e. Metal container performance test
(3) Performance test of transport package
①The test strength is generally expressed by the quantity value, and the corresponding quantity value needs to be determined for each test of the transport package.
a. The temperature and humidity adjustment process needs to determine the temperature, relative humidity, time, pre-drying conditions, etc.
b. The stacking test requires the determination of the load and its duration, temperature, relative humidity, number and condition of the specimen.
c. The vertical impact drop test needs to determine the drop height, number of impacts, temperature, relative humidity, number of samples and state.
d. The horizontal impact test needs to determine the horizontal acceleration, number of impacts, impact surface, additional obstacles, pendulum quality, temperature, relative humidity, sample quantity and state.
e. Sine (fixed frequency, variable frequency) vibration test needs to determine the frequency, acceleration, displacement amplitude, test duration, additional load, temperature, relative humidity, sample quantity and state.
f. The pressure test needs to determine the maximum load (predetermined value), platen moving speed, temperature, relative humidity, sample quantity and state.
g. Low air pressure test needs to determine the air pressure and its duration, temperature, sample quantity and state.
h. The spray test needs to determine the amount of water sprayed and its duration, the number and state of the samples.
i. Rolling tests need to determine the number of rolls, the number of samples and the state.
② Static performance test items
Such as stacking test, pressure test, low pressure test, spray test, etc.
③Dynamic performance test items
Such as impact test, vibration test, rolling test, product vulnerability, etc.
④ Other performance test items
Such as mildew test, moisture test, anticorrosion test, rust test, etc.
The selection of test items should be mainly based on the possible hazards in each link of the circulation process, and according to different test purposes, due consideration should be given to factors such as test equipment conditions, test time, sample quantity, and test costs.
In addition, the test items of the package contents include temperature, humidity, gas composition, physical and chemical properties, etc., but the performance test of the contents does not belong to the research category of packaging testing technology. Appearance inspection, if necessary, functional test may be considered. NBCHAO reminds you: in the process of performance , product vulnerability is an important test item.
