Foreword
This instructional document has been drafted in accordance with the rules given in GB/T 1.1-2009.
This guidance document uses the translation method identical with IEC /T S62500.2008 "Avionics Process Management Avionics
High-Speed Test Definition and Application Guide. "
This guidance document is proposed and managed by the National Avionics Process Management Standardization Technical Committee (SAC/TC427).
The guidance of technical documents drafting unit. AVIC Institute of Integrated Technology, Xi'an Aircraft Industry Institute of Computing Technology.
The main drafters of this guidance document are Li Yonghong, Sun Ruifeng, Meng Yueran, Luo Xuegang, Chang Haijuan, Zhao Wei Li and An Haijun.
Introduction
High-speed test method is proposed for the shortcomings of the traditional R & D methods. The basic idea of this new test method is
Abandoning the traditional test method based on normative compliance, pushing the newly designed product to its technical level using much higher environmental norms or incentives than the standard
Surgery capacity limit. The purpose of the High-Speed Test is to take full advantage of existing technology from the beginning of the prototype design, eliminating the potential for manufacturing
Potential defects in product failures.
In the early stages of product development, the prototype of effective high-speed test can be significantly improved in a short time the robustness of the product,
Which will prompt the product to mature as soon as possible. Through the accelerated test, you can also find the stress margin of mature products, help to accurately design environmental stress
Screening profiles. Properly enforced environmental stress, can significantly improve the efficiency of environmental stress screening.
Avionics Process Management
Avionics accelerated test definition and application guide
1 Scope
This guidance document defines the subject, rationale, scope of application and implementation procedures for high-speed tests, which are intended to facilitate product
Project managers, designers, test managers and RAMS experts to develop high-speed test program and organize the implementation of the trial.
This Guidance Document is applicable to all product projects. It is the supplier responsible for designing, developing and manufacturing products and the supplier
Contract terms to carry out high-speed test of customers to provide technical support.
Note. This guidance applies to all device types (electronics, electromechanical, mechanical, electro-hydraulic, electropneumatic, etc.) and all product layers
Times (from components, such as PCBs, mechanical components, connectors, etc., to equipment or system-level products).
2 Terms, definitions and abbreviations
2.1 Terms and definitions
The following terms and definitions apply to this document.
2.1.1
Step stress stepstressing
Gradually increase the level of stress on the product.
2.1.2
Hard fault hardfailure
Return to the low stress level will not disappear, only through the repair to eliminate the fault.
2.1.3
Soft fault softfailure
Appears at a certain level of stress and returns to a level below which stress disappears.
2.1.4
External defects extrinsicdefect
Products in the design and production process caused by defects or weak links, if the economic elimination of this type of defect will effectively enhance the production
The working margin and/or damage margin of the product.
Note. This deficiency is often caused by the failure of the design or workmanship to perform at the optimum standards, regardless of technical capability constraints.
2.1.5
Inherent defect intrinsicdefect
Defects associated with the design, material, workmanship, assembly or packaging of the product can be found under the stress conditions required by the product design code
Excited.
2.1.6
Latent defect latentdefect
Defects that actually exist in the product but have not been precipitated can not be detected using traditional performance testing methods.
2.1.7
Obvious defects in patentdefect
Product defects detectable by conventional performance testing methods after application of environmental stress. Therefore, obvious flaws are potential
Defects using certain environmental stress (such as temperature, vibration, etc.) inspired.
