  This is to certify that the vacuum gauges and/or test leaks (including their
  vacuum components) which we ordered to being calibrated by PTB
  \begin{itemize}
    \item are not contaminated with toxic, corrosive, explosive, radioactive,
    microbiological, carcinogenic or other harmful substances,
    \item were investigated with respect to their operational reliability before
    shipment to PTB,
    \item leave our house in a condition according to the general rules of high
    and ultrahigh vacuum techniques (not applicable for sniffer leaks) and in a
    condition that a contamination of the PTB calibration standards can be
    excluded (e.\,g.\ by oil or other hydrocarbons),
    \item are ready for calibration from the metrological point of view,
    \item obey the general rules of prevention of accidents and the
    acknowledged rules of relevant techniques and
    \item that we have no knowledge of any other indication of obstacles to a 
    calibration.
  \end{itemize}

  Transport shall be organised in the following manner\footnote{%
  Any costs related to transport and customs clearance have to be paid by PTB’s
  customer. For equipment from customs area outside EU an ATA carnet is 
  required.}:

  \begin{itemize} \renewcommand*\labelitemi{$\Box$~}

    \item Please, use the regular PTB shipping agent (PTB cannot insure 
    transport!).

    \item Please, use the following carrier\footnote{%
      If customs clearance is necessary, it may not be possible to use your
      carrier chosen. In normal cases, customs clearance has to be made by the
      local carrier that organised the local transport to PTB.
