Introduction
This syllabus is modified using OIMLR107.2007 (E) non-continuous cumulative automatic weighing instrument (accumulated hopper scale)
[DiscontinuousTotalizingAutomaticWeighingInstruments(TotalizingHopperWeigh-
Ers)], combined with the actual situation of China's non-continuous cumulative automatic weighing instrument (accumulated hopper scale). In writing format
The requirements of JJF 1016-2014 "Guidelines for the preparation of type evaluation outlines for measuring instruments" were implemented.
Compared with OIMLR107-1.2007 (E), the main changes in this syllabus are as follows.
--- Write the difference in format.
The second chapter of the R107 measurement requirements, Chapter 3 technical requirements, Chapter 4 electronic weighing requirements, Chapter 5 measurement
Control and Chapter 6 test methods are revised to be the fifth chapter of the legal management requirements, Chapter 6, measurement requirements,
Chapter 7 General Technical Requirements and Chapter 9 Test Conditions and Methods, the abbreviations and symbols are changed to Appendix B;
---The content is different.
The contents of the Chapter 8 Type Evaluation Project List and the Chapter 10 Type Evaluation Results are added.
The previous versions of JJG648-1996 were released as follows.
---JJG648-1990.
Non-continuous cumulative automatic weighing instrument (accumulated hopper scale)
Type evaluation outline
1 Scope
This syllabus specifies the test requirements and tests for the discontinuous cumulative automatic weighing instrument (hereinafter referred to as “accumulated hopper scale”).
Test procedures.
This outline is applicable to the type evaluation work of the national authorized type evaluation laboratory, other technical institutions or manufacturing enterprises.
The corresponding test can be carried out with reference to this syllabus.
This syllabus applies to the type evaluation of cumulative hopper scales with a classification code of 12061500.
This outline does not apply to the following types of cumulative hopper scales.
--- Accumulated hopper scale of "dynamic weighing";
--- Accumulated hopper scale with cumulative bulk load obtained by multiplying multiple weighing cycles by the mass of the preset constant load.
