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 other cr
6、iteria 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, but
7、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 approved th

If testing is performed with pre-release hardware and changes occur prior to release, the changes shall be analyzed to determine if they may reasonably impact the outcome of the tests. If a significant impact is indicated, the testing shall be repeated on released hard
18、ware. NOTE: It is recommended that exposure to criteria is done consecutively without functional verification or opening of the packaging after initial functional verification and physical inspection has been completed. All samples shall be ATIS-0600010.02.2012 4 packaged in their normal packaging,
19、including all accessories, operational manuals, cables, etc. More than one test sequence may be required; for example, where a field replaceable unit (FRU) is also shipped in its individual shipping container. The recommended sequence for Baseline criteria is as follows: 1. Functional Verification a
20、nd Physical Inspection: Equipment shall be capable of performing the functionality as defined in the test plan. Functional performance shall be defined and documented during test plan development based on the manufacturers specifications. Input and load conditions shall be chosen to obtain full util
21、ization of the equipment under test (EUT), as detailed in the test plan. The EUT shall be configured in a functional test bed representative of its intended use. It is permitted to use artificial loads to simulate external loads on the equipment to determine proper operation of the EUT during functi
22、onal checks. 2. Packaged Drop. 3. Transportation Vibration. 4. Rail Car Shock Impact (if applicable). 5. Functional Verification and Physical Inspection: The equipments functionality and physical integrity shall be checked at the end of testing. A visual inspection shall be conducted to ensure no ph
23、ysical damage to the product has occurred. See #1 above. 6. Unpackaged Drop. 7. Functional Verification and Physical Inspection: The equipments functionality and physical integrity shall be checked at the end of testing. A visual inspection shall be conducted to ensure no physical damage to the prod
24、uct has occurred. See #1 above. It is recognized that this approach may not allow one to identify the specific cause of a failure. In the case of failure, new equipment must be attained and functional verification shall be performed after each individual stress to identify the failure in question. I
25、f desired, the equipment can be removed from its packaging and functionally verified between individual tests. This shall be documented in the test report. Upon completion of functional verification, where applicable, the equipment shall be placed back in its original packaging to continue the test
26、sequence. Calibration and use of equipment shall be in accordance with ISO/IEC 17025:2005, General Requirements for the Competence of Testing and Calibration Laboratories. Tolerances other than height are specified in individual sections. Unless otherwise specified, for tests that involve height mea
27、surements, maintain tolerances at 20 mm or 10% of the height, whichever is smaller. 5 Equipment Handling Conditions: Packaged Drop 5.1 Category “A” Packaged Communications Equipment Weighing 25 kg, topple restraints may be used for safety purposes, as long as the restraints do not affect the outcome
28、 of the test. Any use of topple restraints shall be noted in the report.

30、rop Surfaces for Packaged Communications Equipment 3. For corner drops, the packaged EUT shall be oriented so that a straight line drawn through the struck corner and the packages geometric center is approximately perpendicular to the impact surface (see Figure 2). Figure 2: Package Orientation for
31、Category “A” Corner Drops 4. Allow sufficient time between drops for the cushioning to recover its shape. 5. Continue the testing until all drops have been completed NOTE: If the container/package is visibly damaged or if the packaged EUT sounds damaged after a drop, stop the testing and inspect the
32、 equipment and check for functionality per Sections 5.1.5.2 and 5.1.5.3. ATIS-0600010.02.2012 8 5.2 Category “B” Packaged Communications Equipment Weighing 220.5 pounds (100 kg) or Palletized Communications Equipment 5.2.1 Description The test parameters for Category B packaged drop are intended to
33、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-trucks, cr
34、anes, 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 be supported from it and allowed to
35、assume the resultant position, as shown in Figure 4. Because the rest face may not be horizontal, the prescribed drop height should be measured from the lowest point on the equipment to the floor. The test area shall be sufficiently large such that the packaged EUT is not precluded from toppling ove

ATIS-0600010.02.2012 10 Figure 3: Category “B” Rest Surface Drop Figure 4: Category “B” Off-Center Drop 6 Transportation Vibration Test Methods Requirement R-7: The packaged EUT shall be tested to the baseline criteria described in Section 6, and shall comply with the applicable conformance crite
37、ria of Section 6. 6.1 Description The test levels and test methods for baseline criteria described in Section 5 are intended to determine the ability of packaged EUT to withstand the vibration environment during transport. The random vibration test parameters provide magnitude, frequency range, dura
38、tion, and direction of vibration that result in the simulation of actual transportation environments. ATIS-0600010.02.2012 11 Compliance to these baseline criteria indicates compliance to all referenced transportation vibration specifications listed in Table 1. 6.2 Test Apparatus however, it is perm
39、issible to reseal the box during the testing so long as it is noted in the report). Requirement R-10: EUT shall not sustain functional degradation after Transportation Vibration testing. ATIS-0600010.02.2012 12 6.5.1 Equipment Operation The EUT shall be non-operational throughout the exposure, but o
40、perational 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 fatigue stresses, testing w
41、ould 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 environmental tests for telecommuni
42、cations equipment; Part 2-2: Specification of environmental tests; Transportation, Test Specification T2.3 - Public Transportation. While higher frequencies may be encountered in some transport modes, testing is restricted to the high energy, low frequency contributions. Perform the test once along
43、each of three (3) mutually perpendicular axes of the equipment. 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) securely on the vibration mac
44、hine. 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 the normal attitude during transportation is specified, then the severity for the horizontal axes is reduced by a factor of 10.
45、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 be exposed to the T
46、ransportation Vibration test in ASTM D 4169 Section 12.4, Random Test Option, Level 1 or Level 2 (Truck and Air) test vibration pattern. This test shall be performed on each of the three mutually perpendicular axes for 1 hour (60 minutes). Testing below 5 Hz is not required. NOTE: The rail ASD (Acce
47、leration Spectral Density) levels are enveloped using the truck and air vibration curve as shown in Figure A-1. 7 Equipment Handling Conditions: Rail Shock Impact Requirement R-11: Packaged EUT weighing more than 200 pounds (91 kg) shall be tested to the baseline criteria described in Section 7, and
48、 shall comply with the applicable conformance criteria of Section 7. This test is not required if it can be demonstrated that the EUT will not be shipped by rail. 7.1 Description The test levels and test methods for baseline criteria described in Section 7 are intended to determine the ability of pa
49、ckaged EUT to withstand the effects of rail car coupling during transport. The rail car shock impact test parameters provide magnitude, duration, and direction of shock that result in the simulation of actual rail car transportation environments. Compliance to these baseline criteria indicates compliance to all referenced rail car shock specifications listed in Table 1.
