ASTM C1190 Standard Practice for Location of Test Specimens from Magnesia-Carbon and Impregnated Burned Basic Brick
ASTM C1190 碳酸镁和焙烧浸渍碱性砖试样配置标准规范
 
This practice defines a procedure that ensures reasonably consistent preparation of specimens for product testing and evaluation.
This practice can be used in the laboratories of producers, users, and general interest parties for research and development or quality control work. It is particularly useful for interlaboratory comparisons on products, for repetitive evaluations or comparisons of products or product quality, and in specifying a uniform preparation practice for specimens for acceptance testing.
If pitch impregnated samples are prepared by wet cutting or drilling, care should be taken in drying them. If the samples are heated to facilitate drying, the temperature to which they are heated should not be so high that it causes drainage of pitch from the samples.
Porosities of metal-containing brick must be measured using kerosene or mineral spirits because using water will result in an artificially low result.

1. Scope
1.1 This practice covers a procedure for preparing test specimens from magnesia-carbon and impregnated burned basic brick. This practice generally concerns preparation of test specimens from brick greater than 13 in. (33 cm) in length. These brick are mainly manufactured for use in electric arc furnaces and basic oxygen furnaces.
1.2 The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard.
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.
