ASTM D1025-2010 Standard Test Method for Non-Volatile Residues in Coalescence Grade Butadiene specifies a standard test method for determining the content of non-volatile residues in coalescence grade butadiene. This method involves heating the sample to a specified temperature so that the volatile matter in it is completely evaporated, and then weighing the residual non-volatile matter. This test helps to evaluate the purity and mass of butadiene to ensure that it is not affected by undesirable impurities during the coalescence process. This standard is suitable for manufacturers of coalescence grade butadiene and quality control laboratories to ensure that it meets product performance requirements and effectively controls the content of impure substances in production.
