The BIPT conducted an audit to verify whether the BELEX measurement system, that monitors the quality provided by bpost (the Belgian universal service provider), complies with the provisions of European standards EN 13850 and EN 14508.
As non-conformities were identified during this audit, the BIPT decided to organise its own quality snap shot -i.e. “BIPTlex delivery experiment study”- in order to gain additional insight into the quality achieved by the universal service provider.
It was decided to focus on three products, namely priority and non-priority letters (with stamps) and obituary mail.
Of each category, 400 items were sent in order to be sure to meet the required sample size. This dispatch of these letters took place between 9th and 25th of September 2025.
After the study was completed, BIPT received a request from bpost to adjust for the impact of several days of mail delivery disruptions caused by strikes; the (limited) effect of this on certain results of the study was discussed in the press release.
