1920/1940
Rapid industrial growth
The years between 1920 and 1940 were marked by rapid technological development.
Rationalisation and standardisation were the key words which motivated society.
The major industries - engineering, electrical and chemical - were
all booming.
Society benefited from a succession of inventions and discoveries. In Geneva in
1920 the blueprints for a European Economic Federation were first presented and
in 1936 came the first social rights, with the introduction of the 40-hour
working week and paid holidays.
On 10 March 1925 the Belgian law governing energy distribution entered into
force, granting the local authorities a virtual monopoly, under the aegis of
the Standing Control Committee.

The birth of CEBEC
Electricity use became increasingly widespread as its networks expanded and the
applications multiplied. The need to control the quality and safety of
electrical equipment brought the need for appropriate measures.
This is why, in 1923, the CEB (a non-profit association since 1924) created the
CEBEC mark, the result of several years of careful preparation, allocating the
resources for it to devote itself full time to controlling the safety and
quality of electrotechnical equipment.
International cooperation
In 1909 the CEB took over from the SBI as representative for Belgium on the IEC
(International Electrotechnical Commission), founded in 1906.
The competence and dynamism of the CEB were soon unanimously recognised beyond
Belgium's national borders.
Leading worldwide figures lent their support and encouragement by becoming
honorary members of the CEB : the physicists Thomas Edison in 1920,
Edouard Branly in 1932, and Paul Janet in 1934.
Discovered in the archives
It was with great interest that we rediscovered documents establishing the
awarding of the CEBEC quality mark to two cable manufacturers in 1929 (see
previous page). On 11 July to Fabricable for metal sleeve tubes for electrical
installations and on 17 September to the Câblerie d'Eupen for leaded iron
tubes and steel reinforced tubes.
1931. The first General Regulation
The year was marked by two events :
-
The introduction of the first General Regulation on Electrical Installations.
Still in force today, this regulation was enacted following the Royal Decree of
28 December 1931, pursuant to the law of 10 march 1925.
(Number of articles in the General Regulation : 86 in 1931, 279 in 1998).
-
On 21 December the Belgian Electrotechnical Committee patented the CEBEC
quality mark under No. 40.717.
... Some famous names...
NAGELMACKERS Georges (1845-1905).
Engineer. Founder of the Compagnie Internationale des Wagons-Lits and
originator of the Orient Express. Founder and president of the Belgian Chamber
of Commerce in Paris.
VAN DEPOELE Charles (1846-1892).
Naturalised US inventor, attracted by electricity applications. Founded the Van
Depoele Electric Light Company in Chicago and developed a continuous current
lighting system, a two-phase motor considered to be the first of its kind, an
electric tramway powered by an overhead line and the trolley system.
VIERENDEELS Arthur (1852-1940).
Engineer. Designed internationally renowned bridges all over the world, some
using frame girders.
