1.1 These test methods outline procedures for testing samples of vitrified ceramic materials that are to be used as electrical insulation. Where specified limits are mentioned herein, they shall not be interpreted as specification limits for completed insulators. 1.2 These test methods are intended to apply to unglazed specimens, but they may be equally suited for testing glazed specimens. The report section shall indicate whether glazed or unglazed specimens were tested. 1.3 The test methods appear as follows: Section Test Method Related Standard(s) 6 Compressive Strength C773 13 Dielectric Strength D618 , D149 8 Elastic Properties C623 15 Electrical Resistivity D618 , D257 , D1829 7 Flexural Strength C674 , F417 9 Hardness C730 , E18 5 Porosity C373 14 Relative Permittivity and Dissipation Factor D150 , D2149 , D2520 4 Specific Gravity C20 , C329 , F77 10 Thermal Conductivity C177 , C408 12 Thermal Expansion C539 , E288 11 Thermal Shock Resistance 1.4 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use. Specific warning statements are given in 11.3 , 13.5 , and 15.3 . 1.5 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee. ====== Significance And Use ====== 3.1 For any given ceramic composition, one or more of the properties covered herein may be of more importance for a given insulating application than the other properties. Thus, it may be appropriate that selected properties be specified for testing these ceramic materials. 3.2 Pertinent statements of the significance of individual properties may be found in the sections pertaining to such properties.
