For more information, please visit .AMERICAN NATIONAL STANDARD Approval of an American National Standard requires review by ANSI that the requirements for due process, consensus, and ot

6、her criteria for approval have been met by the standards developer. Consensus is established when, in the judgment of the ANSI Board of Standards Review, substantial agreement has been reached by directly and materially affected interests. Substantial agreement means much more than a simple majority

7、, but not necessarily unanimity. Consensus requires that all views and objections be considered, and that a concerted effort be made towards their resolution. The use of American National Standards is completely voluntary; their existence does not in any respect preclude anyone, whether he has appro

8、ved the standards or not, from manufacturing, marketing, purchasing, or using products, processes, or procedures not conforming to the standards.

33、ded to determine the ability of packaged EUT to withstand the stresses occurring during manual handling, such as loading, unloading, stacking, or sorting. The main stresses of these operations are caused by dropping or impacts from material handling equipment (e.g., forklifts, pallet jacks, hand-tru

34、cks, cranes, etc.). Equipment complying with these baseline criteria is also considered compliant to all referenced packaged drop specifications in Table 1. 5.2.2 Test Apparatus or For packaged EUT designed with handling hardware (e.g., eye bolts, etc.), the unit should besupported from it and allow

35、ed to assume the resultant position, as shown in Figure 4. Because therest face may not be horizontal, the prescribed drop height should be measured from the lowest pointon the equipment to the floor. The test area shall be sufficiently large such that the packaged EUT isnot precluded from toppling

Requirement R-10: EUT shall not sustain functional degradation after Transportation Vibration testing. 12 ATIS-0600010.02.2012(R2017) 6.5.1 Equipment Operation The EUT shall be non-operational through

40、out the exposure, but operational during functional checks. See Section 4. 6.5.2 Equipment Failures Any non-compliance requires a root-cause analysis to determine the reason or cause of said failure. In the case of any non-compliance to Requirement R-8 through Requirement R-10, due to low-cycle fati

41、gue stresses, testing would need to be repeated for all three mutually perpendicular axes. In the event of a failure, good engineering judgment should be exercised to determine which tests would need to be repeated. 6.5.3 Functional and Physical Requirements Environmental conditions and environmenta

NOTE: If the transportation vibration exposure has been performed in accordance with Annex A, it is considered compliant to Section 6. 1. Mount the packaged EUT (resting on its normal shipping base or side) secure

44、ly on the vibration machine.2. Measure the input acceleration with a suitable transducer.3. Subject the package to the prescribed random vibration per Table 3. For palletized containers, where thenormal attitude during transportation is specified, then the severity for the horizontal axes is reduced

45、 by a factor of 10. 4. Subject the package to the prescribed random vibration for 30 minutes in each test axis.5. Inspect the equipment for physical damage and verify operation following the vibration testing.As an acceptable alternative to performing the test described above, the packaged EUT can b
