Foreword
This section drafted in accordance with GB/T 1.1-2009 given rules.
This Part replaces GB/T 11297.9-1989 "pyroelectric materials dielectric loss tangent tanδ of the test method." This portion
GB 11297.9-1989 compared to the main technical changes are as follows.
--- Modify the applicable frequency range (see Chapter 1);
--- Modify the sample size requirements (see Chapter 6, 1989 edition 3.2);
--- Increased the lead measurement requirements (see Chapter 7);
--- Modify the frequency of the maximum permissible error (see Chapter 7, 1989 edition 4.2);
--- Modify the measure tanδ value of the maximum permissible error (see Chapter 7, 1989 edition 4.1);
--- 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 dielectric loss tangent tanδ [see 8.2b) ~ f)].
