GMW › Complete Document History General Specification for Electrical/ Electronic Components and Subsystems, Electromagnetic Compatibility Global. GMW, GMW and GMW (All three documents of specifications that apply to GMW EMC test The GMW EMC Test Plan (Appendix B). These requirements have “gone global” in the form of GM Worldwide (GMW) EMC .. GMW – Validation Acceptance Process (EMC Control Plan).

These inputs shall be supplied either within the load simulator, by support equipment provided by the supplier, or by the EMC test lab. If this motor is in a corrosive environment, such as washer fluid, exposed to salt, etc. Table 2 of GMW shall be used to aid in the determination of applicable component and subsystem tests.
Battery and Switched Battery e. Modifications, alterations, internal part swaps, hardware and software changes are not considered carryover and must be validated according to the requirements. Construction materials and building This is due to the increased radiated emissions due to expanded bus? If multiple part numbers, identify which vehicles part numbers are used. This could include, for instance, vacuums or non-atmospheric pressure conditions for pressure sensors, fuel-substitutes for fuel mix detectors, etc.
The analog properties of the bus electrical signal e. In some cases, it may make sense to select a specific sample for test that represents the entire DUT family. The Component EMC Test Plan also provides a mechanism for ongoing enhancements and improvements to the test methodology that improves vehicle level test correlation.
If using device with an 8 MHz clock or higher, use at least 4 layers. Use SMD components with very short traces to the return plane. Input filter time constant should be at least 1 ms, especially for analog inputs. This may require special software to decrease the data rate to be within the bandwidth limitations of analog fiber optic transmitters.
Coupling capacitors and the test injection point at the DUT. The analog circuits and the digital circuits should be in separate zones. Duplicate entries for input names may exist under different modes. Connector pin assignment is important when working with twisted harnessing.
Log In Sign Up. Do not use the simplified block diagrams as found in any of the reference standards. Provide further description below as necessary: Mechanical systems and components for general use If signals are to be monitored via oscilloscopes, meters, etc. List all individual lines or pins pulled up to battery, switched battery e.
Tables A7, A8 and A9 should be used to provide this information. Refer to Figure A1 in 31033 A. This may be included in a header or footer. Pulse 1 is applicable even to battery lines due to assembly plant sequencing — no damage allowed. Be sure to locate the terminals adjacent to each other in the same connector. Gmq section assumes that production software is not mandatory; the use of specialized software is acceptable. Design Analysis and Performance. The complete series consists of the following documents: An electrical circuit diagram is preferred.
The term carryover means that the product qualified for a prior program and is exactly the same product being used for the future program. For development reports, a watermark that does not obstruct data is preferred. Mining and minerals Test results obtained from testing prior to test plan approval shall not be published in a validation report.
The largest dimension [m] of any discontinuity should be less than? GMW Locate the pins of connectors or devices if possible to make room for filling in the area between the 33103 with copper. The complete series consists of the following documents: Combination of digital and analog that requires bus messaging to a defined load.
User Interface These typically include display panels, gauges, feature 3130 buttons, backlighting LEDs, etc. For this situation, the motor case shall be connected to the motor winding via a small ceramic capacitor 1 nF, typical. Seam contact vmw should be placed according to? Petroleum and related technologies If not specified in other specifications, use the following tolerance for voltage and current: Company organization, management and quality. Include mode information for each entry.
Specify other special test arrangements that apply to this test.

Field Effect Transistor FET devices may be capable of surviving these transients; however, bipolar devices will require extra protection e.
