--- Refine the test procedure;

--- Amend the Appendices A and B, the contents of which included in the body of the standard. The standard proposed by China Shipbuilding Industry Corporation. This standard by the National Standardization Technical Committee Marine boat marine materials application technology at the Technical Committee. This standard was drafted. China Shipbuilding Industry Corporation seventh fifteen Institute. The main drafters of this standard. Yusuo Long, cover school week, Wei Wei, Wang Yue group. This standard replaces the standards previously issued as follows:

1 Scope

GB/T 16304-2008 is the Chinese national standard on test methods of the properties for piezoelectric ceramics - test for relation between electric field and strain, in the field of electronics. The /T suffix marks it as a recommended standard: it is not compulsory by itself, but it becomes binding as soon as a contract, a tender or a customer specification calls it up - which in practice is how most foreign buyers meet it. It was issued on 4 August 2008 by the General Administration of Quality Supervision, Inspection and Quarantine of the People's Republic of China; Standardization Administration of China, and has been in force since 1 February 2009. Classification: ICS 31-030, CCS L90. This page is published from the official record of the standard held by the Chinese standards administration: the identification, the dates, the classification and the issuing body are taken from there. The clause text, the tables and the numeric limits are in the document itself, which is delivered complete in English translation.

This standard specifies the piezoelectric ceramic material under external electric field characteristics of static and dynamic strain test conditions, principle of the method, the test procedure And test results and other statements. This standard applies to testing piezoelectric ceramics field strain characteristics.

3 Terms and Definitions

GB/T 3389.1 and established the following terms and definitions apply to this standard.

3.1 Static strain quantumofstaticstrain In the DC field excitation, a direction to produce the original size of the deformation and the direction of the ratio of the piezoelectric ceramic material.

3.2 Static strain characteristics propertiesofstaticstrain Static variables with DC excitation should change the relationship between field strength.

3.3 Dynamic strain quantumofdynamicstrain The maximum amplitude of the alternating electric field in the piezoelectric ceramic material incentives, resulting in a certain direction (resonance frequency) and the direction of the original size ratio.

3.4 Dynamic strain characteristics propertiesofdynamicstrain Dynamic strain relations with ac excitation change the electric field intensity.
