This part of GB/T 4857 specifies the main performance requirements, test procedures and test report contents of the test equipment used in the low pressure test of transport packages and single cargo. This part is applicable to the assessment of the ability of transport packages and single cargo in pressurized cabins and non-pressurized cabins of aircraft flying at an altitude not exceeding 3500m to withstand the impact of low pressure and the protection of the contents by the packaging. For ground transport packages and single cargo at higher altitudes, low pressure tests can be carried out with reference to this part.

This part is part 13 of GB/T8=7. This part adopts international standard 1S02373:20000 Packaging inspection - complete, full-scale packaging and unit cargo condition - low-pressure test 3. Compared with GB/47.13:32 Packaging low-pressure test 1502872 standard, the main differences are as follows: Some formats have been expanded and relevant explanatory notes have been reduced.
Since my country has defined relevant technical specifications in packaging technical standards, the relevant technical specifications have been cancelled: "Test for resistance to all parts" is a continuation of the R/T1R7 series standards. The test content has been modified. The changes in the G4 requirements are as follows: In the specification, the original instrumental transport packaging was revised to be suitable for transport packages and unit materials: the original standard small \ atmospheric environment conditions representative "sensitive people Xie to A (information science and technology records). For the convenience of reference; - the relevant units of Europe have revised it according to international standards. 1

Basic tests for packaging for transport
Part 13: Low pressure test method
GB/T4857.13-2005
(This part of GB4857 defines the main requirements for the test equipment used in the low pressure test of the transported packages and the contents of the test report. This part is used to evaluate the ability of other packages and single cargoes in non-pressurized cargo compartments not exceeding the normal cargo height during air transport to withstand the effects of low pressure and the protection of the contents. For packages and unit cargoes transported at a higher altitude, refer to this part for low pressure tests.

Place the test food in the pressure test box! Then reduce the air in the box to the equivalent of 35m3/s. Keep the air pressure at 35m3/s. Maintain the pressure for a predetermined time and return it to normal pressure. If necessary, the pressure should be controlled at the same temperature during this period. Appendix A) 4 Test setup
The pressure test should have enough time to accept the test sample, and the pressure and temperature should be adjusted to meet the requirements of Part 5.1.
