Quality Statement
Product quality and safety in use are of paramount concern to us. It is for this reason that registration to the approved quality standards was sought. Accreditation was first achieved in 1997, and we are proud to announce that we now hold the latest revision, ISO.9001:2008. As a logical and essential development of our ongoing commitments we sought and achieved registration to the environmental standard ISO:14001 in 2002.
