HG/T 6486-2026Determination of VOCs dynamic adsorption capacity for molecular sieves (English PDF)

HG/T 6486-2026 is the English-translated version of 分子筛对挥发性有机物（VOCs）动态吸附容量测定方法.

HG/T 6486-2026 gives a method for determining the dynamic adsorption capacity of molecular sieves for volatile organic compounds (VOCs). It applies to raw molecular sieve powder and to strip-shaped and spherical molecular sieves of all kinds used for removing VOCs. Dynamic adsorption means that the gas stream passes through the sieve while the uptake is measured, which reflects use in an abatement system better than a static test, and the document sets out how this measurement is made so that results from different laboratories can be compared.

Molecular sieve producers, makers of VOC treatment equipment, users who buy sieves for exhaust gas treatment and test laboratories can apply it. It is voluntary, as the /T in the code indicates. The Ministry of Industry and Information Technology issued it on 16 April 2026, and it takes effect on 1 November 2026. It is a new standard.
