The iron and steel (I&S) sector plays an active role in
the world economy with a market share of an estimated $1,715
billion. As in other sectors, qualified production is a crucial step
for international trade for I&S sector. For example; between the
years 2013-2015, two major steel-producing countries of Turkey
and Germany have reacted differently against the low quality
steel sale from China. While the poor quality steel produced by
China has no place in the German market, it has played an active
role in the Turkish market. From this point of view, the effects of
the accredited laboratories on the sectors they serve were
examined by means of the iron and steel industry. The trend of
the accredited laboratories in Turkey serving the iron and steel
industry has been investigated in detail. In addition, the results
were compared with Germany.

Reference materials (RMs) are one of the basic
materials used by the laboratories to prove the reliability of their
test results. In this research, preliminary studies have been
carried out to develop reference materials (RMs) according to
ISO 6892-1 tensile testing standard. For this purpose, EN
10130:2006 quality 1 mm thin sheet steel was prepared as
appropriate to standard. Homogeneity tests and inter-laboratory
comparison tests were performed. Results of these tests and
reproducibility criteria that specified in ISO 6892-1 were
evaluated to understand the qualification of the produced RMs.
It was considered that samples can be accepted as RMs with the
application to IAF member organizations.

In this study, it was investigated whether there was a
correlation between the production of steel and the number of
accredited laboratories of countries. For this purpose, the
metallic material competence (MMC) coefficients of countries
were calculated. According to the results, Germany, known as a
quality steel producer, was the country with the highest
coefficient. Moreover, Germany's made in country index has the
best value in other countries. However, China, which is the
market leader in steel production, was a country with the lowest
MMC coefficient among the compared 10 countries. It was
foreseen that countries should focus on non-destructive tests in
order to become quality steel producers. This study for the iron
and steel industry was thought to be a guide for other sectors.
