Standard Practice for Pressing and Drying Refractory Plastic and Ramming Mix Specimens

SIGNIFICANCE AND USE
3.1 This practice is useful for producing uniform specimens of refractory plastics and ramming mixes for use in standard ASTM tests. Samples thus formed may be used for referee testing when setting specifications between producer and user. Establish by mutual agreement and specify in the report the forming parameters such as sample size, workability, and forming pressure when referee testing.  
3.2 This practice is applicable for preparing test specimens of various sizes. Note that 9 by 41/2 by 21/2 in. (228 by 114 by 64-mm) samples, because of their large cross-section, have a greater tendency to form flaws during pressing, handling, and drying than smaller cross-sectional samples.  
3.3 The purpose of this practice is to minimize flaws in pressed specimens. It is not intended to duplicate all field installation conditions.  
3.4 Variations in workability as determined by Test Method C181 can significantly affect the number of flaws contained in a specimen. Establish by mutual agreement the workability level when comparing tests between two laboratories.  
3.5 This practice is not intended for preparing specimens of basic ramming mixes, anhydrous tap-hole mixes, nor resin bonded mixes.
SCOPE
1.1 This practice covers the pressing and drying of chemically and non-chemically bonded alumin-silicate and high alumina plastic and ramming mix refractory specimens classified in accordance with Classification C673.  
1.2 The values stated in inch-pound units are to be regarded as the standard. The values given in parentheses are for information only.  
1.3 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.
