This standard replaces the standards previously issued as follows. --- GB/T 21223-2007.IntroductionTest procedures for aging properties estimation procedure is described in detail; a particular environmental stress (such as temperature, radiation, and partial discharge) under aging General document also covers the test procedure in this section of the book. In many cases, a particular performance as a function of time for different aging under stress to be measured, and find selected at each arrival aging stress Standard end expiration time. This failure time and aging stress diagram can be used to obtain exposure to similar stress predetermined sample failure Estimates of time, or to obtain a predetermined value will cause the failure stress estimated time. Physical and chemical laws of aging could always control the introduction of such an assumption, such as stress at a fixed age, is the assessment of Between aging time and energy, or a certain mathematical properties of functions (such as square root or logarithmic) and there is a linear relationship between the aging time. Similarly, in Failure between stress and aging time, or there may be a linear relationship between mathematical function of these variables. This section describes a suitable method for the linear relationship. Solid columns illustrate the method by thermal aging, which may be simple chemical process Is assumed to be degraded obey Arrhenius law, it is simply the number of dead time is a linear function of the inverse of the thermodynamic temperature. This section provides procedures to calculate under normal inspection data. We shall not test data normality, because the test is available to small Sample set of data is not credible. However, this method of distribution under normality has been the case over the long-term results and not all inspection data use. Aging test statistical analysis Guide Part 1. the establishment of normal distribution of test results The method based on the average1 ScopeGB/T 21223 provisions of this part of the statistical methods used to analyze and evaluate the results of aging data. This section includes based on mean values \u200b\u200bof normally distributed test results on numerical methods. These methods only in compliance with the test data Specific assumptions mathematics and the laws of physics when effective. This section also provides some statistical tests on the validity of certain assumptions method. This section applies to the complete data set and censored data set. This section provides a subset of data processing based on the concept of the program data. References [1] indicates the push for calculation Statistical validity of the export parameter data set of coefficients. 2 terms, definitions and symbols 2.1 Terms and Definitions The following terms and definitions apply to this document. 2.1.1 Ordered data ordereddata According to a set of data in order, from the appropriate direction, the column data in each equal to or greater than the previous one. Note. in this section, "Ascending" indicates that the data to the first data is the smallest in this way arrangement. 2.1.2 Order statistics order-statistic Each individual value in an ordered set of data called order statistics, with its numerical position in the sequence is represented. 2.1.3 Incomplete data incompletedata Values \u200b\u200babove and (or) below a specified point is unknown ordered data. 2.1.4 Censored data censoreddata The number of unknown value is known incomplete data. Note. If the above start at a predetermined value or below censored, belong to the class Ⅰ censored; if Censored starts at a predetermined amount above or below the order statistics It belongs to the class Ⅱ Censored. This section relates only to Class Ⅱ Censored. 2.1.5 Truncated data truncateddata The number of unknown value is unknown incomplete data. Note. This section does not involve the truncated data. 2.1.6 Saw coefficient Sawcoefficient Coefficients to calculate a list of groups of primary statistical functions required by the invention JGSaw. Note. in this section there are four factors. Saw coefficient was originally defined as the fifth, for estimating the variance of [7]. ......Tips & Frequently Asked Questions:Question 1: How long will the true-PDF of GB/T 21223.1-2015_English be delivered?Answer: Upon your order, we will start to translate GB/T 21223.1-2015_English as soon as possible, and keep you informed of the progress.
