1. When sampling from storage tanks for liquid chemical products, sampling is taken from ( ). 2. Errors may occur when writing original records, but they must be corrected using the prescribed method, that is, ( ) and then write the correct number above it. 3. Sample retention means keeping the samples ( ) in place; these samples constitute the ( ) records for the quality control department, and they also serve as a basis for the quality control department to maintain ( ).
2. Draw a horizontal line over the original number to keep the originally recorded number clearly visible
Three locations, upper, middle, and lower, should be selected for sampling
1. Upper, Middle, Lower 2. Agree with the answer given above 3. Seal and use the original quality report for judgment
1. Upper, middle, lower 2. Draw a horizontal line over the original number 3. Seal; determine based on the original quality report

Introduction: GB-T 6680-2003, General Rules for Sampling of Liquid Chemical Products, contains detailed regulations regarding liquid sampling. The Quality Management Standards for Laboratories Conducting Drug Testing (Trial Version) provides detailed guidelines on the preparation of test records and test reports, as well as rules regarding sample retention
The upper, middle, and lower sections are sampled using specialized samplers. 2. Draw a horizontal line over the original number; the original number must still be visible. 3. Seal and use the original quality report for evaluation
The upper, middle, and lower sections are handled using specialized samplers: a horizontal line is drawn over the original figure, and the name of the person who made the modification is written next to it; the original quality report is then sealed for evaluation
1. Upper, middle, and lower positions 2. Draw a horizontal line over the original number 3. Seal and evaluate based on the original quality report
1. The upper, middle, and lower sections of the liquid inside the tank. 2. Draw a horizontal line across the original number as a marker; the original number must still be visible. 3. Seal it and use the original quality report for evaluation
