    en.wikipedia.org/wiki/Worst-case_circuit_analysis

    The circuit's EVA and RSS results are determined for beginning-of-life and end-of-life states. These results are used to calculate part stresses and are applied to other analysis. In order for the WCCA to be useful throughout the product’s life cycle, it is extremely important that the analysis be documented in a clear and concise format.

  3. Rainflow-counting algorithm - Wikipedia

    en.wikipedia.org/wiki/Rainflow-counting_algorithm

    Regions where the water will not flow identify the rainflow cycles which are seen as an interruption to the main cycle. Reduce the time history to a sequence of (tensile) peaks and (compressive) valleys. Imagine that the time history is a template for a rigid sheet (pagoda roof). Turn the sheet clockwise 90° (earliest time to the top).

  4. Temperature cycling - Wikipedia

    en.wikipedia.org/wiki/Temperature_cycling

    Temperature cycling (or temperature cycle) is the process of cycling through two temperature extremes, typically at relatively high rates of change. It is an environmental stress test used in evaluating product reliability as well as in manufacturing to catch early-term, latent defects by inducing failure through thermal fatigue .

    The regulation took into account various national cycles such as World-wide Heavy-Duty Certification procedure (WHDC) and World-wide Motorcycle Test Cycle (WMTC). [7] It also took into consideration the 1958 Agreement and the 1998 Agreement, those of Japan and the United States Environmental Protection Agency (US EPA) Standard Part 1066.

    IEC 60068 is an international standard for the environmental testing of electrotechnical products that is published by the International Electrotechnical Commission (IEC).. IEC 60068 is a collection of methods [1] for environmental testing of electronic equipment and products to assess their ability to perform under environmental conditions including extreme cold and dry heat.

  7. Driving cycle - Wikipedia

    en.wikipedia.org/wiki/Driving_cycle

    The "Drive-cycle" basically is the representative of the road. Drive cycles are used to reduce the expense of on road tests, time of test and fatigue of the test engineer. The whole idea is to bring the road to the test lab (a chassis dynamo-meter) or to the computer simulation. Two kinds of drive cycle can be made.

  8. World Motorcycle Test Cycle - Wikipedia

    en.wikipedia.org/wiki/World_Motorcycle_Test_Cycle

    The World Motorcycle Test Cycle (WMTC) is a system of driving cycles used to measure fuel consumption and emissions in motorcycles. The methods are stipulated as part of the Global Technical Regulation established under the United Nations ’ World Forum for Harmonisation of Vehicle Regulations , also known as WP.29.
