Already in 1972 a documented quality control system was introduced. This formed the basis for the quality assurance system which was audited and certified for the first time in 1986 to BS5750. The quality assurance system has been extended and improved step by step since that time. In 1994 LEFFER was certified to ISO 9001 by Lloyd’s Register Quality Assurance (LRQA).
Moreover, LEFFER is a certified Stamp Holder (U and U2) for the fabrication of pressure vessels to ASME VIII-1 and VIII-2.
Quite a few awards have already been granted to LEFFER by its customers for the quality of its products - an evidence that quality assurance at LEFFER does not only exist on paper, but is actively promoted in our customers' interest.
