Full Description

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.
