    Microporous functional membrane—Measurement for Porosity—Absorption method by cetane

    GB/T 33052-2016 "Microporous functional films - Test method for porosity - Hexadecane absorption method" specifies the test method for determining the porosity of microporous functional films using the hexadecane absorption method. It is applicable to polyolefin microporous membranes and various coated separators. By allowing the film to absorb hexadecane, the porosity is calculated based on the relationship between the absorption amount and the pore volume. The test requires control of environmental conditions such as temperature. The detection requires an electronic balance with an accuracy of 0.1 mg, a constant-temperature water bath, a desiccator, and a thickness gauge with a measurement pressure of 17 kPa to 23 kPa and an accuracy of 1 μm, providing a standardized approach for measuring the porosity of films.
