Foreword
This section drafted in accordance with GB/T 1.1-2009 given rules.
This Part replaces GB/T 11297.11-1989 "Test methods of pyroelectric material dielectric constant." This portion of the GB/T 11297.11-1989
Compared to the main technical changes are as follows.
--- Modify the applicable frequency range (see Chapter 1);
--- Modify the test atmospheric conditions (see 51, 1989 Version 3.1.1 ~ 3.1.3.);
--- Modify the sample size (see Chapter 6, 1989 Version 3.2.1);
--- Modify the sample requirements (see Chapter 6, 1989 Version 3.2.2);
--- Modify the capacitance measurement accuracy (see Chapter 7, 1989 edition 4.3);
--- Modify the sample processing (see 81, 1989 Version 5.1.);
--- Added "first sample cartridge into the thermostat, then the sample holder access sample box" and by open and short correction instrument
Accurate, direct measurement of the sample capacitance [see 8.2d) ~ f)].

4 measuring principle
For infinite and between the electrode plates with the medium without gaps parallel plate capacitor dielectric, capacitance (C) according to formula (1).
C = εε0
(1)
Where.
C --- capacitance in farads (F);
permittivity ε --- perpendicular to the direction of the plate, is no unit quantities;
ε0 --- vacuum permittivity, ε0 \u200b\u200b= 8.854 × 10-14F/cm;
A --- electrode area, in units of square cm (cm2 for);
d --- plate spacing that the thickness of the sample medium in centimeters (cm).
If pyroelectric material such capacitors, the dielectric constant according to equation (2).
ε =
ε0A
C (2)
Using a precision LCR meter measured capacitance (C), according to formula (2) to calculate the pyroelectric material permittivity (ε).
In measuring the capacitance (C), the sample holder and sensing lead capacitance exists a constant (the C0), with the capacitance (C) in a parallel state. therefore
Measured capacitance (Cce) according to equation (3) Calculated.
Cce = C C0 (3)
Substituted into the formula (2), the dielectric constant of the final expression (3) capacitance (C) of formula (4).
ε =
ε0A
Cce (-C0) (4)
Permittivity any pyroelectric materials are anisotropic, and according to the principle of a parallel plate capacitor dielectric constant should be measured perpendicular
