Introduction

This regulation refers to the international recommendation OIMLR61-12004 (E) "Gravity Automatic Loading Weighing Instrument" (Automatic GravimetricFilingInstruments), combined with the actual situation of my country's gravity automatic loading weighing instrument verification, Revise JJG 564-2002 "Gravity Automatic Weighing Instrument (Quantitative Automatic Weighing Instrument)". according to Compile the rules of JJF1002-2010 "National Metrological Verification Regulations Compilation Rules". Compared with JJG 564-2002, in addition to editorial changes, the main technical changes of this regulation are as follows. ---The name of the procedure was changed to "Gravity Automatic Loading Weighing Apparatus", which is in line with the international recommendation OIMLR61-1 2004 (E) consistent; ---Clarified that this regulation is only applicable to the initial verification, subsequent verification and in-use verification of gravity-type automatic loading weighing instruments Check, it is not applicable to the type evaluation of gravity automatic loading weighing instrument (see 1); --- Only some of the terms applicable to verification are selected (see 3.1); ---Modified the range of the maximum allowable deviation (MPD) for each loading (see 5.2); ---Modified the relationship between the number of loading times and the preset value (see 7.4); ---Added the static weighing verification of the integrated verification method [see 7.5c)]; ---Deleted the requirements of type evaluation and the form of type evaluation; ---The contents of the first verification, subsequent verification and in-use inspection have been refined, and the list of verification items has been added (see 7.7); ---Added Appendix A Verification Record Format, Appendix B Verification Certificate Inner Page Format and Appendix C Verification Results The format of the inside pages of the knowledge book (see Appendix A, Appendix B and Appendix C). The release of previous versions of this regulation. ---JJG 564-2002; ---JJG 564-1988. Verification Regulations for Gravity Automatic Loading Weighing Instruments

1 Scope

This regulation is applicable to the first verification, subsequent verification and in-use inspection of gravity automatic loading weighing instruments.

2 Reference documents

The following documents are cited in this regulation. JJF1181 Weighing instrument measurement terms and definitions For dated reference documents, only the dated version applies to this regulation; for undated references The latest version (including all amendments) is applicable to this regulation.

3 Terms and units of measurement

3.1 Term The terminology used in this regulation is consistent with JJF1181, and part of the terminology is quoted for ease of use and understanding. Language, and added special terms only applicable to this regulation. 3.1.1 Gravity automatic weighing instrument automaticgravimetricfiling instruments The bulk material is divided into a predetermined and actually constant quality charge, and the charge is loaded into the automatic container Weighing apparatus. 3.1.2 Weighingunit In an automatic weighing instrument, a device that provides weighing information of the load being weighed. 3.1.3 Loading fil A combination of one or more loads that constitute a predetermined mass. 3.1.4 Feed control device feedcontroldevice A device that adjusts the feeding rate in the feeding device. 3.1.5 Loading setting device filsettingdevice A device that allows setting the preset value of the loading. 3.1.6 Final feedcut-off device finalfeedcut-offdevice A device that controls the cut-off of the final feed and makes the average value of the feed meet the preset value. The device can contain Adjustment and correction function of materials. 3.1.7 Correction device correctiondevice A device for automatically correcting the settings of a gravity-type automatic loading scale. 3.1.8 Reference particle mass of the material referenceparticlemassofaproduct The mass of the reference particle is equal to the average value of the ten largest basic particles selected from one or more charges. 3.1.9 preset value In order to specify the nominal value of the charge, it is preset by the operator with the aid of the charge setting device, expressed in mass units Value.
