Material Test Certificates and its Traceability

A) Certificates of conformity

Customers are keen to have suppliers confirmation, in writing, the quality of goods supplied and the materials from which they are produced. Validation of quality provided through the Mill Test Certificate is meant to give a declaration, in writing, that the goods are as ordered, and therefore are meant to give a degree of confidence that they are fit for purpose.


Certificates acc. DIN 10204

The European standard Norm EN 10204 defines different types of test document which can be made available to the buyer for each delivery in compliance with agreements concluded on placement of order.
This standard supplements other standards which define the general technical terms and conditions of supply.

We can supply you with the following types of test certifications in accordance with EN 10204:

Type of certificate Designation Content Tests Confirmation
2.1 Works certificate acc. 2.1
Confirmation of agreement with the purchase order No test results Compliance with agreements
2.2 Works certificate acc. 2.2 Confirmation of agreement with the purchase order specifying the results of non-specific tests Guideline values, tested on a semi-finished product made using the same material, e.g.: -Density -Melting point Compliance with agreements
3.1 Acceptance certificate acc .3.1 Confirmation of agreement with the purchase order specifying the results of specific tests Mean values, tested at a semi-finished product* from the same production** e.g.: -Density -Melting point -Tensile strength -Tensile elongation at break -Impact strength Compliance with agreements
Declaration of conformity Declaration of conformity Certification of a certain material property No test results Compliance with agreements

* or of the input material, if the required test data or material samples are available
** Test data originates from the production of the supplied material


Works certificate in accordance with 2.1


Certificate in which the manufacturer confirms without indicating the test results, that the supplied products comply with the requirements of the purchase order and the specified standard of quality.


Works certificate in accordance with 2.2

Certificate in which the manufacturer confirms with an indication of the test results, that the supplied products comply with the requirements of the purchase order and the specified standard of quality.


Non-specific tests which are intended to determine whether products manufactured in accordance with the same product specification and using the same method, comply with the requirements set out in the purchase order. The tested products do not necessarily have to originate from the delivery itself, but can originate from different comparable production processes.


Acceptance test in accordance with 3.1


In an acceptance test certificate in accordance with 3.1, the manufacturer confirms, with indication of the specific test results, that the delivered products comply with the requirements specified in the purchase order. The acceptance test certificate is confirmed by an acceptance officer of the manufacturer who is independent of the production department.

In the acceptance test certificate in accordance with 3.1,


the manufacturer is permitted to adopt test results which were determined on the basis of specific testing of the input material or semi-finished products used. However, this is only possible with the proviso that the manufacturer uses methods to ensure traceability and is able to submit the relevant test certificate. Otherwise, the test results are determined from cut test specimens from the relevant semi-finished production batch.

Test costs are incurred for an acceptance test certificate in accordance with 3.1 (depending on the required test results). In addition, we levy a handling charge.



Declarations of conformity


These are documents providing a declaration on whether the material or the input material used in its production possesses a certain property.


B) Traceability


Traceability of products and/or materials is meant to help any investigation into “what went wrong”, in the event of a problem, through the recording and storing of relevant details for future reference. Levels of traceability can be very precise, down to the exact time of manufacture, from the most detailed chemical properties of materials, to the inspection, testing and subsequent acceptability of assemblies. It may be sufficient to record, in what year a product was manufactured, or whether it was produced before or after a certain batch of material was used.

The extent or levels of implementation are dependent on an estimation of the criticality of the products and the cost of collating and archiving records, balanced against the likelihood of future product failure and resultant consequences. Traceability is not a single direction activity and, if managed well, will provide any investigation with the means to trace through production, inspection and test records of items, from end user to source supplier or vice versa.

A Traceable Certificate includes all of the information to meet today's stringent accreditation demands, This information includes Certificate No. & Date, Description of items, Technical Specn. of items, Heat Number, Manufacturer’s name, Process of Manufacture, Test Results (Chemical Analysis & Mechanical Properties), Qty. in Pcs and Mtrs. and signature of the QA Department and details of disposal . The information, presentation, and completeness of data provided on the Traceable Certificate are all protected.
