3_APPLICATION OF RESEARCH FINDINGS, TIES WITH INDUSTRY AND EXPERT APPRAISALS
In 2011, the group conducted chemical tests on 387 additives
and 11 curing products and physical tests on 39 additives
and 2 curing products. In addition, it organized and
analyzed the results of the intra- and inter-laboratory tests for
COFRAC in order to determine the measurement uncertainties
of the chemical tests.

Line 1 on the Algiers metro line
Early November 2011 saw the opening of the first metro
line in Algiers.
After two years of work supporting the rail certification
agency CERTIFER, ESTAS approved the safety demonstration
documents for the Siemens France automatic driver system.
This is the second heavy metro system to be built in Africa and
ESTAS had already carried out the expert appraisal for the first,
in Cairo, in the 1990s.
On the Algiers line, CBTC (Control Based Train Communication)
devices automatically control train driving, compliance
with speed limits, headways and stopping points, with the
human driver only operating the doors and giving the authorization
to leave the station. The principle is for the automatic
devices on the train to transmit the exact position of the train
to the automatic devices on the ground on a continuous basis.
The equipment on the ground determines the stops the train
must make to guarantee safety and transmits them to each
train. The individual trains then optimize their speed in order to
ensure safe movements and compliance with operating goals.
The technology uses massive coding of data and implements
safety-critical software developed and tested using formal
methods (method B).
