Test Setup. 4.1. The vehicle test setup is based on the laboratory type setup as described in paragraph 7.2. of IEC 00000-0-0: 2nd edition, 2004.
4.2. The vehicle shall be placed directly on the ground plane.
4.3. The Technical Service shall perform the test as specified in paragraph 7.7.2.1. Alternatively, if the manufacturer provides measurement from a test laboratory accredited to the applicable parts of ISO 17025 (second edition 2005 and Corrigendum: 2006) and recognized by the Approval Authority, the Technical Service may choose not to perform the test to confirm that the vehicle meets the requirements of this annex.
Test Setup a. Power Supply DOE proposes that section 3.1 of IES LM–79–2008 be incorporated by reference to specify requirements for both alternating current (AC) and direct current (DC) power supplies. This section specifies that an AC power supply should have a sinusoidal voltage waveshape at the input frequency required by the LED lamp such that the root mean square (RMS) 24 summation of the harmonic components does not exceed three percent of the fundamental frequency 25 while operating the LED lamp. Section 3.2 of IES LM–79–2008 also requires that the voltage of an AC power supply (RMS voltage) or DC power supply (instantaneous voltage) applied to the LED lamp should be within ± 0.2 percent. These requirements are achievable with minimal testing burden and provide reasonable stringency in terms of power quality based on their similarity to voltage tolerance requirements for testing of other lamp types. These requirements ensure that the power supplied to the LED lamps is consistent and, in combination with other specifications, would likely result in repeatable photometric measurements.
b. Lamp Mounting and Orientation DOE proposes that the LED lamp be mounted as specified in section 2.3 of IES LM–79–2008 and be positioned in the base-up, base-down, and horizontal orientations for testing. Section 2.3 of IES LM–79–2008 requires that the LED lamp should be mounted to the measuring instrument (integrating sphere or goniophotometer as described in section III.B.4.c) in such a manner that the heat flow through supporting objects does not affect the measurement results. This is important because the lumen output of LED lamps is sensitive to thermal changes. DOE’s view is that 23 ‘‘IES Approved Method for the Electrical and Photometric Measurement of Fluorescent Lamps.’’ Approved January 31, 2009. 24 Root mean square (RMS) voltage/current is a statistical measure of the magnitude of a voltage/ current signal. RMS voltage/current is equal to the square root of the mean of all squared instantaneous voltages/currents over one complete cycle of the the examples specified in section 2.3 of IES LM–79–2008 (such as suspending a ceiling-mounted LED lamp in open air and using support materials such as Teflon that have low heat conductivity instead of mounting it in close thermal contact with the sphere wall) ensure negligible cooling effects through the supporting objects of the LED lamps and minimal disturbance of the air flow around the lamp. DOE proposes that these materials...
Test Setup. All tests shall be performed using test vehicles equipped with a calibrated test mobile(s) that meet or exceed the minimum performance specifications (TIA/EIA IS-136 and IS-137) for a TDMA mobile subscriber unit. Test mobiles shall have fixed attenuators connected between the transceiver and antenna to compensate for the test setup. The compensation shall be computed to render the test data equivalent to that which would be obtained with an operational subscriber unit under common conditions (e.g., attenuation shall be added in order to compensate for the benefit offered by the additional gain and height of the test vehicle antenna.). The values of any attenuators shall be mutually agreed upon and determined via calibration procedure. No attenuators shall be added into the mobile path to compensate for vehicle or building penetration losses. The net value of attenuation used shall take into account the cable loss from test vehicle antenna to test unit, as this loss would not present in an operational subscriber unit under common conditions.
Test Setup. This section is mainly related on the capability of the MAENAD language and tools to support test engineers for the setup of experiments. The focus is a gap analysis to derive plug-in that support the semi-automatic setup of an instrumented test. Automatic generation of networks related setup Plug in to automatically derive the information needed to setup network communications and interpretations of network data. This includes for each network signals: endianism, length, start bit, factors to obtain the physical value, message packing The concrete network setup is defined in AUTOSAR and Fibex standards and not within the scope of EAST-ADL. Extraction of subsystem test sets Plug in to automatically derive test vector related to the subsystem under analysis Implementation possible due to the hierarchical organization of the model and the capability of the model to link architectural elements and their dependencies
Test Setup xxx108 A better alternative is to use a low voltage range DC Power Supply in series with the AC power source output. Since most DC Supplies are uni-polar, a polarity reversal relay may be used to change polarity or the connection terminals can be swapped as needed. To electrically remove the DC Power Supplies when not in use, a bypass relay can be used as shown – as long as the output of the DC Supply is off. It is important that both positive and negative output terminal of the DC Power Supply used are floating (NOT grounded) as the DC supply will be floating on the AC output. Also, isolation between the DC Supplies output terminals and chassis must be higher than 120Vrms. NOTE: Check with the manufacturer of the DC Power Supplies used what the maximum AC Ripple Current rating of the bulk output capacitors is as these caps will see the UUT AC load current in addition to any DC current drawn by the UUT. The relevant test setup for three phase UUT’s is shown in Figure 9. For single phase applications, only one DC supply is needed on the Phase A output of the AC Power Source.

Test Setup. Three types of tests were performed to verify the system: scenario tests, integra- tion tests, and unit tests. This section first describes the scenarios used, and then for the points above describes which tests were performed to verify each of them.
Test Setup. A test pit is dug at site up to the depth at which the foundation is proposed to be laid. The width of the pit should be at least 5 times the width of the test plate. At the centre of the pit a small square depression or hole is made whose size is equal to the size of the test plate and bottom level of which corresponds to the level of actual foundation. The depth of the hole should be such that the ratio of depth to width of the loaded area is approximately the same as the ratio of the actual depth to width of the foundation. The mild steel plate (also known as bearing plate) used in the test should not be less than 25 mm in thickness and its size may vary from 300 to 750 mm. The plate could be square or circular in shape. Circular plate is adopted in case of circular footing and square plate is used in all other types of footings. The plate is machined on side and edges.
