SN/T 4570-2016 is the English-translated version of 石油及石油产品中氯和溴含量的测定波长色散X荧光光谱法.

SN/T 4570-2016 — This standard specifies additives for liquid petroleum products, synthetic oils and fluids, petroleum products (including used oils) Wavelength Dispersive X-Ray Fluorescence Spectrometry of Chlorine and Bromine in Organic Solvents Containing Known Chlorine and Bromine Contents.

This standard applies to liquid petroleum products, synthetic oils and fluids, petroleum products (including used oils) additives (both soluble and free Determination of chlorine and bromine in organic solvents containing known chlorine and bromine content.

The scope of determination of this method. the mass fraction of chlorine is 0.0005%~ 0.1000%, bromine mass fraction 0.0010% ~ 0.1000%. Although the mass fraction of lead greater than 0.1500% can cause interference, it His elements generally do not interfere (see note 2).

Note 1. The unit % in this method is used to indicate the mass fraction of a substance. Note 2. Since the lubricant may contain high concentrations of a wide range of interference elements, it is easy to produce special problems.

But for used lubricants, even if it is with the situation described in the last paragraph of 9.3, the lowest sensitivity can reach 0.0050%.
