Abstract
To mark the 100th anniversary of the standard time-temperature curve and fire resistance test's first usage, ASTM International held a workshop on December 6 and 7, 2018, on Advancements in Evaluating the Fire Resistance of Structures at the Washington Hilton in the United States. The conference cochairs were John Gales (York University), Marc Janssens (SWRI), Beth Weckman (University of Waterloo), and Rodney Bryant (NIST). The workshop consisted of 17 presentations on the following subjects: Examining Fire Resistance Principles; Computational Studies; and Steel, Concrete and Timber Constructions. These presentations were selected on the basis of maximum score as ranked by invited expert peer reviewers. The organizers received 57 submitted abstracts. The workshop was highlighted by an invited keynote presentation from Dr. Jim Mehaffey who presented on “Tibor Harmathy's Contribution to the Provision of the Adequate Fire Resistance of Structures”. Dr. Mehaffey spent his early career working with Dr. Tibor Harmathy. Dr. Harmathy was an active contributor to the fire resistance standards of ASTM through the decades of his career at the National Research Council of Canada. He recently passed away, and this workshop was dedicated to his legacy. Of particular importance to the workshop was the engagement with young fire engineers. Tibor's influence on generations of students was profound. His influence is still being seen on key fire resistance thesis topics such as material science, sustainability in building design, and fire dynamics. This was highlighted in the opening remarks of the workshop by the chairpersons. This ASTM workshop also featured a dinner reception with a presentation of a further seven research posters, in addition to the oral speakers. The workshop concluded with a tour of the new National Fire Lab facilities in Gaithersburg, near the conference venue. There, attendees were shown original furnace calibration documentation of Simon Ingberg's first standardized fire tests and were taken on a facility tour where demonstrations of fire severity were performed to various degrees (Figure 1). Overall, the workshop was attended by over 100 attendees, predominantly featuring next-generation student speakers, with an emphasis on global diversity. The workshop also featured historical references in printed form that provided the basis of the standard fire temperature curve's development as chosen by the workshop chairs. These featured papers are1-4 supplemental material for this editorial: the original Standard Specifications for Fire tests of Materials and Construction c19-18 (1918); Tests of the Roebling System of Fire Proof Construction (1898), which details the first organized tests performed by Ira Woolson that helped define the curve; the NBS (now NIST) study of Fire Tests of Building Columns (1916), where the standard fire curve was presented for the first time; and the Resolutions of the Associated Architects (1793), which discusses the first attempt at comparative fire testing of building materials ever recorded. As all these articles are out of copyright and were requested by attendees, they have been digitized and provided as supplemental material for universal access. Each article presented in this special issue provides both novel and useful information toward contemporary developments of fire resistance testing and fundamental theory for future advances. Due to modern developments in the construction materials industry, to ensure design safety, we are being challenged with requiring significant understanding of new materials and their performance in fire. Since 1918, the standard fire time-temperature curve has been utilized to assess the fire resistance of building materials. It remains, 100 years later, a part of the foundation of building fire codes and standards. It is actively maintained by Committee E05 of ASTM International. It is predominantly featured within the E119 standard.17 The standardized fire time-temperature curve will see continued development over the next decades. Its development depends on the involvement of those keen to participate in the standardization process.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
