Why Some Suppliers Refuse to Share Full Aluminum Composite Panel Fire Test Reports

Why Some Suppliers Refuse to Share Full Aluminum Composite Panel Fire Test Reports

You request a fire test report. The supplier hesitates. They offer a one-page certificate instead. They claim the full report is "confidential" or "proprietary." They assure you the product is compliant—just trust them.

But why would a legitimate supplier refuse to share documentation that proves their product is safe?

       The answer is rarely innocent. In the wake of global cladding tragedies—Grenfell Tower (72 lives), Lacrosse Building (23 floors in 11 minutes)—building product transparency has become a legal and ethical imperative. Suppliers who refuse to provide complete, verifiable fire test reports are often hiding something: failed test results, missing accreditation, mismatched product identity, or liability exposure.

This guide exposes the common reasons suppliers withhold full fire test reports, the red flags procurement professionals must recognize, and the strategies to demand—and verify—complete documentation before any panel is installed.

1. The Fundamental Distinction: Certificate vs. Full Test Report

Before understanding why suppliers refuse to share reports, procurement professionals must understand what they should be requesting.

 A genuine fire test report is not a single page. It includes photographs of the tested sample, detailed descriptions of the test setup, raw measurement data, and the signature of the laboratory director. As one building product supplier explains, the NCC/BCA explicitly requires "a complete copy of the original certificate, report, or document... [including] photos, diagrams, or a detailed description in the full report".

A certificate without this supporting documentation is not evidence of compliance. It is a marketing document.

2. The Hidden Reasons Suppliers Withhold Full Reports

Reason 1: The Tests Were Never Conducted (Fabricated Documentation)

The most alarming reason a supplier cannot provide a full test report is simple: the tests never happened. The certificate is fabricated. There is no underlying data to share.

The global scale of this problem is significant. A Senate inquiry into non-conforming building products in Australia identified "reports of fraudulent certification" as a major issue contributing to the cladding crisis. The inquiry noted that product certification fraud—including fake test reports—has enabled non-compliant, combustible panels to enter the market undetected.

As the Grenfell Inquiry revealed, some manufacturers engaged in "deeply entrenched dishonesty," including manipulating test data and obscuring the true composition of their products.

Procurement implication: If a supplier cannot produce a full report with a verifiable report number from an accredited laboratory, assume the certificate is fraudulent. Reject immediately and report to regulatory authorities.

Reason 2: The Report Does Not Apply to the Product Being Sold (Certificate Borrowing)

A supplier may possess a genuine fire test report for a different product. A test was conducted on a panel with an A2 mineral core and 0.50mm skins. A test was conducted in a specific wall assembly configuration. But the panels they are selling you have PE core and 0.30mm skins. The test report does not apply.

This practice, known as "certificate borrowing," is widespread. The UK government's post-Grenfell testing program revealed that 111 high-rise buildings had cladding systems that failed large-scale fire tests—despite holding certificates claiming compliance.

The BRE (Building Research Establishment) tests confirmed that a cladding system using ACM panels with polyethylene filler "does not meet current building regulation guidance". Yet these panels had certificates. The certificates were valid for component-level tests—not for the complete wall assembly.

Procurement implication:** Verify that the product described in the full test report (core type, thickness, alloy, coating) exactly matches the product being delivered. Any discrepancy—even minor—invalidates the report.

Reason 3: The Testing Laboratory Was Not Accredited (No Formal Recognition)

A supplier may provide a full report from a laboratory without recognized accreditation. The report may look official, complete with logos and data. But without accreditation from bodies like NATA (Australia), UKAS (United Kingdom), CNAS (China), or NABL (India), the report carries no formal weight.

As one building product manufacturer states, they "will only use fire tests and fire assessments from NATA or IANZ accredited laboratories, as our view is that only these fire engineers are appropriately qualified persons". These accredited laboratories operate under ISO/IEC 17025, are peer-reviewed, and maintain access to industry-wide testing knowledge.

Non-accredited laboratories may use incomplete methodologies, make inappropriate assumptions, or lack the quality controls necessary for reliable results.

Procurement implication: Before accepting any test report, verify the laboratory's accreditation status through the accrediting body's online directory (e.g., NATA, UKAS CertCheck, CNAS database).

Reason 4: The Report Reveals Assembly-Specific Limitations

A fire test report does not just state a classification. It describes the exact assembly that was tested: the specific panel, insulation type, attachment method, and air gap.

A supplier may withhold the full report because it reveals limitations that would disqualify the product for your project. For example, a report might show that the panel achieved A2-s1,d0 only when installed with non-combustible mineral wool insulation—but your project uses combustible insulation.

The distinction between material, product, and system testing is critical. As one fire engineering firm explains: "An aluminium composite panel may: require combustibility testing of the core insulation material; undergo additional testing of the assembled panel; and be installed in a wall system that needs a fire resistance test".

Procurement implication: Request the full report and verify that the tested assembly matches your intended installation. If the supplier refuses to disclose assembly details, assume the product will not perform as required for your configuration.

Reason 5: The Report Exposes Legal Liability Exposure

Perhaps the most strategic reason suppliers withhold full reports is liability. The Lacrosse case in Australia established that fire engineers, architects, and builders can be held proportionally liable for specifying or approving non-compliant products.

The fire engineer on the Lacrosse project was found to have breached their duty by failing to "inquire into and assess the range of construction materials for the purpose of establishing potential fire hazards". The Tribunal found that the engineer's report was "too generic and superficial" and failed to discover "the use of 100% polyethylene core ACP".

When a supplier withholds a full report, they may be attempting to prevent a paper trail that could establish liability. If you cannot verify the product's compliance through documented evidence, you cannot be held responsible for approving it—or so the supplier might hope.

The reality: The Lacrosse decision establishes the opposite. Building professionals have an affirmative duty to inquire into and verify product compliance. Accepting incomplete documentation is itself a failure of due diligence.

Reason 6: The Report Is Outdated or Uses Superseded Standards

A fire test may have been legitimate—20 years ago. But building codes evolve. Test standards are updated. A panel tested to a superseded version of EN 13501-1 or ASTM E84 may not meet current code requirements.

The Address Hotel fire in Dubai (New Year's Eve 2015) highlighted this danger. The cladding system had passed ASTM E119 (fire resistance) but had never been tested to NFPA 285 (fire propagation). The engineer who supervised the 2007 test stated that the test "tells us nothing about the flammability of the system" because "it was the gypsum board" that provided the fire resistance, not the cladding panels.

Procurement implication: Verify that the test standard cited in the report is the current version. For US high-rise applications, demand NFPA 285—not just ASTM E84.

Reason 7: The Report Contains Proprietary Information (Legitimate Concern)

Some suppliers legitimately withhold certain sections of test reports to protect proprietary information. This may include specific chemical formulations of fire-retardant additives or unique manufacturing processes.

However, legitimate suppliers will never withhold the core compliance information: laboratory accreditation, report number, product identification, classification, and assembly details. The NABL-accredited in-house testing facility at Aludecor demonstrates that legitimate manufacturers can be transparent while protecting intellectual property.

Procurement implication: Accept redaction of proprietary chemical formulas. Do not accept redaction of product identification, test results, or assembly descriptions.

3. Red Flags Checklist: When to Reject Documentation

        4. What to Demand from Suppliers (The Documentation Standard)

Mandatory Documentation for ACP Procurement

Sample Request Language

Include this in your purchase order:

"Supplier shall provide a complete fire test report from a NATA/UKAS/CNAS/NABL-accredited laboratory. The report must include: laboratory accreditation marks, a unique report number verifiable in the laboratory's online database, photographs of the tested sample, a full product description matching delivered panels, and a detailed assembly description (for NFPA 285 or AS 5113 compliance). One-page certificates without supporting documentation are not acceptable. Supplier shall also provide batch traceability documentation linking the report number to the specific panels delivered. Buyer reserves the right to reject any shipment where documentation is incomplete or cannot be verified."

5. The Verification Process (Beyond Documentation)

Step 1: Verify Laboratory Accreditation

Check the laboratory's accreditation status through the accrediting body's online portal:

- NATA (Australia): NATA-accredited facility search

- UKAS (United Kingdom): UKAS CertCheck

- CNAS (China): CNAS database

- NABL (India): NABL-accredited RMP directory

Step 2: Verify Report Number

Enter the report number into the laboratory's verification database. For Intertek-certified products, search the Intertek Directory of Building Products.

Step 3: Verify Product Match

Compare the product description in the report (core type, thickness, alloy, coating) against:

- The product specification sheet

- The delivery documentation

- The physical panels (through burn test, density check)

Step 4: Verify Assembly Match (For System Testing)

       For NFPA 285 or AS 5113 compliance, verify that:

- Insulation type and thickness match the tested assembly

- Attachment method matches

- Air gap dimensions are within the tested limits

Step 5: Conduct Field Testing

        Perform a burn test on a sacrificial panel from each batch:

- A2 mineral core: Does not ignite

- FR core: Ignites with difficulty, self-extinguishes

- PE core: Ignites quickly, melts, continues burning

6. The Legal Consequences of Accepting Incomplete Documentation

The Lacrosse decision established that building professionals cannot delegate their duty of care to product suppliers. The fire engineer was found liable even though they relied on other professionals (architect, builder, building surveyor) to ensure compliance. The Tribunal held that "the awareness of the specialist fire engineer should have been superior".

Similarly, the Design and Building Practitioners Act 2020 (NSW) imposes personal liability on practitioners who sign compliance declarations—even if they relied on supplier documentation.

The principle: Accepting incomplete documentation is not a defense. It is evidence of failure to exercise reasonable care.

7. Legitimate Reasons for Withholding (And How to Respond)

Not all withholding is malicious. Some legitimate concerns exist:

If a supplier cannot provide complete, verifiable fire test documentation, they are not a qualified supplier for any project where fire safety matters.

Conclusion

The refusal to share full aluminum composite panel fire test reports is never benign. It signals fabrication, certificate borrowing, non-accredited testing, assembly limitations, liability exposure, or outdated standards.

For procurement professionals, the defense is systematic verification:

1. Demand full test reports from accredited laboratories—not one-page certificates

2. Verify laboratory accreditation through NATA, UKAS, CNAS, or NABL databases

3. Confirm report numbers in laboratory verification portals

4. Match product descriptions between reports, specifications, and physical panels

5. Verify assembly details for system-level compliance (NFPA 285, AS 5113)

6. Conduct field burn tests on delivered panels

7. Reject any shipment where documentation is incomplete or cannot be verified

The cost of rejecting a non-compliant shipment is a project delay. The cost of accepting one—without verified documentation—is measured in lives, liability, and professional ruin.

When a supplier says they cannot share the full report, they are telling you everything you need to know. Do not buy from them.
