Separate three kinds of evidence
A dimensional drawing can establish how the proposed panel is constructed. A test report records what happened to identified specimens under a stated method. A certificate relates a listed product or system to the scope of a certification scheme. These documents can support one another, but they should not be treated as identical.
Accreditation is another term with a different meaning. UKAS explains its role in assessing organisations that perform conformity-assessment activities, including testing and certification. Accreditation of a laboratory is not a certificate for every fence that laboratory tests. See the UKAS explanation.
For a purchasing decision, write down the claim first: mesh dimensions, coating performance, forced-entry resistance or another requirement. Then ask which document demonstrates that claim for the item being offered.

Read beyond the certificate heading
A useful scope review compares the manufacturer, product reference, dimensions, posts, connections and gate configuration with the order. Pay particular attention to allowed variations and the documents incorporated by reference. A familiar logo on the cover does not resolve a mismatch in the assembly.
The LPCB RedBook Live listing for one certified gate range, for example, separates opening arrangements and records dimensional limits, locking-system references and ratings. It illustrates the level of product identity involved; it is not evidence for a FencingWise product or a substitute gate.
Do not copy a listed rating onto an unlisted fence because the infill looks similar. Nor should a buyer assume that every product from a certified manufacturer is covered by the same certificate.
Work through a hypothetical substitution
Imagine a tender requiring a certified assembly identified as System X. Its referenced documents specify a panel, post, fixing arrangement and permitted height range. A supplier offers the following changes:
| Item | Proposed difference | Procurement decision |
|---|---|---|
| Panel | Same nominal mesh opening, different wire specification | Coverage unresolved; compare the permitted construction |
| Post | Different section to reduce freight weight | Do not presume the original certificate covers it |
| Connections | Fewer fixing positions | Obtain evidence for the proposed configuration |
| Gate | Similar mesh, another frame and lock | Review the gate evidence independently |
| Height | Within the stated range | Still check the other scope conditions |
These are invented review examples, not descriptions of a real certificate. The correct result is not an improvised rating calculation. It is a documented decision by the issuer or responsible project authority on whether the proposed changes are covered and acceptable.
Five matching dimensions cannot cancel one unapproved change. Avoid scoring scope compliance as a percentage and treating a high score as sufficient.
Verify the document at its source
- Locate the issuer's current register or verification service.
- Match the certificate number and legal manufacturer name.
- Obtain the certificate and relevant scope schedule, not only a cropped image.
- Check status, issue information and any withdrawal or suspension notices.
- Compare the quoted product and drawing revision with the scope.
- Record unresolved differences and the written response before release.
Save the date of the check and the document revision in the procurement file. Evidence can change after an early tender review, so repeat the status check when the actual order depends on it. A reseller's product description is useful identification but is not the issuing body's confirmation.
Avoid transferring claims between security functions
Forced-entry resistance, vehicle impact, electrical safety and ball retention concern different duties. A fence assessed for one does not automatically satisfy another. The same applies to coating tests and structural calculations: they may be necessary parts of the package without establishing its security classification.
A complete perimeter also includes gates, corners, ground details and operating arrangements. Product evidence should be preserved within that design, rather than used as a general promise that a site is secure.

What an honest quotation should say
An unclassified assembly should be described by its verified construction and intended application, without borrowing a certified-system rating. Where a tender requires evidence the supplier cannot provide, show the gap clearly and resolve it before acceptance.
FencingWise does not use other manufacturers' certificates to prove its own product performance. Use the test-document guide to organise available records, and keep any mandatory rating as an explicit selection condition in the order.
