SY/T 0545-2012 (English Version) PDF

Scope: Warning: Personnel using this standard should have experience in regular laboratory work. This standard does not point out all possible safety issues. Users are responsible for taking appropriate safety and health measures and ensuring compliance with the conditions stipulated in relevant national laws and regulations. This standard specifies the method for using differential scanning calorimetry (DSC) to determine the wax precipitation heat characteristic parameters of crude oil such as wax precipitation point, wax precipitation peak temperature, wax precipitation peak temperature range, and wax precipitation heat enthalpy. This standard is applicable to the determination of waxing heat characteristic parameters of crude oil with a water content of no more than 0.5%.
