The technical indicators and test methods of this specification mainly refer to OIMLR59.2006(E) "Moisture Measurement of Grain and Oilseeds" Calibration Instrument", OIMLR76-1.2006 (E) "Non-automatic Weighing Instrument Part 1.Measurement and Technical Requirements Test", OIMLR76-2.2007 (E) "Non-automatic Weighing Instruments Part 2.Test Report" and GB/T 23111-2008 "Non-automatic Weighing Instruments Contents related to moisture, measurement performance, anti-interference performance, test procedures and record format in "Automatic Weighing Apparatus" are included in this manual. The specification is a revision of JJF 1367-2012 "Outline for Type Evaluation of Drying Moisture Meter". Compared with JJF 1367-2012, except for editorial modifications, the main technical changes of this specification are as follows. --- The relevant application classification code is given in "Scope" (see 1); ---Change "water loss rate" to "water loss rate", and add the term "water loss rate determination method", and add Add 1d/60s to determine the rate of dehydration; (see 3.7 and 3.8); --- Change "weighing device" to "weighing device"; --- Added key components and material table content (see 4.1 and 4.2); ---Deleted the regulations on the original license mark and serial number of manufacturing measuring instruments in the legal system of measurement (see 5.3.1); --- Modifications have been made to the submitted test prototype (see 5.6); --- Adjusted part e of the verification division value (see Table 2 and 6.4); --- Modify the definition of moisture measurement error (see 6.6); --- Added requirements for horizontal indicating devices (see 7.3.3); --- Deleted the requirements for electrical safety test items; ---Deleted the requirements for packaging and transportation, transportation and storage adaptability test items; --- Specific requirements for test equipment are given (see 9.4); --- Increased the sodium chloride solution standard substance, and the mass fraction of the original ratio of sodium chloride solution and sodium chloride solution The mass fraction control requirements of standard substances are uniformly U=0.03% (k=2) (see 9.4.1.2); --- Modified the calculation formula of the moisture measurement error of the analog indicating moisture analyzer (see 9.7.4); --- Change the method of "judgment of type evaluation results" to all evaluation items that are qualified to be judged as qualified (see 10); ---Modified the content of "Preparation of Sodium Chloride Solution" (see Appendix B). The release status of previous versions of this specification is as follows. ---JJF 1367-2012.
