Textiles - Determination of the resistance of cellulose-containing textiles to micro-organisms - Soil burial test - Part 2: Identification of long-term resistance of a rot retardant finish (ISO 11721:2003)
ISO 11721-2:2003 describes a test procedure for identification of the long-term resistance of a rot-retardant finish against the attack of microorganisms in the soil.It permits a distinction to be made between rot-retardant finishes with no long-term resistance, with regular long-term resistance and with increased long-term resistance, in order to assess the suitability for use in the tropics.As the soil burial test is a biological process and the test soil not accurately defined, ISO 11721-2:2003 only covers the comparison of finished and unfinished specimens.
