1、Designation: E 1732 96a (Reapproved 2005)Standard TerminologyRelating to Forensic Science1This standard is issued under the fixed designation E 1732; the number immediately following the designation indicates the year oforiginal adoption or, in the case of revision, the year of last revision. A numb

2、er in parentheses indicates the year of last reapproval. Asuperscript epsilon (e) indicates an editorial change since the last revision or reapproval.1. Scope1.1 This is a compilation of terms and correspondingdefinitions used in the forensic sciences. Legal or scientificterms that are generally und

3、erstood or defined adequately inother readily available sources may not be included.1.2 A definition is a single sentence with additional infor-mation included in notes. It is reviewed every five years, andthe year of last review or revision is appended.1.3 Definitions identical to those published b
