ASTM D6097 固体介电绝缘材料中有通气孔的水柱提升的相关抗性的标准试验方法
日期:2012-02-08 09:51
Other voltages, frequencies, temperatures, aqueous solutions, and defects can be used to evaluate specific materials for specific applications. Temperatures should not exceed the softening or melting point of the material or 10 to 15C below the boiling point of the salt solution. Any nonstandard conditions should be reported along with the results.
Tree-growth rates generally increase with the test frequency. An acceleration factor due to frequency is given by (f/60)k where f is the test freque
