The problem: A tender document asks for "test certificates for durability, airtightness, fire rating and safety." The manufacturer replies with a CE declaration, a photo of a test rig, and a "1,000,000 cycles" claim with no report behind it. Which documents actually constitute evidence — and which are marketing?

What counts as test evidence

Credible evidence has four elements: (1) a named standard and edition, (2) a report or certificate from an accredited laboratory (ISO/IEC 17025), (3) a specimen description that matches the product being supplied (size, configuration, hardware), and (4) traceability — report number, date, lab accreditation number. A Declaration of Performance or certificate of conformity summarizes results but is not a substitute for the underlying test report when the claim is challenged.

Test categories for steel medical and cleanroom doors

Dimensional accuracy. Verify leaf and frame dimensions, diagonal squareness, flatness of the leaf, and installed clearances against drawing tolerances. Dimensional checks are cheap and catch the majority of field disputes — an out-of-square frame defeats every downstream performance feature (sealing, latching, fire clearances).

Durability / cycling. Cyclic test standards (e.g., EN 1191/EN 12400 in Europe; ANSI/BHMA grade cycles in the US for hardware) open and close the door repeatedly. Typical claims range from 200,000 to 1,000,000+ cycles. Ask what was cycled: the complete door set with its actual hinges, closers, and seals — or a bare leaf on ideal hinges. A 1M-cycle claim on hardware alone does not validate the assembly.

Operating safety (automatic doors). Evidence of conformity with ANSI/BHMA A156.10 (full power) or A156.19 (low energy) — or EN 16005 in Europe — covering entrapment protection, sensor zones, forces, and time delays. For powered operators on fire doors, an NRTL listing is required.

Air leakage. ASTM E283/E283M measures leakage under specified pressure differentials in a lab rig; results are stated as cfm/ft² (or m³/h·m²) at a stated pressure. For smoke doors, UL 1784 sets acceptance caps; for isolation rooms and cleanrooms, the project specification sets the target. Beware claims of "hermetic" or "airtight" with no leakage figure at a stated pressure — the words have no standardized meaning.

Fire resistance. Test reports to UL 10C, NFPA 252, or EN 1634-1 state the rating in minutes for the tested assembly — leaf, frame, glazing, and hardware together. Substituting a different hinge, lock, or larger vision panel can void the rating unless covered by the certification scope or an engineering assessment.

Radiation shielding (X-ray doors). Lead equivalence (e.g., 1.5 mm Pb) must be verified at a stated kVp per recognized methods (e.g., NCRP/IEC-based shielding calculations). The shielding must be continuous — including the frame, astragals, and threshold — and typically verified on site with a radiation survey after installation.

Electrical safety. Powered operators require evidence against applicable electrical standards (e.g., UL 325 for door operators in North America, EN 60335 series in the EU), plus EMC testing for environments with sensitive medical equipment.

Common mistakes

  • Accepting a test report for a different door size or configuration than quoted.
  • Treating a factory internal test ("in-house lab") as equivalent to accredited third-party testing. In-house data is useful for QA but weak in disputes.
  • Claims without a standard: "tested to 50 Pa" is meaningless without the method (E283? EN 1026?) and the result.
  • Ignoring report expiry or superseded standard editions.

Practical checklist

  • [ ] For each claimed performance: standard + edition + accredited report number.
  • [ ] Specimen description matches the quoted configuration (sizes, glazing, hardware).
  • [ ] Fire: UL 10C/NFPA 252/EN 1634-1 report covers the full assembly.
  • [ ] Air leakage: result stated at a defined pressure, by ASTM E283 or equivalent.
  • [ ] Automatic doors: A156.10/A156.19 (or EN 16005) conformity + NRTL listing where required.
  • [ ] Radiation doors: lead equivalence at stated kVp, continuity details, post-install survey plan.
  • [ ] Keep records traceable to project submittals for the life of the installation.
