Conventional conditions for substitute tests

Test conditions with simulant D	Test conditions with isooctane	Test conditions with ethanol 95%	Test conditions with MPPO(1)
(1) MPPO = Modified polyphenylene oxide
(2) The volatile test media are used up to a maximum temperature of 60°C. A precondition of using these tests is that the material or article will withstand the test conditions that would otherwise be used with simulant D. Immerse a test specimen in olive oil under the appropriate conditions. If the physical properties are changed (eg melting, deformation) then the material is considered unsuitable for use at that temperature. If the physical properties are not changed then proceed with the substitute tests using new specimens.
