ASTM E3521-26

1.1 This practice is for use by forensic science service provider (FSSP) personnel responsible for designing a training program for forensic science practitioners (FSPs) who will perform glass analyses and comparisons.

1.2 This practice outlines the tasks, goals, and objectives that allows the trainee to acquire discipline specific skills and knowledge necessary to be qualified in forensic glass analysis.

1.3 This training program is intended to supplement the minimum training requirements as set forth in Practice E2917.

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, health, and environmental practices and determine the applicability of regulatory limitations prior to use.

1.5 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.

3.1 This training practice identifies the necessary information and guidelines to create a training program that prepares a trainee to become qualified in forensic glass analysis. The trainee is directly supervised by an expert deemed qualified by the FSSP as a trainer or supervisor of glass analysis.

3.1.1 Upon successful completion of the program and demonstration of competency, the trainee becomes qualified to independently perform examinations, interpret analytical results, write reports, and testify in court.

3.2 This training practice provides an overview of standard test methods and techniques used in forensic glass analysis.

3.2.1 This training practice could include some techniques and instrumentation that are beyond the capabilities of the FSSP.

3.2.2 Each FSSP is expected to customize their training program specific to their procedures, instrumental techniques, and capabilities, to include specialized or newer technologies not covered in this practice.

3.3 Additional glass analysis training beyond that which is listed here is beneficial to the trainee. Such supplemental training could include off-site courses, tours of manufacturing plants, and specialized training by experienced practitioners or subject matter experts.

3.4 Continuing education and training is recommended. Additional training provides a forensic glass practitioner with the opportunity to remain current in the field. Continuing education requirements are addressed by FSSPs, standard developing organizations, accreditation bodies, or licensing bodies (for example, Practice E2917).

3.5 Section 6 of this practice provides the foundation for a comprehensive training program in the forensic examination of glass. It is expected that an FSSP will modify portions of the program to appropriately correspond to the available instrumentation and services offered by that FSSP.

3.6 Section 6 is in a modular format for adaptation suited to an individual FSSP’s training program. The order in which the individual modules are taught is determined by the FSSP. Recommendations as to lessons, practical exercises, progress monitoring, and trainee evaluations are included.
