9.2 INFICON Service
If equipment is returned to INFICON, indicate whether the equipment is free of subs-
tances damaging on health or whether it is contaminated. If it is contaminated also
indicate the nature of the hazard. For this you must use a Declaration of Contami-
nation form Fig. 1-1 which has been prepared by us which we will provide upon
request or you may copy the form which has been reproduced on the next to the last
page of this handbook.
Please attach this form to the equipment or enclose it with the equipment.
This Declaration of Contamination is required to meet German Law and to protect our
personnel. INFICON must return any equipment without a Declaration of Contami-
nation to the sender’s address.
