Resistance to Chemicals Test

According to ISO 175:210 standard

In many real application cable protection systems are exposed to chemicals.
Extensive data is available for the compatibility of various plastic materials with many different chemicals. This data can be used for assessment of compatibility for specific applications. PMA publishes a compatibility list for the most commonly occurring combinations of plastic and chemical.
If chemicals are mixed or if no data is available for an assessment PMA recommends a compatibility test.
Changes to appearance, dimensions and mechanical characteristics are assessed after long term exposure to the chemical to confirm compatibility.
