A data file with two or more may be used, such as multiple fuel Machine communication using a submersible pumping oil tank. b) leakage detection systems shall be given by the quantitative or qualitative output results. Qualitative output should reference to Table 1, the results are displayed through Or failure. 9.3.2.3 Minimum number of samples of each type of system should be selected subject data file is as follows. a) the output of the quantitative results of the system. greater than or equal to 100 files (the same number of samples in a tank selected not more than 15); b) the results of qualitative output system. greater than or equal to 240 files (the same number of samples in a tank selected not more than 36). 9.3.2.4 The selected data files recorded in an ambient temperature range of the first 20, 40 and 80 points as the division point, the database files 9.3.4.2 Thus, the volume of oil stored value vi i-th record by vi 'in place, see the calculation formula (3) as follows. v'i = vi-Σ j = 1 (Tj-tj-1) rj (3) 9.3.4.3 Analog losses previously accumulated, and also subtracted from the amount of stored oil volume. This time should also bleed every time unloading Leakage losses accumulate, so the subtracted value monotonically. 9.3.4.4 When connecting pipe between the tank through the siphon, the amount of leakage within a certain time interval should be divided by the number of suction tank siphon connection, and then This value is subtracted from the record in a single tank. 9.3.5 Analog pipeline leaks (self-priming pumps and submersible pumps) 9.3.5.1 This leakage simulation mode is assumed when the oil tanker work at a constant rate of leakage from the fuel line. Each data processing When a file is first calculated the total time pumping oil through the pipeline. Calculated at a constant leakage rate is R, the duration of time period T The total volume of liquid loss, divided by the total time of pumping oil, resulting in leakage rate R during hair oil ', see formula (4). R '= R × T j = 1 (Tej-tsj) (4) Where. tej --- j-th fuel termination time; tsj --- start time j-th refueling; The total number of files n --- refueling; T --- documents starting and ending time used. 9.3.5.2 record representing a value stored oil volume of the reservoir by subtracting the amount of the loss recorded during the interval when two leakage rate R 'cause, but Only tanker during this period when the hair oil work apply. The time period prior to simulate the loss of all accumulates, and from the oil deposit Volume (including during tanker not in operation) minus. Seepage losses should also be accumulated each time the unloading, which subtracted Monotonically increasing value. 9.3.5.3 Thus, the volume of the i-th record by the value vi vi 'instead of, the calculation shown in Equation (5) below. v'i = vi-Σ j = 1 (Tej-tsj) R '(5) Where. m --- refueling times. 9.3.5.4 When the tank through the communication line through the provisions of leakage within the time interval should be divided by the number of penetrating tanks, then this value from even Tank record then subtracted. 9.3.6 Analog leakage rate --- dosing system 45 file 9.3.6.1 The selected sample is further divided into four groups, including a group of 15 files, the other three groups each of 10 paper Member. In Table 1 the leakage rate based on the rate of leakage, calculated for each of the following segments into analog data file after the leak. a) 15 files. Analog leakage rate is zero; b) 10 files. Analog leakage rate based leakage rate multiplied by 0.5; c) 10 documents. analog leak rate equal to the base rate of leakage; d) 10 files. Analog leakage rate based leakage rate multiplied by 1.5. 9.3.6.2 9.3.6.1 When the press of a) ~ d) a leak simulation, the actual leakage rate each document should be within 20% of the simulated rate of ± Randomly selected in order to prevent the subject system will calculate the leakage rate rounding. 9.3.6.3 9.3.6.1 When the press of a) ~ d) a leak simulation, you should use the same set of original documents constant leakage and leakage two variables mold Intended to facilitate the subsequent contrast level gauge distinguish between different types of leakage performance. 9.4 Analysis of test results and reports 9.4.1 Analog leak test results 9.4.1.1 should be based on test 9.3.8 Test 1 to 3 and 7 to test 9 test results, according to the statistical analysis method given in 9.5 Review estimate. Test test 4 to 6 (variable leakage rate) With just mean difference test. All trials should be adopted that requirement The detection accuracy rate and false alarm rate and between the requirements to be simulated leak indication. If a test does not meet the relevant 9.1.1a) ~ 9.1.1c) in Any one of the standard, the system can not obtain type designations. In addition, if the leakage rate constants and variables simulated mean difference less than 0, System can not give the type designations. Therefore, if the test is passed, it should meet the following conditions, see equation (6). rv-rc > 0 (6) Where. The average variable indicating rv --- simulate leakage leakage rate; The average leakage simulation indicates rc --- constant leakage rate. 9.4.1.2 Qualitative variable leakage rate of the system pass/fail results should be at least the same number of times with a constant rate of leakage. NOTE. Due to leakage of liquid as predetermined positive and negative reservoir increases, to test by subtracting the rate of the variable rate constant should be greater than zero. 9.4.2 Eligibility 9.3.2 complete file filtering based on the response 9.1.3,9.1.4 and test conditions 9.1.5 required for confirmation. Only experimental results If these conditions are met in order to give the type quality certification. Under all conditions, regardless of whether there is leakage simulation, tank leak test results 9.5.12 variance should meet the requirements, the conditions of use can not be otherwise obtained type approval. But when the full results of a simulated leak test Foot performance requirements, and these data are not in use within the conditions, it should also be given in the form of quality certification. 9.5 Statistical Analysis 9.5.1 Overview Estimated leakage rate and pass or fail indication for each simulated leak test record, the subject can be used to estimate the accuracy of the system and False alarm rate performance is up to standard. This section respectively on both quantitative and qualitative methods of data analysis methods are described. 9.5.2 Quantitative basic statistical system Take n indication and analog leak rate data to ......Tips & Frequently Asked Questions:Question 1: How long will the true-PDF of GB/T 30040.5-2013_English be delivered?Answer: Upon your order, we will start to translate GB/T 30040.5-2013_English as soon as possible, and keep you informed of the progress.
