Publication Information

Symposium authors are required to submit their papers for ASTM publication in Selected Technical Papers (STP), an online and printed, peer-reviewed publication for the international scientific and engineering community. STP papers should be full-length technical papers of approximately 10,000 words, significantly contribute to the technical literature, and must include a review of past work in the relevant area and present information of current interest or probe new fields. After the final selection of abstracts has been approved, the ASTM Editorial Office will send authors’ instructions via email, but also can be found by clicking here.

Manuscripts to be peer reviewed for the STP are due online no later than DATE at the ASTM Editorial Office. The corresponding author (the author who is the main contact with ASTM Headquarters) will receive a copy of his/her paper in portable document format (PDF). All published authors will have the opportunity to purchase reprints of their papers at a nominal cost. Only those papers submitted by the manuscript due date will be included in the STP. Please note that all submitted papers are subject to peer review by two independent reviewers.

The STP will be submitted to the Library of Congress with an ISBN number and will be reviewed for inclusion in the Web of Science Conference Proceedings Citation Index (CPCI) and Google Scholar.
