Foreword

This standard replaces GB/T 15750-1995 "of piezoelectric ceramics aging testing procedures." This standard compared with GB/T 15750-1995, there are the following changes.

--- Modify the test conditions;

--- Increasing the aging time performance of tests;

--- Aging tests to determine the temperature of the treatment temperature. The standard proposed by China State Shipbuilding Corporation. This standard by the National Standardization Technical Committee Marine boat marine materials application technology at the Technical Committee. This standard was drafted. the state-owned China Shipbuilding Industry Corporation seventh twenty-one plant. The main drafters of this standard. Zhu Bin, Zhang Hui, Zhang Liying. This standard replaces the standards previously issued as follows:

--- GB/T 15750-1995. Properties of piezoelectric ceramics test methods Aging test

1 Scope

GB/T 15750-2008 is the Chinese national standard on test methods for the properties of piezoelectric ceramics - test for the ageing properties, 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 20 October 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 April 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 aging time and temperature aging test conditions, test methods and test procedures and calculation method. This standard applies to the piezoelectric ceramic material aging time and temperature aging test.
