Carbon equivalent
carbon_equivalent
IIW-style carbon equivalent from certificate chemistry
Scores if within ±0.3% of the reference value.
Calculates source-bound steel certificate compliance metrics from a deterministic SSC-15 task-owned source pack. The template combines one mill certificate, material schedule, welding criterion, fire note, structural excerpt, and material compliance memo.
with-tool: The model is given an executable Python calculator script.
One template produces many comparable benchmark tasks while keeping the scoring contract fixed.

Each template is sampled at three tiers. Harder tiers may hide inputs, forcing the model to infer them from the scenario description.
For this template, difficulty scales through parameter and scenario ranges rather than hidden information.
The exact instruction and parameter contract used to generate this task, pinned to the published library source.

1You are a structural material reviewer checking a task-owned synthetic SSC-15 steel certificate package.2 3Use only the task-owned synthetic source pack values shown below for numeric grading. Product compliance directories and certificate workflows shape the context only; they are not extra data sources for this instance.4 5## Scene6 7- Product: `SSC-15-LH-01`8- Mill certificate: `CERT-15-STEEL-01`9- Material schedule: `MAT-15-SCHED-01`10- Welding criterion: `WELD-15-CRIT-01`11- Fire design note: `FIRE-15-NOTE-01`12- Structural calculation excerpt: `CALC-15-STRUCT-01`13- Material compliance memo: `MEMO-15-STEEL-01`14 15All checks use the same steel certificate and material schedule. Do not change the product identity, certificate identity, material grade, fire basis, or memo status unless you explicitly flag a source conflict.16 17## Source Values18 19| Item | Value |20|------|-------|21| Carbon | {{ carbon_percent }} percent |22| Manganese | {{ manganese_percent }} percent |23| Chromium | {{ chromium_percent }} percent |24| Molybdenum | {{ molybdenum_percent }} percent |25| Vanadium | {{ vanadium_percent }} percent |26| Nickel | {{ nickel_percent }} percent |27| Copper | {{ copper_percent }} percent |28| Carbon-equivalent limit | {{ carbon_equivalent_limit }} |29| Certificate capacity | {{ certificate_capacity_kn }} kN |30| Design load | {{ design_load_kn }} kN |31| Fire load ratio | {{ fire_load_ratio }} |32| Required fire temperature | {{ required_fire_temperature_c }} degC |33| Matching certificate fields | {{ matching_certificate_fields }} |34| Required certificate fields | {{ required_certificate_fields }} |35| Completed memo sections | {{ completed_memo_sections }} |36| Required memo sections | {{ required_memo_sections }} |37 38Carbon equivalent equals `C + Mn/6 + (Cr + Mo + V)/5 + (Ni + Cu)/15`.

Include a source-boundary statement that this is a task-owned synthetic source pack. Do not claim authority approval, accepted project evidence, software export validity, full standards compliance, executable real source-pack parsing, generated benchmark readiness, or benchmark readiness.43 44Include a fenced JSON block with exactly these numeric keys:45 46```json47{48 "carbon_equivalent": <numeric_value>,49 "carbon_equivalent_margin": <numeric_value>,50 "structural_capacity_margin_kn": <numeric_value>,51 "structural_utilization": <numeric_value>,52 "critical_steel_temperature_c": <numeric_value>,53 "fire_temperature_margin_c": <numeric_value>,54 "certificate_field_match_fraction": <numeric_value>,55 "material_memo_completeness_fraction": <numeric_value>,56 "overall_pass_score": <numeric_value>57}58```59 Each generated task is drawn from one of these realistic scenario bands.
Site contexts ground each scenario in a real locale the model can use to infer hidden values.
