TCAB carries out an audit to establish compliance with the Customer's Trust Electronic
Services Management System, according to EU Regulation 910/2014 (eIDAS), based on
the standards and, according to the proposed scope and program described below:
Standards of application:

  • EN 319 401
  • EN 319 411-1
  • EN 319 411-2
  • EN 319 421

The audit would be performed in three stages:


The audits are performed with an Audit Plan, that will be made by the audit team every year. In this Plan, the audit data are settled (date, lasting, scope, points to be audited, audited area, contact persons…) and checklists (date, time, points  of the standards to be audited, audited area, contact persons,
auditors). In order to prepare it, reports form other audits already performed will be
Once it is made, the audit plan will be revised and approved by the Technical Committee.


To start the audit, an initial meeting with the client will be held to confirm the scope of the audit, the data collected in the Audit Plan, stablish a sequence of the audit and discuss those points that both parts believe necessary. After this step, the audit will start following the Audit Plan as a work guide. There are two steps at this point:

  • 1. Document Review: We will check the system conformity (documents, registers…) through the accomplishment of the points of the reference standards/laws. The resolution of possible non conformities of  previous audits will be verified.
  • 2. On-site Inspection: Proofs of accomplishment of the established controls will be performed. A sampling inspection of the objective evidences will be held in order to test the correct operation of technical and organizational processes related to the scope of the audit. The resolution of possible non conformities of the document
    review will be verified.

If the audit would be performed as a consequence of the presence of non conformities, our team will deepen in the causes and effects and will define a corrective/preventive action.
Once the audit is finished, the audit team will write a report of results, identifying in a clear and defined way the detected non conformities.

Next to this, there will be a final meeting where the audit team will show the report to the client, so that he/she can review and sign it. In those cases where there is no presence of significant non conformities, a new date for the next audit  will be programmed to check the removal of those non conformities.
It is mandatory to submit the CAR (Conformity Assessement Body) to the Supervisory Body within 3 days after receiving it.


The audit team shall submit the audit report to our Technical Commitee for review, and either a Certificate will be issued or an extraordinary audit will take place.
ARCHIVING PERIOD: The audit reports and documentation about Non Conformities will be stored by TCAB.
