Appearance method GB/T 457.1992.ISO 2236:
/T 4857.22005,ISO 2253:2000,When one of the three test methods is used, the test sample is placed on a flat horizontal surface and the load is applied to its surface. The applied load, atmospheric conditions, time of application and the placement of the test sample are set in advance. Note that if repeated, the upper and lower parts of the test sample are measured. 5 Test settings
5.1 Horizontal surface
The horizontal surface shall be flat (the difference in height between the highest point and the lowest point shall not exceed 2 m). If it is a pool surface: its thickness shall be not less than 150 m.
5.2 Loading methods
5.2.1 Method 1: Package group
Each package in the group shall be identical to the test product under test. The number of packages shall be such that their total mass reaches the appropriate load.
5.2.2 Method 2: Free loading plate
The plate shall be able to adjust itself to the test sample together with the appropriate load. The load and the loading plate may be an integral part of GB/T 4857.3-2C08/1502234:2000.
The center of the loading plate is placed at the center of the top of the test sample and its size shall be at least 10 mm larger than the top surface of the package on each side. The plate shall be strong enough not to deform under the full load. This type of load is also called "free load". 5.2.3 Method 3: Guided loading plate
Guided means can be used to ensure that the false load can always be kept horizontal together with an appropriate load. The plate should be placed on the top of the test sample. Its dimensions should be at least 200mm larger than the top of the test sample. The plate should be strong enough not to deform under full load. Note 1: It is sometimes called "early" loading. Note 2: The rack should be cleared to ensure that the loading level is maintained. The obstacles should not cause friction that affects the test results. 5.3 Deviation The tilt test method (if necessary) should be accurate to the nearest ten thousandths of a degree, and should be able to measure the increase or decrease in the tilt dimension of the system. In addition, the tilt test equipment should comply with the requirements and specifications of Chapter 8.
5.4 Safety facilities
The stability and safety of the load on the test equipment depends not only on the deformation resistance of the test product, but also on the friction between the hair and the bottom of the loading plate. For this purpose, a set of reliable test facilities should be provided, and in the event of a danger, the load should be controlled to prevent the upper and lower parts from being damaged. 6 Preparation of test samples
Put the pre-packed material into the test sample and repack the package according to the normal loading procedure at the time of shipment: if the simulated contents are used, their size and physical properties should be as close as possible to the size and physical properties of the test contents. In addition, the repacking method should be similar to the method used for shipment.
7 Temperature pretreatment of test samples
Pre-treat the test samples under certain conditions according to the requirements of GB/T4857.2. 8 Test procedure|| tt||8.1 The test shall be conducted under the same temperature conditions as the pre-treatment cabinet, and the temperature conditions are selected according to the material or use of the test sample. If the same conditions cannot be achieved, the test shall be conducted under the most similar atmospheric conditions. 8.2 Place the test sample on a horizontal plane (see 5.1) in the predetermined state, and place the loading package assembly (see 5.2.1), the self-loading sub-plate (see 5.2.2) or the guide loading plate (see 5.2.3) in the center of the test sample. If 5.2.2 is used, 5.2.According to method 3, without impact, place the object to be excited on the load plate, and evenly press it against the load plate, so that the center of the load is at the center of the top surface of the test sample. The total mass of the weight and the load plate should be within ±2 mm of the set value. The distance between the load center and the top of the load plate should not exceed 50 mm of the test sample height. If the test sample is not measured according to method 5.2.2 or 5.2.3, the test sample trace should be measured. The test sample should be fully preloaded before the load is applied to ensure that the load plate is in full contact with the test product. 8.3 The load should be maintained for a predetermined duration (usually 24 hours, depending on the material) or until the package is crushed. 8.4 Remove the load and inspect the test product. Note: During the test, if necessary, the dimensions of the test product can be measured in reverse order. Method 2: If the test is special, the appropriate mold can be placed above or below the test product, or it can be placed up and down as needed. Note: The test sample can be placed on a pallet or in a dimensional code state. The most suitable test obstacles should be selected for testing or use Use the actual test form to select the test. The test report should include the following content: a) Description or test system according to this part; c) Laboratory name and address, customer name and address; c) Report identification; List of test samples received and number of test completions and contact information; Name, title and signature of the customer; e) Description of the test results: The test results are valid for the test products; without laboratory certification, this part of the report is invalid; h) Number of test products: GB/T 4857.3—2008/1SO 2234:2000 Detailed description: Name, size, structure and material specifications of the packaging container, support, fixing method, sealing state and its protective measures, total mass of the test product and the mass of the contents, in gram (kg); i
Name, size, number, etc. of the contents. If the contents are simulated, the temperature at the neck, relative humidity and relative humidity of the test chamber, relative humidity of the test chamber, etc. should be specified in detail. These data should comply with the requirements of GB/14857.2;
The marking method specified in GP/T4857.1 should be used according to the state of the test sample during the test; m) Total mass [in grams (kg), the mass of the package or loading surface] The duration of the load on the sample, the method used, i.e., method 1, method 2 or method 3, whether a deflection device is used, the method used, the amount of deflection at the point of the test sample and at what stage of the test are these deflection measurements carried out; the shape and dimensions of the test chamber; a description of the test equipment; any deviations from the test method used and this standard; a record of the test results, and any phenomena observed to help the operator to confirm the test results.
