It is the responsibility of the user d5443 this standard to establish appropriate safety and health practices aatm determine the applicability of regulatory limitations prior to use.

However, when it has been determined by trial that this is not possible, prepare the rock specimen to the closest tolerances practicable and consider this to be the best effort Note 1 and report it as such and if allowable or necessary for the intended test, capping the ends of the specimen as discussed in this practice is permitted. In addition, they are representative of the significant digits that generally should be retained. Most commonly, this situation presents itself with weaker, more porous, and poorly cemented rock types and rock types containing significant or weak or both structural atsm.

Best effort in surface preparation refers to the use of a well-maintained surface grinder, lathe or lapping machine by an experienced operator in which a reasonable number of attempts has been made to meet the tolerances required in this procedure. Specimen grinding machine The machine is used to grind and polish rock and concrete specimens, natural stones, ceramic materials, etc. However, the use of balances or scales recording pounds of mass lbm shall not be regarded as nonconformance with this standard.

Rock specimen grinding machine Used to grind and polish rock and concrete specimens, natural stones, ceramic materials, etc. However, some of the information contained with in this practice and in standard Test Method C may v4543 be of use to preparing other test specimen shapes.

Note, when mass measurements are added to determine densities or unit weights, add the following. Work Item s – proposed revisions of this standard.
