Packing

Please use the recycling operators known to you. We can also help you – get in touch with your nearest sales office. By agreement

we will take packing material back, if it is sorted. You must bear the costs of transport.

For packing material that is returned to us unsorted or which we are not obliged to accept, we shall have to invoice you for any costs

incurred.

Components used in life-support devices or systems must be expressly authorized for such purpose!

Critical components

of the Semiconductor Group of Siemens AG, may only be used in life-support devices or systems

with the

express written approval of the Semiconductor Group of Siemens AG.

1 A critical component is a component used in a life-support device or system whose failure can reasonably be expected to cause

the failure of that life-support device or system, or to affect its safety or effectiveness of that device or system.

2 Life support devices or systems are intended (a) to be implanted in the human body, or (b) to support and/or maintain and sustain

human life. If they fail, it is reasonable to assume that the health of the user may be endangered.
