Get more information about the standard at ASTM D4281-95(2005)e1.
The ASTM D4281 standard was withdrawn due to its reliance on Freon (chlorofluorocarbons, CFCs), which are known to deplete the ozone layer and contribute to environmental damage. As international regulations, such as the Montreal Protocol, phased out the use of CFCs, the standard became obsolete and was no longer sustainable for modern industry practices.
