At\u00e9 mesmo pequenas part\u00edculas - vis\u00edveis apenas sob um microsc\u00f3pio - causam desgaste, gripagem e falha prematura em componentes de precis\u00e3o, como servov\u00e1lvulas, bombas de pist\u00e3o e v\u00e1lvulas de controle direcional. O <a href=\"https:\/\/www.iso.org\/standard\/72618.html\">ISO 4406<\/a> fornece uma linguagem universal para a comunica\u00e7\u00e3o dos n\u00edveis de limpeza de fluidos, permitindo que os engenheiros especifiquem os requisitos, monitorem as condi\u00e7\u00f5es e selecionem a filtragem adequada.<\/section>\n<section class=\"definition\">\n<h2>O que \u00e9 a ISO 4406?<\/h2>\n<p>A ISO 4406:1999 \u00e9 o padr\u00e3o internacional para codificar o n\u00edvel de contamina\u00e7\u00e3o por part\u00edculas s\u00f3lidas em fluidos hidr\u00e1ulicos. A norma usa um c\u00f3digo de tr\u00eas n\u00fameros separados por barras, como 19\/17\/14, em que cada n\u00famero representa uma faixa de tamanho de part\u00edcula.<\/p>\n<p>Os tr\u00eas n\u00fameros correspondem a:<\/p>\n<ul>\n<li><strong>Primeiro n\u00famero<\/strong>: Part\u00edculas \u2265 4 \u03bcm (por mL)<\/li>\n<li><strong>Segundo n\u00famero<\/strong>: Part\u00edculas \u2265 6 \u03bcm (por mL)<\/li>\n<li><strong>Terceiro n\u00famero<\/strong>: Part\u00edculas \u2265 14 \u03bcm (por mL)<\/li>\n<\/ul>\n<p>A ISO 4406 mede part\u00edculas usando contadores de part\u00edculas a laser.
