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 and health practices and determine the applicability of regulatory limitations prior to use. Specific precaution statements are given in 11.3, 13.5, and 15.3.


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.
