ok gus, maintenance costs etc might be a little higher, but why are you worried about ISO9000 qualification ... because they use machines being "out of date" ? Regarding ISO9000 it does not matter what type of machinery they use or even how old they are ... ISO9000 is a standard or a "guaranty" to proof a third party (in most cases this is the customer) that all your internal operating procedures (or workflow) are logical, optimized and documented in order to ensure a certain (and more important a constant) product-quality, right ?
Take care and stay SaVi
