GB/T 11203-2001 《Rubber--Determination of zinc content--EDTA titrimetric method》 Related products

GB/T 11203-2001 uses the EDTA Titrimetric method to determine the zinc content in rubber. This standard is suitable for all kinds of rubber samples. The principle is to use EDTA to complexate with zinc to determine the zinc content. The standard specifies the required instruments, such as Burette, etc., and specifies the selection and preparation of reagents. Detailed treatment steps for rubber samples, including dissolving and removing interfering components. At the same time, the titration operation process is standardized, such as the addition speed of titrant, the control of the reaction pH value and the method of end point judgment. According to this standard, the zinc content in rubber can be accurately determined, providing key data support for rubber product quality control and performance optimization.
