There should also be confirmation that the manufacture of the product / system has been carried out under a recognised quality management process.
- For Warranty purposes, where such products / systems are to be used on our sites, they must be clearly identified at the start of a project and a full specification including the third party certification documentation be made available to our Warranty surveyor.
