TSEK Preparation: Technical Criteria and Performance Claims

Assess measurable product characteristics, manufacturing locations and claims together. This guide explains practical scope questions in a TSEK application.

Questions for your situation

Do TSEK criteria cover every way the product could be used?

Compare the criteria's scope with intended use and product characteristics. Results do not automatically extend to other environments or applications. Describe actual limitations and variants in the application. Clarify uncertain technical boundaries with TSE before expanding catalogue claims.

Which records connect an applicant to a separate manufacturer?

Show commercial relationships, brand rights, factory identity and access to technical and production-control records. Samples should be traceable to their manufacturing site and method. Responsibilities must match TSE application conditions. A sales agreement alone does not establish technical capability.

Will an existing laboratory report be accepted directly for TSEK?

Check method, model, version, sample and required technical coverage. Acceptance follows the TSE programme's conditions. Tests conducted for another purpose may leave criteria unaddressed. Mapping reports to requirements before commissioning additional tests improves time and cost planning.

What if the material changes but the commercial product code stays the same?

An unchanged code does not remove the technical change. Assess affected characteristics and necessary retesting. Maintain traceable batches and change dates. Do not apply old sample results automatically to new material before meeting TSE notification or scope-update conditions.

How should marking on stock be handled after certificate expiry?

Consider manufacturing dates, certificate conditions, marking rights and the reason certification ended. Do not assume either unrestricted use or an automatic prohibition for all stock. Clarify the case under TSE agreements and current instructions. Sales claims about valid certification must reflect actual status.

Is TSEK sufficient when a customer's specification requests TSE?

Examine the exact specification and acceptance conditions. Different certification bases should not be assumed equivalent. Written clarification from the customer may be needed. Technical similarity alone does not satisfy a contractual document requirement; resolve this distinction before quoting.
