Water Absorption (ISO 62)

Under standard climate conditions and water immersion:

  • Water absorption causes a change in length, typically between one‑quarter and one‑third of the absorbed water content. This means: 1% water absorption results in a 0.25–0.33% increase in length.

Under standard climate conditions:

  • Percentage increase in the plastic’s weight due to water absorption
  • Storage under standard climate conditions: temperature 2 °C, relative humidity 50%

Under water immersion:

  • Percentage increase in the plastic’s weight due to water absorption
  • Storage in water
