5.3 Measuring method for volume of sales package
5.3.1 Method I Instrument method (arbitration method)
Calibrate the volume measuring instrument under normal temperature and pressure according to the instrument operation rules, then put the sales package on the instrument measuring platform and start the measurement procedures to measure the sales package for 3 times, and take the mean to calculate the volume of sales package.
5.3.2 Method II Manual method
For cuboid sales package, measure the length, width and height along the outer wall of package for 3 times with length measuring instrument under normal temperature and pressure, and take the mean to calculate the volume of product sales package; for cylindrical sales package, measure the package along the outer wall for 3 times with length measuring instrument, and take the mean to calculate the volume of product sales package.
Note: It is only applicable to sales packages with regular shapes.
5.3.3 Method III Other methods
When drainage method or similar method is used for measuring the volume of product sales package, immerse the sales package in a container, in which the volume of water (or other even fine particles) has been accurately measured, under normal temperature and pressure, and the increased volume is the volume of product sales package, measure for 3 times, and take the mean as the volume of product sales package.
Note: Drainage method is only applicable to waterproof sales package.
