What is CE and why should you insist on it?

CEEN14889-1 is currently the only performance based manufacturing standard for steel fibres.

Manufacturers’ are required to declare a fibre dosage needed to meet a certain performance level which is audited by an independent auditor. Every pallet must have a CE label that details the manufacturing facility and this Declaration of Performance

Under the requirements of CE certification all manufacturing facilities must be independently audited. These auditors certificates must be made available to ensure transparency and traceability. All Dramix steel fibres have CE and are independently Audited. Here is a link to our Auditors certificates from the Auditors website:

NB no.  0749 – BCCA Belgian Construction Certification Association

This certifies that the fibres are manufactured in accordance with EN14889-1, system 1 for structural use.  If a manufacturer cannot provide this document then their production QC and declared values (fibre tensile strength, diameter, etc.) are not third party verified and not of a reliable performance.

Typical specification for designers:

  1. Fibres should be manufactured in accordance with EN14889-1, system 1 for structural use. A copy of the CE Auditors Certificate must be provided to the project engineer.

(If documents are not requested, then there is no way of ensuring compliance)
