# Material re-stamping to EN 10204 – re-stamping certificate with seamless material traceability

Transfer material marking to DIN EN 10204 with legal certainty – authorised by GSI SLV München, for fully documented flame-cut and sawn parts from Lorch.
Standard-compliant re-stamping to EN 10204 – verified procedures, equipment and specialist personnel.
Material, heat and sample uniquely linked from the inspection certificate 3.1 down to the single cut part.
Continuous material proof for pressure vessel, plant and structural steel to AD 2000 and DIN EN 1090.
Test basis Pressure Equipment Directive 2014/68/EU, DIN EN 764-5 and AD 2000 Code HP 0.
Cutting to size, re-stamping and documentation at one site – without an external interface.

## What does re-stamping mean?

When a large steel plate is divided into many individual parts, only the remaining plate still carries the original material marking after flame cutting. Re-stamping transfers this marking – material, heat or cast, plus sample and/or plate number – from the original 3.1 acceptance test certificate to DIN EN 10204 onto every single cut part.
This way every part remains uniquely linked to its material certificate even after cutting. You are legally assured that the correct material with the corresponding heat and sample was used for your component – continuous proof for acceptance-relevant parts.

## What is a 3.1 inspection certificate – and how does it differ from a 2.2 test report?

DIN EN 10204 classifies inspection documents by two criteria: whether the item actually delivered is tested (specific testing) or comparable material is tested (non-specific testing) – and whether the result is confirmed by a body independent of the manufacturing department.
The 3.1 inspection certificate according to DIN EN 10204 confirms compliance with the order, stating the results of specific testing, and is validated by the manufacturer's authorized inspection representative, who is independent of the manufacturing department. It thereby documents the material's actual values – heat or cast and sample. Its international designation is inspection certificate 3.1.
The 2.2 test report according to DIN EN 10204 confirms compliance with the order, stating results of non-specific testing, and is validated by the manufacturer. The 2.1 declaration of compliance with the order according to DIN EN 10204 confirms compliance with the order without stating test results and is validated by the manufacturer.
In everyday usage the 3.1 inspection certificate is often loosely called a "mill certificate 3.1" or "works test certificate 3.1". In standards terms it is the inspection certificate under DIN EN 10204 3.1. It is precisely this designation that re-stamping transfers onto every single cut part.

## Authorised by GSI SLV München

## When is a re-stamping certificate required?

Whenever material traceability must be maintained beyond cutting to size:
- Acceptance-relevant parts in pressure vessel and apparatus construction (AD 2000, Pressure Equipment Directive)
- Load-bearing structural steel constructions requiring material proof to DIN EN 1090
- Components from certified materials with an inspection certificate 3.1 that must be proven individually
- Safety-relevant components for crane, plant and vehicle construction
If in doubt, we clarify together which record your project requires – and provide the appropriate documentation.

## Cutting, re-stamping and documentation from a single source

Because flame cutting, plasma cutting and re-stamping come together in the same plant, traceability stays secured without an external interface. We take the material from our own stock, transfer the marking directly at the cut part and document the assignment – one contact, one record, no break in the chain.
On request we combine re-stamping with certified welding to DIN EN 1090-2 EXC3 and non-destructive testing (MT, PT, VT) – the entire quality and verification chain at one site in Lorch.

## Frequently asked questions about the re-stamping certificate

### What is a re-stamping certificate?

URL: https://bock-gmbh.com/en/services/material-restamping/#faq-was-ist-umstempelbescheinigung

A re-stamping certificate is the verifiable record that the material marking – material, heat or cast, and sample and/or plate number – has been transferred from the original 3.1 inspection certificate to DIN EN 10204 onto every single cut part. It serves as proof for audits, acceptances and tenders when a steel plate is divided into many individual parts and only the remaining plate carries the original marking.

### On what basis are re-stamping certificates issued?

URL: https://bock-gmbh.com/en/services/material-restamping/#faq-bevollmaechtigung-geltungsbereich

Bock Maschinenbau is authorised by GSI SLV München to issue re-stamping certificates to standard. The test basis is the Pressure Equipment Directive 2014/68/EU, DIN EN 764-5 sec. 6.2 and AD 2000 leaflet HP 0; the scope covers the transfer of the marking of metallic materials with inspection certificate 3.1 to DIN EN 10204.

### How does re-stamping work in practice?

URL: https://bock-gmbh.com/en/services/material-restamping/#faq-ablauf-umstempelung

The material is taken from our own stock, the marking is transferred directly at the cut part and the assignment is documented. Oxy-fuel cutting, plasma cutting and re-stamping take place in the same plant in Lorch.
