Mill Test Report Automation
Extraction, PO Matching, and Compliance Register Generation

MTR (Mill Test Report) traceability software automates the extraction, validation, and reconciliation of mill certificates against purchase orders, material requisitions, and engineering specifications. For EPC and procurement teams it consolidates heat numbers, chemical composition, mechanical properties, and code references (ASTM, ASME, EN, IS) into a single audit-ready register linked back to each piece of installed material.

Manual MTR review by a procurement engineer averages 15 to 25 minutes per certificate. AI-driven processing handles the same certificate in under 30 seconds, with 99.5% field-level accuracy contractually guaranteed on safety-critical fields (heat number, grade, mechanical properties, chemistry). On a typical EPC project with 50,000 to 180,000 certificates, this is the difference between a six-month manual review backlog and a continuous handover-ready register.

Yes. Handwritten, typed, printed, digital-born, and photographed MTRs all processed natively. Regional Indian mills with handwritten certificates (JSW subsidiary mills, regional IBR-certified mills) supported alongside typed / printed certificates from major global producers (POSCO, Nippon Steel, Thyssenkrupp, ArcelorMittal). Language support: English, Japanese, Korean, Mandarin, Arabic, Russian, German, Hindi (Devanagari).

Yes. PO-to-heat-number matching is the core procurement workflow. Each extracted certificate is matched against the originating PO line item by heat number, grade, dimension, and quantity, with discrepancies flagged for procurement review. Shipment-level reconciliation across split deliveries is supported, including partial heats and substitute heats with deviation memos. Multi-heat certificates are decomposed heat-by-heat for per-heat PO matching.

ASTM, ASME (Section II, Section VIII, Section IX), EN (10204 type 3.1 and 3.2), API (5L, 6D), IS (Indian Standards), JIS, GOST, and NACE MR0175 / ISO 15156 for sour service. Code clause references are preserved through extraction so the link from any mill certificate to the applicable specification section is auditable. Non-conformances against the project material specification are flagged automatically.

TÜV SÜD, Bureau Veritas, SGS, Lloyd's Register, DNV, HSB (Hartford Steam Boiler), IRS (Indian Register of Shipping): all pre-configured. ASME authorised inspector format supported. Chief Inspector of Boilers (Indian IBR scope) format supported for every state Directorate. Custom agency formats configured at project kickoff.

IBR-scoped materials (pressure equipment per IBR 1950) are automatically tagged in the output register. Form IV register entries auto-populated with mill reference, heat number, chemistry, mechanical properties, heat treatment condition, and IBR-approved material confirmation. PESO-scoped hazardous-area equipment material traceability similarly auto-populated. One MTR extraction engagement to four regulatory registers generated concurrently (IBR, PESO, CCOE, project QA).

Mill certificate traceability is included on every paid tier. Each certificate page consumes 2 credits, so a typical mid-EPC project of 100-200 certificates fits inside Starter (1,000 credits per month) with credits to spare. Large greenfield EPC projects with 180,000+ certificates including full IBR and PESO register generation typically sit on Scale (25,000+ credits) or Enterprise with bulk data-room ingestion sized per certificate count. Indian PSU rate-card compatibility available.

Mill test certificate data extraction software automates reading mill certificates (also called Mill Test Reports or MTRs, governed by EN 10204 Type 3.1 and Type 3.2 standards) and structuring their content into queryable data for downstream procurement, QA, and regulatory workflows. The extracted fields cover heat number, material grade (ASTM A106, A312, A240, A335, A387, SA-516, SA-240, and equivalent ASME, EN, IS, JIS, GB standards), chemical composition (Carbon, Manganese, Silicon, Phosphorus, Sulphur, Chromium, Molybdenum, Nickel, Vanadium, Copper, Nitrogen, plus trace elements), mechanical properties (tensile strength, yield strength, elongation, hardness, impact energy at specified temperature), heat treatment condition (PWHT, normalising, quench-and-temper), and dimensional data. Pathnovo handles 180,000+ global mill test certificate formats including Indian (Tata Steel, JSW, SAIL, Jindal Stainless, Welspun, Maharashtra Seamless), Japanese (Nippon Steel, JFE, Kobe Steel), Korean (POSCO, Hyundai Steel), European (Tenaris, Vallourec, ArcelorMittal, Salzgitter, thyssenkrupp), American (Nucor, Steel Dynamics, US Steel), and Chinese (Baowu, HBIS, Ansteel) mill outputs. The 99.5% contractual accuracy SLA on safety-critical fields (heat number, grade, chemistry, mechanical properties) is what separates EPC-grade mill test certificate data extraction software from generic OCR.

Generic OCR reads text characters from PDFs and scanned documents. Mill test certificate data extraction software does three things generic OCR cannot. First, layout-aware field recognition: mill test certificates from 180,000+ formats have different field positions, column structures, and per-mill conventions. Pathnovo trained models recognise heat number, grade, chemistry, and mechanical-property fields regardless of where they sit on the certificate, including handwritten certificates and multi-page composite shipment documents. Second, code-driven validation: extracted chemistry is validated against ASME Section II Part A allowable ranges (e.g. SA-516 grade 70 Carbon 0.27 max for thickness ≤2 in), extracted mechanicals are validated against ASME Section II Part D allowable stress tables, NACE MR0175 sour service hardness limits are enforced where applicable. Generic OCR cannot do this validation. Third, PO line-item matching: each extracted heat number is matched against the originating purchase order line item by grade, dimension, and quantity, with discrepancies flagged for procurement review. This PO-matching layer is what makes the output usable for EPC procurement and regulatory compliance registers (IBR Form IV, PESO Form XIV, OISD 118 traceability). Generic OCR delivers a JSON blob of text; mill test certificate data extraction software delivers an audit-ready traceability register.

Eight criteria distinguish EPC-grade mill test certificate data extraction software from metals-industry or generic-OCR alternatives. (1) Format coverage: at least 180,000+ formats including Indian, Japanese, Korean, European, American, and Chinese mill outputs in EN 10204 Type 3.1 and 3.2 conventions. (2) Handwritten and photographed certificate support, common in Indian regional mills and emergency procurement. (3) Multi-script and multi-language native processing (English, Mandarin, Korean, Japanese, Arabic, Russian, German, Hindi). (4) Code-driven chemistry and mechanical validation against ASME Section II Part A and Part D, plus NACE MR0175 for sour service. (5) PO line-item matching by heat number, grade, dimension, and quantity, with multi-heat and split-shipment handling. (6) Indian regulatory output (IBR Form IV, PESO Form XIV / XV, CCOE licence register) auto-populated from extracted MTR data, the four-register output most EPC contractors need but cannot easily build with generic tools. (7) Inspector-ready gap report formatted for TÜV SÜD, Bureau Veritas, SGS, Lloyd's Register, IRS, HSB, and Chief Inspector of Boilers, surfacing missing certificates, MTR-PO mismatches, chemistry deviations, hardness gaps for sour service, missing HIC test data, missing impact test data, missing third-party inspection sign-off, heat treatment record gaps, and IBR sign-off gaps. (8) Contractual 99.5% field-level accuracy SLA with remedy clause, not a marketing benchmark. Pathnovo meets all eight criteria; metals-industry tools and generic OCR typically cover one to three of them. See the MTR traceability software comparison for the side-by-side.
