II. Requisitos para outros dispositivos, exceto dispositivos port\u00e1teis ou individuais <\/p>\n\n\n\n

Se a capacit\u00e2ncia medida de qualquer parte condutora exceder os valores indicados no quadro 11, o equipamento deve ser marcado com o s\u00edmbolo \u201cX\u201d adequado e as condi\u00e7\u00f5es especiais de utiliza\u00e7\u00e3o devem especificar o valor da capacit\u00e2ncia medida, para que o utilizador possa determinar a aplicabilidade em aplica\u00e7\u00f5es espec\u00edficas.
