For other temperatures use:
PT = P20°C / (0.026 T°C + 0.48), where P ≡ bar/m
PT = P68°F / (0.014 T°F + 0.05), where P ≡ psi/ft
Warning: Oxidizing agents such as nitric acid attack organic ion exchange resins under certain conditions. This could lead to
anything from slight resin degradation to a violent exothermic reaction (explosion). Before using strong oxidizing agents, consult
sources knowledgeable in handling such materials.
