Scope of Performance

LV is certified since January 1999 according to European standard DIN EN ISO 9001:2008 / ZertRegNr 01 100 044763. As a certified company you should only work with certified partners.

This is of essential advantage for those users of LV programs working for a pressure vessel manufacturer. The Pressure Equipment Directive recommends or rather requires quality assurance management. The directives of the LV quality management manual are accepted by LV GmbH and will be applied. Manufacturers not working with LV modules have to deal with their calculation programs in their own quality assurance management. LV program users only have to refer to LV's certification.
