GB/T 38265.3-2022 《Test methods for soft soldering fluxes—Part 3:Determination of acid value—Potentiometric and visual titration methods》 Related products

GB/T 38265.3-2022 is the third part of the soft flux testing standard. It provides the potential Titrimetric method and the visual Titrimetric method for determining the acid value of the soft flux. The acid value affects the activity of the soft flux and the welding effect, which is an important mass index. The standard specifies the operation steps and key details of the two Titrimetric methods in detail, so that the detection is more standardized and the results are more comparable. It is suitable for soft flux production, mass supervision and other links, providing a strong basis for ensuring the mass of the soft flux and improving the welding process level.
