1、Designation: C 1547 02Standard Classification forFusion-Cast Refractory Blocks and Shapes1This standard is issued under the fixed designation C 1547; the number immediately following the designation indicates the year oforiginal adoption or, in the case of revision, the year of last revision. A numb
2、er in parentheses indicates the year of last reapproval. Asuperscript epsilon (e) indicates an editorial change since the last revision or reapproval.1. Scope1.1 This classification covers commercial fusion-cast refrac-tory blocks and shapes. Its purpose is to set forth the varioustypes and classes
3、of these materials according to their miner-alogical compositions. These compositions are important todetermining their suitability for use in specified applications.This standard is not intended to cover commercial fused grainsor beads.1.2 This standard does not purport to address all of thesafety
4、concerns, if any, associated with its use. It is theresponsibility of the user of this standard to establish appro-priate safety and health practices and determine the applica-bility of regulatory requirements prior to use.2.
