Significance and Use | ||||||||
4.1 Replication is a nondestructive sampling procedure that records and preserves the topography of a metallographically prepared surface as a negative relief on a plastic film (replica). The replica permits the examination and analysis of the metallographically prepared surface on the LM or SEM. 4.2 Enhancement procedures for improving replica contrast for microscopic examination are utilized and sometimes necessary (see 8.1). 1.1 This practice covers recognized
methods for the preparation and evaluation of cellulose acetate or
plastic film replicas which have been obtained from
metallographically prepared surfaces. It is designed for the
evaluation of replicas to ensure that all significant features of a
metallographically prepared surface have been duplicated and
preserved on the replica with sufficient detail to permit both LM
and SEM examination with optimum resolution and sensitivity.
1.2 This practice may be used as a controlling document in commercial situations. 1.3 The values stated in SI units are to be regarded as the standard. Inch-pound units given in parentheses are for information only. 1.4 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. |
