Designation:C1190–95 (Reapproved 2005)
Standard Practice for
Location of Test Specimens from Magnesia-Carbon and
Impregnated Burned Basic Brick
This standard is issued under the fixed designation C1190; the number immediately following the designation indicates the year of
original adoption or, in the case of revision, the year of last revision. A number in parentheses indicates the year of last reapproval. A
superscript epsilon (´) indicates an editorial change since the last revision or reapproval.
