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).

Only the latest approved standards are applicable unless otherwise specified. An electrical circuit diagram is preferred. Provisions for overvoltage, load dump event and reverse ymw protection should be located on battery 12 V input.
This document is one out of a series of three global EMC standards documents that specify EMC test and validation requirements. Those figures are generic, by nature, and cannot show the details required by a DUT-specific Test Plan.
Identify specification and revision number being used.
If using device with an 8 MHz clock or higher, use at least 4 layers. Aircraft and space vehicle engineering Connector pin assignment is important when working with twisted harnessing. Provide graphical picture showing discharge locations. These inputs shall be supplied either within the load simulator, by support equipment provided by the supplier, or by the EMC test lab. Provisions for all 4 corners are acceptable, then determining best configuration during testing.
All non-electrical outputs to be gw, including lamps, gauges, etc. Do not use the simplified block diagrams as found in any of the reference standards. C2, power input filter should provide 20 dB of attenuation at kHz using bulk storage electrolytic C[? More detailed appendices for design review and test plan.
Nothing in this standard supercedes applicable laws and regulations.
Shipbuilding and marine structures Any deviation from the approved test plan and any applicable standards, including, but not limited to, test setup and test procedure. Avoid using expanded memory microprocessors if possible. Provide further description below as necessary: If it is found necessary to current starve a tri-state buffer, for example see Figure B1, also Figure B631003 is recommended that each of the inputs referenced to VCC also have provisions for gmq same current starving device.
The default orientations for this test are: Petroleum and related technologies Minimum number of test samples is two. List all individual pins, case discharge locations, discharge type, simulator voltages, discharge network type and a description of the pin signal.
Route clock traces between power and ground planes if possible. Materials handling equipment If a section is not applicable, this shall be stated in the document after the relevant section description. A unique identification number must be assigned to the sample along with a description of the DUT and harness, including Hardware and Software Version.
List all product part numbers that this test plan is applicable to. This includes directly accessible faceplates, displays, and remote buttons and test connectors.
Mechanical systems and components for general use There should be at least one bulk storage capacitor on the PCB. Shipping Delivery Order tracking Returns. Direct to Local Chassis? Traces are required to be symmetrical to each other or balanced with little trace length.
Design analysis and performance is a part of the design review.

Company organization, management and quality. B2 Printed Circuit Board B2. Also, provide justification for any omissions in testing for any of the DUT test modes listed. Pulse 1 is applicable even to battery lines due to assembly plant sequencing — no damage allowed.
