    Withdrawn Rationale:

    This guide covers procedures that should be used by forensic document examiners (Guide E4441) for examinations and comparisons involving typewritten items and related procedures.

    Formerly under the jurisdiction of Committee E30 on Forensic Sciences, this guide was withdrawn in January 2017 in accordance with section 10.6.3 of the Regulations Governing ASTM Technical Committees, which requires that standards shall be updated by the end of the eighth year since the last approval date.

    1. Scope

    1.1 This guide covers procedures that should be used by forensic document examiners (Guide E 444) for examinations and comparisons involving typewritten items and related procedures.

    1.2 These procedures are applicable whether the examination and comparison is of questioned and known items or of exclusively questioned items.

    1.3 These procedures include evaluation of the sufficiency of the material (questioned, or known, or both) available for examination.

    1.4 Procedures are also given for taking exemplars from typewriters and the proper handling of typewriters or parts of typewriters that might be relevant.

    1.5 These methods can also be applicable (in whole or in part) to examinations of documents prepared on other impact and nonimpact printing devices.

    1.6 The particular methods employed in a given case will depend upon the nature of the material available for examination.

    1.7 This guide might not cover all aspects of unusual or uncommon examinations of typewritten items.

    1.8 This guide cannot replace training (Guide E 2388) or experience and should be used in conjunction with professional judgment.

    1.9 The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard.

    1.10 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.
