+: Material is highly resistant to the chemical; suitable for use.
O: Material resistance varies depending on conditions; limited suitability.

For materials classified as "limited suitability," the duration of exposure to the chemical must be considered. Prolonged exposure can lead to significant damage or destruction of the material. Consequently, these components are categorized as wear parts and excluded from standard warranty coverage.

Due to various factors, a definitive assessment may not always be possible.
