This part of ISO 105 specifies a method for determining the resistance of the colour of textiles of all kinds and in all forms to ironing and to processing on hot cylinders.
Tests are given for hot pressing when the textile is dry, when it is wet and when it is damp. The end-use of the textile usually determines which test should be made.
A dry specimen (dry pressing) or a dry specimen covered with a wet cotton adjacent fabric (damp pressing) or a wet specimen covered with a wet cotton adjacent fabric (wet pressing) are pressed with a heating device at a specified temperature and pressure for a specified time.
