If you need to create or issue mill test certificates — as a manufacturer, distributor, or test laboratory — having the right template is the starting point. This guide covers what a compliant MTC template must include, available formats, and when a template is (and is not) the right tool.
Quick Answer
Quick Answer
A compliant MTC template must include sections for material identification (heat number, grade, dimensions), chemical composition table, mechanical properties table, heat treatment, certification statement, and authorised signature. The template format is less important than ensuring all required data fields are present and correctly filled.
Who Needs an MTC Template?
Steel mills and metals producers already have MTC templates embedded in their quality management systems. If you are a producer, your QMS-generated certificate is your template.
Distributors and service centres may need a supplementary certificate template to document processing they have performed (cutting, threading, heat treatment, coating) that adds to the original mill certificate.
Test laboratories may issue certificates on behalf of a producer where the mill's own QMS does not generate the final formatted document.
Smaller fabricators receiving inbound material may want a template to record acceptance inspection results against MTC data.
If you are a downstream buyer, you do not issue MTCs — you verify and retain them.
Required Fields in an MTC Template
Regardless of format, every MTC template must accommodate the following fields. Missing any of these will result in a non-compliant certificate that may be rejected by buyers, inspectors, or regulatory bodies.
Header Section
- Mill / manufacturer name, address, and contact details
- Certificate number (unique, sequential)
- Certificate type (EN 10204 Type 2.2 / 3.1 / 3.2 — or equivalent)
- Date of issue
- Purchase order / works order reference
- Customer name and address
Material Identification
- Heat number / cast number
- Product form (pipe, plate, bar, fitting, etc.)
- Grade designation
- Applicable standard and edition (e.g., ASTM A106-2019, EN 10025-2:2019)
- Dimensions (OD/WT for pipe; T×W×L for plate; diameter for bar)
- Quantity (number of pieces) and weight or length
- Item/tag numbers if applicable
Chemical Composition Table
A grid with:
- Column headers: element symbols (C, Si, Mn, P, S, Cr, Mo, Ni, Cu, V, Nb, Ti, Al, N, CE, etc.)
- Row 1: actual values from heat analysis
- Row 2: specification limits (max or range) for reference
- Analysis type declaration: ladle analysis / product analysis
Mechanical Properties Table
For each test performed:
- Test type (tensile, Charpy impact, hardness)
- Specimen identification or position
- Test temperature (for Charpy)
- Results columns: UTS, YS (or Rp0.2), Elongation, Reduction of Area, Impact energy (J), Hardness value
- Specification minimum/maximum for each property
Heat Treatment Section
- Treatment applied (normalised, QT, TMCP, solution annealed, as-rolled, etc.)
- Temperature range and duration if applicable
Supplementary Tests (as applicable)
- Hydrostatic test: pressure applied and result
- NDT: method, standard, acceptance criteria, result
- HIC / SSCC: test standard, specimen orientation, results
- Any other project-specific requirements
Certification Statement
- Declaration of conformance to the specified standard and order
- Reference to specific supplementary requirements met
Signatory Block
- Name of authorised inspector
- Title and department
- Signature (original or certified electronic)
- Date
- For 3.2: second block for independent inspector
Template Formats Available
Excel Template
An Excel-based template is useful for:
- Producers who generate certificates manually for small volumes
- Service centres issuing supplementary certificates
- Internal records and incoming inspection logging
A well-structured Excel template uses:
- Locked formatting cells to preserve layout
- Dropdown validation for certificate type and analysis type
- Conditional formatting to highlight values that exceed specification limits
Word / DOCX Template
A Word template works well for:
- Producing a print-ready formatted certificate
- Situations where the chemical and mechanical data is already known and needs to be entered into a formatted document
PDF Form
A fillable PDF template allows controlled form completion without risk of layout modification. Useful for:
- External distribution where formatting consistency is critical
- Digital signing workflows
QMS-Integrated Template
The most robust approach: a certificate template embedded in a quality management or ERP system that pulls data from laboratory information systems, generates the certificate automatically, and attaches a QMS-controlled document number. This eliminates manual data entry entirely.
Free MTC Template Download
A basic EN 10204-aligned MTC template in Excel format is available for download from TestCert. The template includes:
- Pre-formatted header, identification, chemistry, and mechanical sections
- Common element columns for carbon steel, low-alloy steel, and austenitic stainless
- A certification statement block
- Notes on EN 10204 3.1 signatory requirements
This template is suitable for low-volume use by service centres and test labs. For higher volumes or automated validation workflows, a dedicated platform is more appropriate.
When a Template Is Not Enough
A manual template — whether Excel, Word, or PDF — has inherent limitations:
No automatic validation. The template does not know whether the values you enter comply with the applicable specification. A human must compare each value against the standard's limits.
Format variability. If each certificate is formatted slightly differently, downstream digital processing (AI extraction, ERP integration) is harder.
No traceability linking. The template document is standalone — it is not linked to the purchase order, the delivery, or the physical material tag.
Version control. As specifications are revised, templates need updating. An outdated template may reference the wrong edition.
For organisations issuing more than a few dozen certificates per month, or for those whose certificates will be ingested into digital platforms like TestCert, a QMS-integrated or API-connected certificate generation workflow is significantly more efficient.
Frequently Asked Questions
Can I use a free MTC template for EN 10204 3.1 compliance?
A template can meet 3.1 formatting requirements, but 3.1 compliance is not just about format — it requires that an authorised inspector actually performs and certifies the testing. A template filled in by someone without that authorisation does not produce a 3.1-compliant certificate regardless of how well the template is laid out.
Should the specification limits appear on the certificate template?
It is good practice to include specification limits alongside the actual values on the MTC — this makes verification easier for the receiver. Some mills omit the limits and provide only the actual values, leaving the receiver to look up the limits independently. Including them is a courtesy and a quality assurance convenience.
What is the difference between a mill template and a supplementary certificate?
A mill MTC template is used by the producing mill to certify material properties at manufacture. A supplementary certificate is issued by a downstream processor (distributor, service centre) to document additional processing. The supplementary certificate references the original mill MTC; it does not replace it.
Do I need a specific MTC template for different specifications?
The core structure is the same across specifications, but the chemical elements required in the composition table differ. A carbon steel template (ASTM A106) needs fewer elements than an alloy steel or stainless template. It is practical to maintain grade-specific templates for your most common materials.
How do buyers process the certificates I issue?
Buyers who receive large volumes of MTCs use AI extraction tools to parse the document and extract structured data. A consistently formatted certificate with clearly labelled fields and good PDF quality significantly improves extraction accuracy. Poorly formatted or handwritten certificates increase the exception handling burden for your customers.
