The use of this test method will assist manufacturers, users, and regulatingauthorities to refer to uniform test methods to determine if the
9、devices are accurate.5. Apparatus5.1 Reference materials may include, but are not limited to, test blocks to verify linear measurements for ultrasound and linearprobes, “phantom carcasses” to verify non-linear measurements used in devices that use magnetic energy absorption, photographicplates for v

13、M standard and is intended only to provide the user of an ASTM standard an indication of what changes have been made to the previous version. Becauseit may not be technically possible to adequately depict all changes accurately, ASTM recommends that users consult prior editions as appropriate. In al
14、l cases only the current versionof the standard as published by ASTM is to be considered the official document.Copyright ASTM International, 100 Barr Harbor Drive, PO Box C700, West Conshohocken, PA 19428-2959. United States15.2 Manufacturers provide reference materials to use in the initial setup a
15、nd calibration of evaluating devices before use; thesereference materials can be used as standards for ensuring accuracy after they are verified and documented by an independent thirdparty. Reference material shall be uniquely identified (for example, serial number) and retained for additional testi
16、ng andcalibration to ensure the accuracy of the device as it is being used over time.5.3 Verification of the reference material requires: (1) that the reference materials stated measurements are accurate (thisrequires that the error of the labeled measurements can not be greater than one-third of th
17、e smallest allowable error acceptablewhen the reference material is used to verify an evaluating device), and (2) the reference material is an appropriate proxy for thecharacteristic being evaluated by the device or system (the reference material is considered appropriate if it is has been designedt
18、o be used as a reference material, and it is constructed to retain its characteristics for a reasonable period of time under conditionsof normal use).6. Calibration and Standardization6.1 Reference MaterialThe user is responsible for ensuring that all reference materials used to test its evaluating
19、device havebeen verified as accurate by an independent third party. The frequency of this verification shall be every two years or less.6.1.1 When an evaluation device or system is being calibrated at initial setup or adjusted after it has been found to be out oftolerance, the user shall ensure that
20、 the device is adjusted as close as practicable to the indications of the reference material.7. ProcedureProcedures7.1 The production daily test for evaluating devices require a minimum of three readings from each third of the normal operatingrange of the device.7.2 Autofom Test Procedures:7.2.1 Tra
21、nsducer Test:7.2.1.1 Dry the transducer array so that no water is left.7.2.1.2 Test function is activated on the control panel.7.2.1.3 Wait 1 min to check that none of the transducers are starting automatically.7.2.1.4 Put some gel on the test block (reference material).7.2.1.5 The transducer is che
22、cked with the test block.7.2.1.6 Remove gel from transducer.7.2.1.7 Repeat 7.2.1.4 7.2.1.6 on all 16 transducers. Take ten measurements with the test block for each required measurementon each transducer.7.2.2 After each transducer test, the results will be recorded. At the end of a test series, the
23、 latest result from each transducerwill be written on the last line. If a transducer is approved more than nine times, an “X” will indicate ten or more approved tests.7.2.3 A complete test of the transducers requires that the test block be correctly placed on each transducer. It is important thatthe
24、 test block rest on the whole surface on the transducer head with light pressure. When starting the test, all transducers must be“0”. If this is not the case, the transducer might be broken (wait approximately 1 min after activation of the test function). If atransducer is defective, then the displa
25、y will show no results.7.2.4 Verify that all measurement errors are within NIST Handbook 44 or this test method, as applicable.7.3 Fat-o-Meater Test Procedures:7.3.1 Push the morning control button.7.3.2 Take ten measurements with the test block (reference material) for each required measurement (se
