The specifications laid down in this International Standard apply to the testing of surfaces which may become contami-nated by radioactive materials.
Decontaminability data obtained using this test method are not applicable to technical systems where layers of contaminating materials are formed as a result of long-term application of higher temperatures and pressures (for example primary cir-cuits of nuclear reactors).
The purpose of the test is to assess the ease of decontamina-tion of surfaces under laboratory conditions. In practical ap-plications, it may be important to consider other qualities, such as chemical, mechanical and radiation resistance and long-term stability in the selection of the materials to be used. It should be recognized that further decontamination tests under simulated service conditions may be needed.
