Introduction
The test system table is based on JJF1104-2003 "National Metrological Verification System Table preparation rules" as the basis for
JJG 2053-2006. Compared with JJG 2053-2006, in addition to editorial changes, the test system
The main changes are as follows.
- sent to the International Bureau of Metrology (BIPM) according to the national kilogram of the original kiln and the national kilogram
The results of the calibration, modified the measurement uncertainty of the two reference weights.
--- modified the original balance of the technical indicators. As in.2005, China Institute of Metrology introduced a vacuum
Learning quality comparison instrument and supporting the air density measurement system, the laboratory has updated the original instrument balance, so the original balance
Of the technical indicators and ancillary equipment has changed.
--- modified the quality of the sub-benchmark group of technical indicators, such as material density, measurement results of the uncertainty, the original
Of the kilograms of sub-benchmark weight range extended to 1kg ~ 1g of the national quality of the sub-benchmark group weight.
--- Change the "conversion quality" to "agreed quality".
--- increase the "quality comparison instrument" the use of the scope and value of traceability approach.
--- check the system block diagram in accordance with the previous text to do the appropriate changes.

Quality measurement equipment test system table
1 Scope
This test system table applies to the mass transfer of the quality measuring instrument.
The verification system table specifies the national mass measurement basis for the mass unit "kg", the quality measurement standard and the work meter
The use of measuring instruments; the full set of basic devices, metrological parameters included in the accuracy level measuring instruments;
Home quality benchmarks by means of the quality of the sub-reference group and the standard measuring instruments to the work of measuring instruments to pass the quality unit of the value of the process
Order, given its uncertainty or maximum allowable error and basic transfer method.
In the actual use of the test system, the quality of the standard weight and the weight of the work can be used according to the nominal value
Need to be in the corresponding accuracy level up, down to expand.
All quality values used in accordance with the law must be within the specified accuracy range, with a certain proportion can be determined strictly
And 1kg quality reference weight (also known as. national kilogram of the original device) corresponds to the quality value. All the quality of the use of law
The value must be in accordance with the test system table to 1kg quality benchmark weight trace; in carrying out the calibration, can also be used as the amount
Value based on the source.
2 quality measurement benchmark
The quality measurement basis includes 1kg quality reference, 1kg ~ 1g quality sub-reference group.
2.1 1 kg quality benchmark
2.1.1 1kg quality reference weight for reproduction and preservation according to the international kilogram of the original instrument obtained by the quality of single
Position, and with 1kg ~ 1g quality sub-reference group and the standard measuring instruments to the work of measuring instruments to pass the amount of unit weight
Value to ensure the unity of domestic quality measurement.
2.1.2 1kg quality reference weight and its ancillary equipment
2.1.2.1 China's highest quality of the quality of the weight and ancillary equipment include. 1kg quality benchmark weight,
1kg quality testify the benchmark weight (also known as the national kilogram of the original instrument), the corresponding quality comparison instrument, air density measurement
Quantity system.
2.1.2.2 1kg quality reference weight, number 60, is the diameter and height are 39mm platinum iridium alloy straight cylinder,
Of which. platinum accounted for 90%, iridium accounted for 10%. The weight of the weight of the nominal value of 1kg, the vacuum quality value from the international meter
The volume (BIPM) gives the uncertainty of the measurement results expressed as the synthetic standard uncertainty (k = 1)
BIPM's latest certificate).
2.1.2.3 1kg quality testify the reference weight, number 64, is the diameter and height are 39mm platinum iridium alloy straight round
Column, of which. platinum accounted for 90%, iridium accounted for 10%. The weight of the weight of the nominal value of 1kg, the vacuum in the quality of the value
BIPM gives the uncertainty of the measurement results to the synthetic standard uncertainty (k = 1) (expressed as BIPM's latest
Certificate).
2.1.2.4 quality comparison device, weighing 1kg, the actual scale value of 0.1μg, a single measurement of the standard deviation is not
At 0.6 μg.
2.1.2.5 Air density measurement system
