This test method is to determine the sleep rate of a product under the influence of a small impact force. The test method uses a controlled impact material to control the impact transmitted to the product. The sleep value obtained in this test or verification can be used in the product packaging and product design. 1 Test equipment
The test equipment can be equipped with ready-made color parts to make them fall under the expected impact. The impact material can comply with the specification. The product can be connected to a
1. 2 The impact surface
The non-combustible water tank is a water tank with a small amount of material. The test sample is a special test system with a speed analyzer, a large analyzer and a display. The product is required to display the acceleration time in the standard
test with an adaptive acceleration time. The product must not show overload phenomenon. The test system should generally be 1-100% and the complete failure frequency should be no less than 100-100Hz. The resolution of the test system is within 5.
2 Packaging containers and cushioning materials
This method requires the correct external packaging containers and cushioning materials: 2.1 The external packaging containers and cushioning materials that are not manufactured by the manufacturer can also be used. 2.2 It can also be required that: the external packaging containers and cushioning materials that are used to package the test products can be used. 2.2.1 The external color of the crystal and cushioning materials should be able to meet the test requirements. 2.2.2 The original elastic or plastic materials with a length of 10~25m are used. If the test is repeated, the lining of the line is prohibited to prevent the raw materials from being used.
3 Test samples
The test unit is in control of the product title. When the product is in control, it is allowed to use defective products that do not affect the "quality certification value" for quality inspection. Before the test, it is necessary to use other products that do not affect the quality certification value. The sample is not required to be tested.
4 Test sequence
4.1 Package test sample No.
National standard approved on August 24, 1987
Implementation on March 1, 1989
GB 81T1--87
According to: 3533-83 "Price List of Risks" for packaging. The various specifications of the test samples shall be marked according to the same method.
4.2 External treatment
Before the test, according to GB 7.2 "Temperature and humidity adjustment of transport packaging", a soft material shall be used for packaging, punching and test products:
Humidity conditions during the test
Test brand and pretreatment time The same temperature and humidity conditions are selected. If the same conditions are not achieved, the test must be started just after 5 minutes of treatment under the test conditions.
4.4 Test steps
4.1 Impact speed
According to the actual transmission environment conditions: (such as installation temperature, etc.), select the impact speed. The typical impact speed is selected in the equivalent range of 45~0
. 4, 42 can be selected before||t If it is known that the product is always subject to stress during transportation, then a similar test is required: if the direction is uncertain, select a direction for testing. 4.48 Installation of the acceleration sensor belt
The acceleration sensor should be installed on the rigid foundation of the product when it is close to the impact, and the assembly must make it feel the axis of the impact.
4, 4.4 Installation test sample!
The test sample and the track piece should be placed in the state of the micro-environment according to the market. In the case of the device. During the impact of the test product, the impact force should be greater than that of the impact force before the first impact occurs. Use the same material to impact the other test samples, and then impact the entire test time.
4.4,5 The current detection test instrument and the test instrument are required to obtain the accurate pulse acceleration for a certain period of time. 4.6 Put the buffered product in the test plan and conduct the "second impact test". Note that the impact should be less than that of the first impact. 4.4.7 After the initial impact, the test sample is unpacked and the test product is inspected to determine whether damage has occurred. 4,4.8 Repack the test product
If the test sample is not fully assembled, the following method shall be used for the new packaging test sample. 1. Reduce the thickness of the edge of the test sample in the impact direction, and move the reduced cushion to the top (the cushion block should be added according to the test product selection) to ensure that the total strength of the impact material in the packaging remains unchanged. Avoid the test sample touching the bottom during the negative test.
b, cut the new package according to the original packaging state. 4.4.9 Heavy crown state impact reduction test
Lu large net impact strength, change the first paragraph: 4.6 to the first paragraph +.1.8 step, and the room test sample is damaged. There are two methods for the intensity of the pressure,
a. When the pressure is used in the packaging of the method of 1.1.B, the height of the European tour is changed, b, the method of the package of the method of 1.4.B is used, and the greater impact strength is produced, which will definitely have a greater drop point. But this method can lead to a relatively close decision. After the first test, the packaging release device or cushioning material will not be able to take the product. The packaging release device or cushioning material must be replaced. 4.10 Determine the value of the test sample. Take the maximum flow rate of the bottle failure at the time of the test. Use packaging materials and packaging structures similar to those in this test for the product. GB81T1: The non-standard packaging used in the test is not available for the supply of the product. 4.4.1 Conduct the active currency test of the specified party. If it is necessary to conduct the test on the opening force of the store, the goods shall be tested from paragraphs 1..2 to paragraph 4. 5 Test announcement. Test shore first seat live doctor military military test sample. The test sample is good and suitable for the package, type, production, and period! Days and before, etc., test sample number:
