leaching
release of substances from a material (e.g. coating), which pass through the external surface of the material

interfering elements that may affect the results of the test.
The equipment specified in 5.2.2 to 5.2.5 shall also be calibrated.
5.2 Equipment
5.2.1 Immersion container
The container for immersion shall be made of a material inert to the target substances of interest in the
eluates (e.g. glass, PTFE coated). The immersion container shall be large enough to allow the test specimens
to have the coated face completely exposed to water and contain 25 l water per squaremeter exposed face.
The water column above or below the test surface shall be ± 10 mm.
