Stamp bureau at Charlotte House, Sheffield

Certification stamping from the Sheffield bureau

The six working services of the bureau

AFE Certification Limited operates a stamp bureau and nothing else. Every service below produces a document, a register line or a physical impression that belongs to the client and can be read years after the project has closed. The bureau works from Charlotte House, 500 Charlotte Road, Sheffield - S2 4ER, United Kingdom (GB), and receives files by appointment through the contact desk.

Service mark A

Conformity Ring Audits

A conformity ring audit is the anchor of everything the bureau issues. The ring is the annular seal that surrounds a system enclosure, and it carries far more meaning than a decorative border. It records the tolerance to which the enclosure was built, the surface condition that the certificate assumes, and the identity of the officer who accepted the design. During an audit, the auditor compares the installed ring with the specification held on file, traces the inner and outer annular bands, and records any deviation in the workbook. Where the enclosure has been assembled from components supplied by different vendors, the audit also confirms that the ring has travelled with the correct batch and has not been substituted at a late stage.

The finding of a ring audit is written in plain language and is deliberately conservative. If a feature falls outside the tolerance, the auditor states the measured value and the permitted range rather than offering an opinion on whether the difference matters. Clients receive a copy of the workbook page and a short summary that can be handed to a procurement team. Audits are performed at the bureau where the system can be transported, and by appointment on site where it cannot.

  • Measurement of inner and outer ring tolerance against the issued specification.
  • Verification of ring identity across multi-vendor assemblies.
  • A signed workbook page retained for the life of the register line.

Register Entry Desks

The register entry desk is where a finding becomes official. Once an audit is complete, a clerk transcribes the result into the register, assigns the mark, and enters the date, the officer name and the scope of the certificate. The desk is staffed by two officers working in sequence, so that no entry is ever written by a single hand. This separation is the bureau promise: a register line is only as trustworthy as the discipline that produced it, and the double transcription is how that discipline is enforced.

Because the register is the long memory of the bureau, the desk takes care with the small things. Abbreviations are avoided. Dates are written in full. Where a file has been amended, the amendment is appended rather than overwritten, and the reason is recorded alongside it. Clients can request a certified extract of their register line at any time, and the extract carries the same mark as the original certificate. The desk also closes files, which means it confirms that every obligation attached to a mark has been met before the record is retired.

  • Assignment of the register mark and the certificate scope.
  • Sequential double transcription to guard against clerical error.
  • Certified extracts for procurement, handover and archive.
Service mark E

Stamp Plate Runs

A stamp plate run produces the physical impression that appears on the certificate sheet and, where the client requests it, on the equipment label. The bureau cuts the plate from a brass die that matches the current register mark, then proofs the impression on vellum before any certificate is touched. Proofing exists to catch the two failures that matter most: a plate that is legible at one size but illegible at another, and a plate that will not hold its edge across the surfaces the client intends to mark. Only after the vellum proof is accepted does the run proceed to the press.

Plate runs are recorded in the same way as audits, with the plate number, the die used and the proof retained in the file. Clients receive a proof card alongside the finished sheet so that a future enquiry can compare the impression on their equipment with the impression the bureau intended to issue. When a plate wears out, the replacement is treated as a new run and is logged with the date of the original, which keeps the register honest about the age of any mark still in circulation.

  • Plate cutting from the brass die held under the current mark.
  • Vellum proofing before the press is released.
  • Proof card returned with every finished certificate.
Service mark C

Site Visit Certificates

Some installations cannot be judged from drawings. A site visit certificate is issued when the bureau officer attends the installation and records the conditions found on the day. The visit is not a general inspection: the officer is there to confirm the matters that the certificate will depend on, such as the condition of the ring in place, the clearance around the enclosure, and the accessibility of the label that carries the mark. Photographs accompany the written record, and anything that would limit the scope of the certificate is noted in a short limitations paragraph.

The visit certificate is a standalone document that refers back to the register line rather than replacing it. This structure means that a client who later moves the equipment knows immediately whether the certificate still applies, because the visit record names the location and the date. Officers agree the visit window with the client in advance and arrive with the workbook already prepared, so that the time on site is spent observing rather than writing from scratch.

  • Attendance by a named bureau officer on an agreed date.
  • Written record of ring condition, clearance and label access.
  • Limitations stated plainly so that the certificate is not overread.

Renewal Mark Checks

A mark is a claim about a moment, and the renewal mark check is how the bureau keeps that claim current. When a mark approaches the end of its cycle, the holder submits the equipment and the existing certificate for re-examination. The officer compares the ring and plate with the register as it stands today, confirms that the holder remains entitled to the impression, and decides whether the plate is still serviceable. Where nothing has changed, the register line is extended with a renewal note. Where something has changed, the file returns to the audit desk for a fresh ring measurement.

The renewal window is announced in advance so that holders can plan around it. The bureau keeps the check deliberately blunt: a mark that no longer reflects the register is not extended on the strength of long use, and a plate that has begun to blur is not carried forward because a replacement would be inconvenient. This bluntness is the reason the ring retains its value, and holders who renew on time receive a renewal card that records the check alongside the original mark.

  • Re-examination against the register as it stands on the check date.
  • Renewal note added to the existing register line.
  • Renewal card issued to the holder for the next cycle.
Service mark D

Discrepancy Hearings

Discrepancy hearings exist for the case where the record and the equipment disagree. The hearing is a formal but short proceeding at which the holder, the auditor and a chair review the evidence in sequence. The chair may call for a re-measurement, examine the original workbook page, or ask the plate room to produce the proof that was retained at the time of issue. The panel issues a written finding that either restores the mark, records a correction, or withdraws the mark with a stated reason.

Hearings are rare, and that is the point. They are the safety valve that allows the bureau to correct itself without weakening the confidence that clients place in the register. A finding is entered in the same register that carries ordinary marks, so a correction is visible to anyone who reads the file. Holders receive a copy of the finding and a short note explaining what, if anything, they must do next, together with the deadline for any re-certification.

  • Short formal proceeding chaired by an independent officer.
  • Access to original workbook pages and retained plate proofs.
  • Written finding entered in the register and issued to the holder.

Renewal mark checks are scheduled across the working week at Charlotte House, and holders are reminded that a mark which has passed its renewal window can no longer support a fresh certificate.

How the process runs end to end

A file begins at the contact desk, where the client states the system boundary and the documents that already exist. The desk confirms whether a ring audit alone is sufficient or whether a site visit will be required, and it books the audit window. When the audit is complete, the register desk assigns the mark and transcribes the finding. The plate room then cuts and proofs the impression, and the press is released once the vellum proof is accepted. The certificate is issued with its mark, proof card and renewal date, and the register line remains open for the life of the certificate.

Clients are welcome to attend at any stage, and many choose to watch the press, because the physical impression is the clearest illustration of what the bureau actually does. The whole journey is usually completed within a single working cycle for straightforward files, while multi-vendor systems with a site visit naturally take longer. The bureau never shortens the audit to meet a date, and it says so at intake rather than later.

If you would like to open a file or ask which service fits your system, the contact desk at Charlotte House will confirm the next available appointment.
