Engineering validation test
An engineering verification test is performed on first engineering prototypes, to ensure that the basic unit performs to design goals and specifications. Verification ensures that designs meets requirements and specification while validation ensures that created entity meets the user needs and objectives.
Tests
Tests may include:- Functional test
- Power measurement
- Signal quality test
- Conformance test
- Electromagnetic interference pre-scan
- Thermal and four-corner test
- Basic parametric measurements, specification verification
Importance
Identifying design problems and solving them as early in the design cycle as possible is a key to keeping projects on time and within budget. Too often, product design and performance problems are not detected until late in the product development cycle, when the product is ready to be shipped.Prototyping
In the prototyping stage, engineers create actual working samples of the product they plan to produce. Engineering verification testing is used on prototypes to verify that the design meets pre-determined specifications and design goals. This valuable information is used to validate the design as is, or identify areas that need to be modified.Design Verification Test
Design Verification Test is an intensive testing program which is performed to deliver objective, comprehensive testing verifying all product specifications, interface standards, Original Equipment Manufacturer (OEM) requirements, and diagnostic commands. It consists of the following areas of testing:- Functional testing
- Performance testing
- Climatic testing
- Reliability testing
- Environmental testing
- Mechanical testing
- Mean Time Between Failure (MTBF) prediction
- Conformance testing
- Electromagnetic compatibility testing and certification
- Safety certification
