  • Basic weight ( g / ㎡ ) : In accordance with DIN EN ISO 536, a test is performed with filter papers from 500㎠ to 1,000㎠
  • Thickness ( mm ) : In accordance with DIN EN ISO 534, the value measured with a thickness measurer under pressure
    of 10N / ㎠
  • Filtration speed (s / 10ml ) : Fold a filter paper with a diameter of 110m in quarter and soak it.
    Then, hang it and filter 10 ml of distilled water at 20 °C. Time that it takes for filtration is measured.
  • Retention rate ( ㎛ ) : Retention rate is calculated by test methods of filter paper manufactures. As each manufacturer has a
    different test method, use these data for reference only.
  • Ash Contents ( % ) : Weight of residues after 10g of filter paper is ignited in platinum crucible at 800℃.
