The implementation of a quality-assurance system in our steel companie
s according to the Standard Series EN 29000-29004/ISO 9000-9004 requir
es also the auditing of suppliers. As the member companies of the VDEh
are organized in technical committees for the exchange of experience
and for the processing of topical problems, the auditing of suppliers
within the scope of the VDEh cooperative work is the most economical a
pproach. For this purpose, a working group ''Auditing of blast furnace
and steelworks suppliers'' has been set up. This report describes the
preparation, performance and evaluation of the audits. The mutual acc
eptance of successful audits by the steel companies involved in the wo
rking group leads to time and cost savings both for the steel companie
s and the suppliers. The experience gained until now shows that the su
ppliers attach great importance to the cooperative audit accepted by a
ll the steel companies involved in the working group and consider it t
o a large extent a ''must'' to belong to the circle of companies which
have been or are to be audited.
