Introduction
JJF1002-2010 "Rules for Writing National Metrology Verification Regulations", JJF1001 "General Metrology Terms and Definitions"
Together with JJF1059.1-2012 "Assessment and Expression of Measurement Uncertainty", it forms the basis to support the formulation of this regulation
Sex series norms.
This regulation is a revision of JJG 166-1993 "DC Resistors". Compared with JJG 166-1993,
In addition to editorial revisions, the changes in the relevant technical parts are mainly as follows.
---Since the DC resistance box has been independently designated as JJG 982 "DC Resistance Box", the DC high-voltage high-value resistors have been independently
Established as JJG 1072 "DC High Voltage High Value Resistors", this revision only retains the verification of DC standard resistors;
--- Added terms;
--- The dielectric strength test is deleted;
--- The cumulative difference method is deleted for the verification of the basic error;
--- Delete the variation test caused by ambient temperature;
--- Delete the variation test caused by relative humidity;
--- Deleted the variation caused by resistor self-heating.
--- The fixed period of the second-class standard resistance is set as two consecutive periods.
The previous releases of this regulation are as follows.
---JJG 166-1993;
---JJG 166-1984.
Verification Regulations for DC Standard Resistors

10Ω, 102Ω, 103Ω, 104Ω, 105Ω, a reference group composed of 8 resistance reference devices;
First-class resistance standards, including nominal values of 10-3Ω, 10-2Ω, 10-1Ω, 1Ω, 10Ω, 102Ω,
11 resistance standards of 103Ω, 104Ω, 105Ω, 106Ω, 107Ω;
Second-class resistance standards, including nominal values of 10-3Ω, 10-2Ω, 10-1Ω, 1Ω, 10Ω, 102Ω,
13 resistance standards of 103Ω, 104Ω, 105Ω, 106Ω, 107Ω, 108Ω and 109Ω;
Resistance working measuring instruments of class 0.0005 and below, including nominal values of 10-4 Ω, 10-3 Ω,
10-2Ω, 10-1Ω, 1Ω, 10Ω, 102Ω, 103Ω, 104Ω, 105Ω, 106Ω, 107Ω, 108Ω,
109Ω, 1010Ω, 1011Ω, 1012Ω, 1013Ω, 1014Ω, 19 in total.
Single-value standard resistors other than the above values can be implemented with reference to this regulation.
This regulation does not apply to.
a) Single-value or multi-value resistors and single-disc or multi-disc decade resistors used only as power ratiometers, such as Harmon gauges,
DC resistance box, voltage divider, shunt, etc.;
b) Resistors used only as permanently installed components in the circuit and resistors used only for adjustment;
c) resistors used in alternating current or pulse circuits;
d) Series or parallel resistors that are only used as accessories of electrical measuring instruments and cannot be used alone;
e) active resistors;
f) High-value resistors with a working voltage greater than 1kV.
