The QS certification mark can be used in the area of a document that contains the name, logo or address of the laboratory.
However, make sure that the logo is not displayed too prominently in test reports (e.g. regarding the position and size) that have no connection with the QS scheme. The QS certification mark should not be larger than your own company logo. If necessary, you can use the accreditation logo's size and position as a guide in this respect. It must be avoided that if the QS logo is too large, it will be overlooked that the header only shows the range of services of a laboratory in general, independent of the actual laboratory services.
