跌落试验标准(Drop test standard)Package drop test standard published: 10-05-05 source: Hits: 1903 field selection: large and smallPackage drop test standardPeople's Republic of China national standardGB/T4857.5-92 instead of GB4857.5-84Method of drop test for packaged transport packagesPackaging-Transport packages-Vertical impacttest method by droppingTransport package drop test in the standard equivalent to the international standard ISO2248-1985 "packaging - complete and filled".1. subject matter and scope:This standard specifies the content of vertical impact testing for performance test equipment, test procedures and test reports for transport packages.This standard is applicable to the evaluation of the protection ability of transport packages under vertical impact the impact strength and packaging of the contents. It can be used as a single test, also can be used as part of a series of experiments.2. reference standard:Marking method of GB/T4857.1 packaging transport packages of various parts of theGB/Y4857.2 packaging transport packages temperature and humidity conditioningThe general principle of GB/T4857.17 packaging transport packages compilation of performance test programThe quantitative data of GB/T4857.18 packaging transport packages for the compilation of performance test3. test principle: filed test samples to a predetermined height, and then make it according to the predetermined state of free fall, collision and impact table.4. test equipment:4.1. impact: impact test table for the horizontal plane, does not move, not deformation, and meet the following requirements:A. is a single object, quality is at least 50 times of test sample quality;B. have a large enough area, to ensure that the test sample falls completely in the impact on the table;The impact of C. in the table any two points on the level of clearance was more than 2mm;The impact of 100mm2 on the table D. in any area under static load of 10kg, the deformation amount shall not exceed 0.1mm.4.2. lifting device: in lifting or descending process, should not damage the test sample.4.3. support device: support device of test samples should be able to make the test sample in the predetermined state required prior to release.4.4. release: in the release of the test sample in the fall, should make the test sample without any part of touch device, ensure the selfDrop by.5. test procedure:5.1. test sample preparation: prepare the test samples according to the requirements of GB/T4857.17.The various parts of the 5.2. test sample number: each part of the test samples are numbered according to the provisions of GB/T4857.1.Pretreatment of 5.3. test sample: according to the provisions of GB/T4857.2, selected a condition of temperature and humidity on the test sample pretreatment.Temperature and humidity conditions in the 5.4. test:The test shall be carried out in the pretreatment with the same conditions of temperature and humidity. If not up to the pretreatment conditions, should be in as far as possible to test pretreatment temperature and humidity conditions.5.5.Test intensity value choice: according to the provisions of GB/T4857.18 test of strength value.5.6 test procedure:5.6.1 filed test samples to the drop height of the required position, and according to a predetermined state will hold. The vertical height and predeterminedThe height difference does not exceed a predetermined level + 2%. Drop height refers to the test sample is ready to release the lowest and the impact of the tableThe distance between.5.6.2 according to the predetermined state, the release of test samples:A. falls, the angle between the drop side and the level of test sample surface maximum of not more than 2 degrees;B. edge drop, the angle between the edge of the South and drop level maximum of not more than 2 degrees, the test sample surface and the impact of regulationsTable error angle not greater than 5 degrees angle or 10% (with larger values prevail), so that the test sample of gravityBy falling edge line;C. angle drop, the test sample set angle error surface and the impact surface is less than 5 or the 10% (with a large angleThe numerical test samples shall prevail), so that the gravity line through the drop angle;D. no matter what the state and shape of the test samples, test samples should be made by the gravity line surface, line, drop point.The actual impact velocity and impact velocity of 5.6.3. free fall when the difference is no more than a free fall of + 1%.5.6.4. after the test according to the relevant standards or regulations to inspect the damage filling packaging and test results are analyzed.6. test report:The contents of the A. name, specification, type and quantity;The number of B. test samples;C. details: name, packing container size, structure and material specifications; accessories, buffer pad, support,fixing method,Sealing, bundling and other protective measures;The quality and the quality of the contents of the D. test samples, in kilograms;E. pretreatment temperature relative humidity and pretreatment time;F. for testing the temperature and relative humidity;G. detailed placement status test samples when testing;Sequence number h. and drop test samples;Drop height I. test samples, in millimeters;The type of equipment used by J. test;K. records of the test results, and observed in the trial in any help to the correct interpretation of test results of the phenomenon;L. it is shown that the difference of the standard and test method;M. test date, test personnel to sign, seal test.。
