Foreword
This standard is drafted in accordance with the rules given in GB/T 1.1-2009.
This standard uses the re-drafting method to amend the use of international legal system of measurement organization 61 international recommendations OIMLR61 "gravity automatic loading balance
Quot; Automatic Gravimetric FilingInstruments.2004 (E) (R61-1, R61-2).
R61 International Recommendations were prepared by the OIMLTC9/SC2 Automatic Weighing Subcommittee in.2004. R61 "gravity automatic
"Weighing Weighing" is divided into two parts. Part 1 (R61-1) "Measurement Requirements and Technical Requirements Test"; Part 2 (R61-2) "Type Evaluation
report".
In order to be consistent with the R61 international proposal, the R61 International Recommendations Appendix A and Appendix B are the normative
Appendix A and Appendix B.
As China's current measurement of product management model and the international are not the same, so this standard and R61 international recommendations there is a small amount of
Differences, for the sake of comparison, a list of the terms of this Standard and the International Recommendations are listed in the Appendix C of the Information.
Due to the legal requirements of our country and the special needs of industry, this standard has been modified when international recommendations are adopted. These technical differences are used
The vertical single line identifies the margins in the terms of the articles they are involved in. A list of technical differences and their causes is given in Appendix D,
for reference.
This standard addresses the preamble of the R61 International Recommendation.
This standard is proposed by the Federation of Light Industry.
This standard is nationalized by the National Standardization Technical Committee (SAC/TC97).
This standard is responsible for drafting units. Saimo Electric Co., Ltd.
This standard participates in the drafting unit. Shanghai Dahe Weighing Apparatus Co., Ltd., METTLER TOLEDO (Changzhou) Weighing Equipment System Co., Ltd., Wuxi

Gravity automatic weighing instrument
1 Scope
This standard specifies the terms, product type, requirements, inspection methods and rules for gravity automatic weighing instruments, marking, packaging, shipping and
Storage.
This standard also evaluates the metrological characteristics or technical characteristics of gravity automatic weighing instruments in a traceable way, providing them with standardized
Summarize test procedures and forms.
This standard applies to gravity automatic weighing instruments that automatically achieve a predetermined mass by loading single or multiple loads. Gravity type
Automatic weighing instruments in this standard referred to as weighing instruments.
This standard does not limit the maximum weighing or minimum weighing of the weighing instrument. In addition, you can also ask the weighing instrument to meet other national standards
Specified certain requirements. For example, when the weighing instrument in the normal use of non-automatic mode, should meet the non-automatic weighing the relevant standards
For the charge is less than or equal to 25kg of the situation, should meet the pre-packaged commodity content of the relevant standards.
