Analysis plan
The analysis plan should include the following contents:
Review the description of the situation when the beer bottle exploded: splice and restore the fragments of the exploded beer bottle and number the fragments; observe the distribution area and position of the exploded fragments in the beer bottle: find the burst source according to the burst position;
Check the stress characteristics of the cross section of the fragments of the burst source; check whether the burst source and other fragments have defects: measure the thickness and thickness ratio of the fragments around the burst source; determine whether to conduct a component analysis test on the fragments; determine whether to measure the component uniformity of the fragments; determine whether to conduct a simulation test on the stress characteristics of the fragments; whether to test other factors that need to be determined. DB37/T1270-2009
7 Analysis requirements
7.1 Number the fragments of the burst beer bottle according to the position and splice and glue them back according to the original bottle shape. 7.2 Preliminary analysis
7.2.1 If the fragments are not lost and can be completely restored, the burst beer bottle can be analyzed. 7.2.2 If the fragments are lost and can be basically restored, the main features are retained, and the burst beer bottle can be analyzed. DB37/T1270-2009
7.2.3 If a large number of fragments are lost, the main features are not retained, and they can basically not be restored, the burst beer bottle cannot be analyzed. 7.3 Find the source of the explosion based on the characteristics and distribution of the fragments; and determine its location in the beer bottle. 7.4 Check the stress characteristics of the fragments at the source of the explosion and whether the fragments have major defects such as stones, cracks, bubbles, etc. 7.5 The stress characteristics of the fragments are mainly used to determine whether it is an external force or an internal force. 7.5.1 When subjected to external force, the fracture surface of the glass fragments has obvious inward stress stripe characteristics and cross-sectional characteristics. 7.5.2 When subjected to internal force, the fracture surface of the glass fragments has obvious outward stress stripe characteristics and cross-sectional characteristics. 7.6 Characteristics of bursting fragments
7.6.1 When a beer bottle bursts under external force while being filled with beer and under pressure, the glass fragments show the characteristics of a large number of blocks and some strips.
7.6.2 When a beer bottle bursts due to excessive internal pressure while being filled with beer and under pressure, the glass fragments show the characteristics of multiple strips and radial shapes.
7.6.3 When a beer bottle bursts due to thermal shock force while being filled with beer and under pressure, the bottle bursts along a circle, and then a single crack develops, extending upward along the bottle wall, sometimes accompanied by strip characteristics. 7.6.4 If a beer bottle bursts under mixed forces while being filled with beer and under pressure, the glass fragments have the combined characteristics of 7.6.1, 7.6.2, and 7.6.3, but the characteristics of the main force are still obvious. 8 Test methods
8.1 Thickness measurement
Use a thickness gauge with an accuracy of 0.01mm to measure the thickness of the fragments around the burst source. The thickness and thickness ratio shall comply with the requirements of GB4544. 8.2 Stress test of beer bottle fragments
Perform according to the test method of GB/T4545, and the stress value shall comply with the requirements of GB4544. 8.3 Simulation test of internal pressure resistance of beer bottles
According to the test method of GB/T4546, use a device with a speed of 0.4±0.1MPa/s (4±1bar/s) to make the liquid pressure reach a predetermined value, increase the test pressure of the beer bottles of the same specifications and models in the simulation test until the bottle bursts, and observe the characteristics of its burst fragments. 8.4 Simulation test of impact resistance of beer bottles
Use a pendulum impact instrument, place the beer bottles of the same specifications and models in the simulation test in the pendulum impact instrument, simulate the impact test at the burst source, continuously increase the impact energy until the bottle cracks, and observe the characteristics of its burst fragments. The test method is in accordance with GB/T6552. 8.5 The equipment for the simulation test of thermal shock resistance and thermal shock durability of beer bottles should be equipped with a cold water tank, a hot water tank, and a thermostat to ensure that the low temperature range is 22 ± 5 ° C, the high temperature is stable at ± 1 ° C, and the hot water tank has a heater and is controllable. Observe the bursting characteristics of beer bottles of the same specifications and models after the simulation test. The test method is in accordance with the GB/T4547 test method. 8.6 Analysis of the components of burst beer bottles
Based on the fragments, the main component analysis test of the beer bottle can be carried out, and the main components are Na20, Si02, and Ca0. The test method is carried out in accordance with GB/T1347 standard. Based on the components, it can be analyzed whether the main components of the beer bottle itself meet the reasonable formula requirements of the beer bottle components. 8.7 Measurement of uniformity of burst beer bottles
Based on the fragments of the beer bottle, the uniformity of the glass can be measured. For beer bottles of the same batch and the same material, the glass uniformity is tested by scanning electron microscope after ring cutting; or the structural components of the processed fragment samples are scanned to analyze their uniformity, and then analyzed and compared. 3

9.1 Conclusion
9.1.1 There are defects in the bottle
DB37/T1270-2009
9.1.1.1 The quality of the beer bottle itself has certain defects, and it is also burst by some external force. 9.1.1.2 The quality of the beer bottle itself has no defects, and it is completely burst by external force. 9.1.1.3 The quality of the beer bottle itself has certain defects, and for some reason, the pressure inside the bottle is too great, causing the bottle to burst. 9.1.2 There are no defects in the bottle
9.1.2.1 The quality of the beer bottle itself has no defects, and it is completely burst by some reason that the pressure inside the bottle exceeds the normal pressure that the bottle can withstand.
9.1.2.2 The beer bottle itself has certain quality defects, and the internal pressure exceeds the normal pressure that the bottle can withstand. At this time, it encounters external force, resulting in explosion.
9.1.2.3 The beer bottle itself has no quality defects, but the internal pressure is too high, and it bursts due to external force. 10
