3 Terms and definitions

The following terms and definitions apply to this document. 3.1 Product maturity productmaturity A measure of product maturity that is used to measure product design, quality, technical completeness, and applicability to meet product expectations. The extent of the goal. 3.2 Technical specification limit technicalspecificationlimit The stress limit value expected by the product specified by the product technical specification, the product is functioning normally within the stress limit value, and the performance parameter Meet the requirements. 3.3 Design limit designlimit The stress limit values that a given product is designed to meet. 3.4 Design margin designmargin In order to meet the requirements of technical specifications during the design process, the discreteness of the product is considered in consideration of various factors, so that the stress tolerance range of the product is suitable. When the amount is higher than the technical specifications. Expressed as the difference between the design limits and the limits of the specification. 3.5 Working limit operatinglimit When the working characteristics of the test sample no longer meet the requirements of the technical conditions, but the test stress strength is reduced, the test sample can still return to normal. The value of the test stress intensity tolerated when operating characteristics. 3.6 Job margin operatingmargin The difference between the working limit of the product and the design limit.
