Foreword
This revised standard adopts ISO 17562.2001 "Fine ceramics (advanced ceramics, advanced technical ceramics) --- linear thermal expansion of monolithic ceramics department
Number of test methods for mandrel Law "(in English).
This standard adopts ISO 17562.2001, the made the following technical corrections.
a) expanding the use of the standard range, allowing "other inorganic non-metallic materials can also refer to use";
b) a reference to the standard ISO 3611 and ISO 6906 changed to refer to GB/T 1216 and GB/T 21389;
c) To delete references to standards ISO 7991 and IEC 60584-1;
d) 10.2 Calibration of the instrument to "comply with GB/T 1216 requirements micrometer";
e) Added Appendix A of the linear thermal expansion coefficient of alumina reference data and corresponding references.
This standard also made the following editorial changes.
a) with a decimal point '. 'Instead of a comma as the decimal point,' ';
b) Remove the preface international standards;
d) 5.6 to delete the note at the original duplicate;
e) Modify the format of Table 1, making it easier to understand.
This standard replaces GB/T 16535-1996 "ceramic works linear thermal expansion coefficient test methods."
This standard and GB/T 16535-1996 compared to the main changes are as follows.
a) the heading "Engineering Ceramics" to "fine ceramics";
b) Temperature range increases to "near liquid nitrogen temperature to a maximum temperature range of 1500 ℃" (see 1);
c) increasing the normative references (see 2);
d) increase the "Terms and definitions" (see 3);
e) the expected increase in the value of the uncertainty (see 8);
f) increase the instrument calibration (see 10);
g) Increase Appendix A, Appendix B and Appendix C.
The Standard Appendix A and Appendix B is a normative appendix Appendix C are informative appendices.

Fine Ceramics linear thermal expansion coefficient Test Method
Jack method
1 Scope
This standard specifies the test in the range of 1500 ℃ fine ceramic wire and the thermal expansion coefficient of linear thermal expansion coefficient from near liquid nitrogen temperature to a maximum temperature
Principle of test methods, equipment, samples, test procedures and results of calculations.
This standard applies to bulk fine ceramics, other inorganic non-metallic materials may also be reference.
2 Normative references
The following documents contain provisions which, through reference in this standard and become the standard terms. For dated references, subsequent
Amendments (not including errata content) or revisions do not apply to this standard. However, according to research encourages the parties to the agreement
Study whether the latest versions of these documents. For undated reference documents, the latest versions apply to this standard.
GB/T 1216 outside micrometer

3 Terms and Definitions
The following terms and definitions apply to this standard.
3.1
At a temperature between T1 and T2 is linear coefficient of thermal expansion ΔL/L0.
Where. ΔL = (L2-L1), L0 is the length of the sample at room temperature.
Note. Suppose when the temperature changed from T1 to T2, the length of the sample changed from L1 to L2.
3.2
Jade α
Average heat at a temperature between T1 and T2 expansion coefficient α of jade ΔL/(L0 × ΔT), where. ΔT = (T2-T1).
3.3
Instantaneous linear thermal expansion coefficient α is close to T2 average linear thermal expansion coefficient of the time T1,
That is. α = lim
T2 → T1
Jade [] α.
Principle 4
Under certain atmosphere, a small load is applied to the sample of known dimensions, certain ramp rate of heating or cooling the sample to set
Given temperature, measuring the change in length of the specimen, record temperature changes, the sample is calculated linear thermal expansion coefficient and transient linear thermal expansion specific temperature
coefficient.
