19、er bodies). The work of preparing International Standards is normally carried out through ISO technical committees. Each member body interested in a subject for which a technical committee has been established has the right to be represented on that committee. International organizations, government

20、al and non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization. International Standards are drafted in accordance with the rules given in the ISO/IEC Direct

21、ives, Part 3. Draft International Standards adopted by the technical committees are circulated to the member bodies for voting. Publication as an International Standard requires approval by at least 75 % of the member bodies casting a vote. Attention is drawn to the possibility that some of the elem

22、ents of this International Standard may be the subject of patent rights. ISO shall not be held responsible for identifying any or all such patent rights.

25、s using a variable frequency 1 Scope This International Standard specifies two methods for carrying out a sinusoidal vibration test on a complete, filled transport package or unit load using a variable frequency. These tests may be used to assess the performance of a package or an unit load in terms

26、 of its strength or the protection that it offers to its contents when it is subjected to vertical vibration. Each may be performed either as a single test to investigate the effects of vertical vibration or as part of a sequence of tests designed to measure the ability of a package or unit load to

27、withstand a distribution system that includes a vibration hazard. 2 Normative references The following normative documents contain provisions which, through reference in this text, constitute provisions of this International Standard. For dated references, subsequent amendments to, or revisions of,

28、any of these publications do not apply. However, parties to agreements based on this International Standard are encouraged to investigate the possibility of applying the most recent editions of the normative documents indicated below. For undated references, the latest edition of the normative docum

29、ent referred to applies. Members of ISO and IEC maintain registers of currently valid International Standards.

30、. ISO 2234, Packaging Complete, filled transport packages and unit loads Stacking tests using static load. 3 Term and definition For the purposes of this International Standard, the following term and definition applies. 3.1 test item a complete, filled transport package or unit load 4P r i n c i p

31、l e The test item is placed on a vibration table and vibrated at a frequency which varies at a constant logarithmic sweep rate between 3 Hz and 100 Hz, which may be followed by vibration between 10 % of the principal resonant frequencies within the range from 3 Hz to 100 Hz. The atmospheric conditio

32、ns, the duration of the test, the peak acceleration, the attitude of the test item and its method of restraint are predetermined. NOTE When required, a load may be superimposed on the test item to simulate conditions at the bottom of a stack. ENISO8318:20021ISO 8138:(0002)E 2 ISO 0002 All irhgts ser

33、edevr 5 Apparatus 5.1 Vibration table 5.1.1 The vibration table shall be of sufficient size, rigidity and mass-carrying capacity, supported on a mechanism that will maintain the surface horizontal during vibration. 5.1.2 The table shall be horizontal within a maximum angular deviation of 0,3. 5.1.3

34、The apparatus shall meet the requirements and tolerances of clause 8. NOTE The table may be equipped with: a) low fences to restrict sideways and endwise movement during testing; b) high fences or other means of maintaining a superimposed load in position on the test item during testing; c) means to

35、 simulate the method of restraining the test item during transit. 5.2 Instrumentation The instrumentation shall comprise accelerometers, signal conditioners and data display or storage devices to measure and control the accelerations at the test surface. The instrumentation system shall have a respo

36、nse accurate to within 5 % over the frequency range specified for the test. NOTE Instrumentation may also be desirable for monitoring the response of the containers and packaged items. Sensors may be used to record velocities, amplitudes and frequencies of the contents in relation to the forcing vib

37、ration from the vibration table and possibly those on the outer surfaces of the package. 6 Test item preparation Fill the test item with its intended contents and ensure that the test item is closed normally, as if ready for distribution. NOTE Simulated or substitute contents may be used on conditio

38、n that the dimensions and physical properties of such contents are as close as possible to those of the intended contents. However, the closure should be the same as for distribution. 7 Conditioning The test item shall be conditioned in accordance with one of the conditions described in ISO 2233. 8

39、Procedure 8.1 General Wherever possible the test shall be carried out in atmospheric conditions identical to those used for conditioning, and particularly where this is critical to the materials or application of the test item. In other circumstances, the test shall be carried out in atmospheric con

40、ditions which approximate those used for conditioning as closely as is practicable. ENISO8318:20022ISO 8138:(0002)E ISO 0002 All irhgts seredevr 3 8.2 Method 1 8.2.1 Place the test item in the predetermined attitude on the vibration table (see 5.1). If the positioning of the test item on the platen

41、of the vibration table changes the vibration movement, the vertical projection of the centre of gravity of the test item shall be as near as practicable to the geometrical centre of the platen of the vibration table; if the test item is not secured to the table it may be fenced. If a superimposed lo

42、ad is required, the loading procedure shall comply with ISO 2234. 8.2.2 Subject the test item during a predetermined test duration to a predetermined vertical sinusoidal vibration with a frequency varying up and down between 3 Hz and 100 Hz at a sweep rate of 0,5 octave/min. 8.2.3 The acceleration s

43、hall be measured with an accelerometer which is attached to the table as close as possible to the test item, but protected so that it will not be contacted by it. 8.2.4 In the event of a horizontal frequency component being present, its acceleration shall not exceed 20 % of the value for the vertica

44、l component. 8.3 Method 2 8.3.1 Perform a resonance search test over one or more complete sweep cycles applying a suitable lower level of acceleration, typically in the range of 0,2 g to 0,5 g, and record the accelerations measured on the test item and on the table. 8.3.2 Determine the most severe a

45、nd critical resonances, typically up to three. 8.3.3 Perform the endurance test at one of the defined resonances by sweeping over a frequency range varying between 10 % of the defined resonance frequencies. Repeat this procedure for other selected severe or critical resonances by applying a suitable

46、 acceleration for a predetermined duration. NOTE For the duration of the tests the various resonances may be tested for different durations. 9 Test report The test report shall include: a) a reference to this International Standard; b) the name and address of testing laboratory and name and address

47、of the customer; c) the unique identification of the report; d) the date of receipt of the test items and the date(s) of performance of the test; e) the name, title and signature of persons accepting test responsibility for the test report; f) a statement to the effect that the test results relate o

48、nly to the items tested; g) a statement that the report shall not be reproduced except in full without the written approval of the testing laboratory; h) the number of replicate test items tested; i) a full description, including dimensions, structural and material specifications of the test item and its fittings, cushioning, blocking, closu
