The storage time of used products is generally no more than 2 months (close the bottle cap immediately after pouring out the solution); 0.01 mol/L potassium hydroxide standard titration solution The concentration should be within the range of ±0.5% of the specified concentration; 0.01 mol/L aqueous potassium hydroxide standard titration solution at 25°C or below The maximum storage time should not exceed 30 days (close the bottle cap immediately after pouring out the solution). If the storage conditions do not meet the requirements, prepare it before use. 0.01mol/L ethanol solvent potassium hydroxide standard titration solution should be prepared before use; when a standard titration solution other than that specified in this document is required In any case, if the standard solution becomes turbid, precipitates, changes color, etc., it should be immediately diluted. Stop using, re-prepare and recalibrate. 4.3 The ambient temperature during the measurement process should be controlled between 15℃ and 25℃. 4.4 After the sample is ground, it should be extracted with the extraction solution as soon as possible. The ground sample should not be left for more than 2 hours. Titration. If titration fails in time, the separated extract should be sealed and placed in a 4℃ refrigerator for no more than 24h. 4.5 Grains with a moisture content above 18% should be pre-dried according to the double drying method of GB/T 5497 before being milled. ......Tips & Frequently Asked Questions:Question 1: How long will the true-PDF of GB/T 5510-2024_English be delivered?Answer: Upon your order, we will start to translate GB/T 5510-2024_English as soon as possible, and keep you informed of the progress.
