GB/T 18791-2002 in English

《GB/T 18791-2002电子和电气陶瓷性能试验方法》由339-1（工业和信息化部（电子））归口，主管部门为工业和信息化部（电子）。
本标准规定了电子和电气陶瓷材料的体积密度、显气孔率、透液性、抗压强度、抗折强度、杨氏弹性模量、泊松比、导热系数、抗热震性、平均线膨胀系数、绝缘强度、介电常数和损耗角正切值、体积电阻率等性能的测试方法。本标准适用于电子和电气陶瓷材料通用性能的测试。

Scope

This standard specifies the bulk density, apparent porosity, liquid permeability, compressive strength, flexural strength, Young's modulus of elasticity, Poisson's ratio, thermal conductivity, thermal shock resistance, and average linear expansion of electronic and electrical ceramic materials. Coefficient, dielectric strength, dielectric constant and loss tangent, volume resistivity and other performance testing methods. This standard applies to the testing of the general performance of electronic and electrical ceramic materials.
