norma tiene por objeto indicar unos métodos, para la investigación de dichas substancias en el papel de em-balajes.
