Director of the Royal Polyt. Institute. The Society pledged it-
self to cover an eventual deficit, if the government would
permit the institution to carry the name of the States Testing
Laboratory and would pay a small annual subsidy. In this
manner the States Testing Laboratory was carried on till 1st of
April of the present year, when the government took the entire
charge of the institution, as the minister of the interior the Hon.
Mr. KI. Berntsen, carried through the parliament a law thereof.
A special department of it: the laboratory for clay-
testing which was established by means presented from
Skrikes institution and which had a board of its own
was at this opportunity incorporated in the States Testing La-
boraty.
On page 19, fig. 5 on the right it may be seen how modestly
the States Testing Laboratory began its work in 1896 in
Vestervoldgade 7. Even now it resides very modestly in a hired
flat in Malmøgade 7. The laboratory is technical adviser for the
Danish customs. In some rooms adjoining it the Royal Poly-
technical Institute has its place for training students in the te-
sting of materials.
In the course of the years the Stated Testing Laboratory
has been equipped with the following machines and apparatus:
A complete equipment for cement testing including a 32 Ts.
hydraulic press from Amsler-Laffon, a Ferets bending appara-
tus etc.
A 50 Tons machine for tensile-, compression- and bending-tests
from Tinius Olsen in Philadelphia.
A 120 Ts. Brinck & Hübner hydraulic press.
A machine for testing abrasion, System: Dorry1).
A lever-aparatus for compression-tests of cement- and clay-
pipes.
Besides: An electric furnace (see later) and other furnaces
for testing of clay, a Berthelot-Mahler bomb calorimeter and va-
rious other small apparatus.
Althought the laboratory is thus only modestly equipped with
machines and apparatus when compared with the great institutions
of foreign countries it has however in the course of the years been
able to make tests to an amount of ca. 200,000 Danish crowns
