Physico-chemical test terms for forensic science trace evidence

1 Scope

This standard specifies the general terms and definitions of trace physical evidence and its testing methods in forensic science.

This standard applies to the unified theory of terminology and basic concepts in the field of physical and chemical examination of trace physical evidence in forensic science and other related fields.

Solution, other areas can also be used for reference.
