How does the incline impact tester test the transport package? incline impact tester in the packaging industry is very widely used, may some users are not very clear how to operate, now, Haida in this for everyone to introduce the principle and testing methods.
1. incline impact tester application
1) This standard provides the test principle, test equipment (impact testing machine) and test procedure of controllable horizontal impact test for transporting package.
2 This standard is applicable to the evaluation of the transport package can withstand the level of impact and packaging in-house protection. It can be used as a single test or as part of a series of packaging tests.
2. Test principle of incline impact tester
In order to make the test samples in a predetermined state, with a certain impact speed impact, through the Pulse program device to produce the necessary impact pulse.
3. Test equipment
incline impact tester
The incline impact tester used in this test is composed of rail road, trolley, impact surface and pulse program device.
The flat size of the table is enough to meet the requirements of the test samples.
The countertop must have a clapboard, the clapboard and the mesa perpendicular. The countertop and the clapboard remain rigid during the test.
the size of the surface of the clapboard contacting the test sample is larger than the size of the sample impacted part.
should be fitted with steel wheels, its diameter is not less than $number mm, at any time to keep clean, rolling good.
shall be fitted with an automatic release device and be used in conjunction with the traction mechanism so that the trolley can be released anywhere on the slant.
take appropriate measures to make the test samples and the trolley from static to impact before the movement of the relative movement. But in the impact, the test sample relative to the trolley should be able to move freely.
5. Impact surface
The impact surface should be located at the lowest end of the track, and its impact surfaces are 90°±1° with the orbital.
The impact surface should be flat and have enough hardness, on the surface of any square centimeter of the area to withstand 1568N (160KGF) load, the deformation should be less than 0. 25mm.
The structure of the fixed impact surface should be of sufficient strength, the impact must not have obvious displacement.
The structure frame of the fixed impact surface should be fitted with the braking device to prevent two shocks of the trolley.
Pulse Program Device
The diaphragm or impact surface shall be fitted with a pulse program device, which is in the form of hydraulic, spring or cushioning materials.
6. Test procedure
Preparation of test samples
Connect GB 4857. 1 Requirements prepare test samples.
The number of parts of the test sample
The requirements of GB 3538 are numbered for each part of the test sample.
pretreatment of test samples
Press GB 4857. 2 Requirements A condition was selected for temperature and humidity pretreatment of test specimens.
7. temperature and humidity conditions during the test
The temperature and humidity conditions in the test site should be as close to the temperature and humidity conditions as the pretreatment, or within 5 min of the test sample leaving the pretreatment condition.
8. Test steps of incline impact tester
1 record the temperature and relative humidity of the test site during the test.
2 The test sample is placed in the axial center position of the trolley or plate, and the face or edge of the impact is stabilized against the clapboard.
3 The angle between the impact surface and the clapboard should not be greater than 2 ° when the test specimen is carried out.
4 The angle between the impact edge and the baffle plate should not be 2° when the test sample is carried out in the edge. If the test sample is parallelepiped, the angle between one surface of the two sides of the prism and the clapboard surface shall be the predetermined angle, and the angular error is not much less than that of ±5°. or within ± 10% of the predetermined angle (whichever is larger).
5 According to the required impact acceleration value, shock wave shape and duration Select the appropriate pulse program device, according to the predetermined impact speed. The impact velocity error should not be greater than the ±5% of the predetermined horizontal impact velocity.
6 after the test, according to the relevant standards to check the packaging and the damage of the inside. The results are analyzed.
9. Test Report
1, the number of test samples;
2. Detailing the external dimensions, structure and material specifications of the packaging container;
3, the name of the interior, specifications, models, quantities, performance, such as the use of analog objects to be explained;
4, the test sample of the quality of the inside, in kilograms;
5, the temperature of pretreatment, relative humidity and time;
6. Temperature and relative humidity of the test site;
7, test equipment, type;
8, the test sample of the predetermined state;
9, test samples, test sequence and test times;
10, impact speed, impact acceleration, shock wave shape, pulse duration and the check-back load device and the friction of the table;
11. Pulse program Device;
12, record the test results, and put forward the analysis report;
13. Explain the difference between the test method and the standard;
How does the incline impact tester test the transport package? The above is the transport package of a test method, I do not know if you have learned? The user learns the bevel impact test machine, has the vital function to the service life and the test precision.
