+\section{Introduction}
+
+Regarding to the Kyoto Protocol, the European Union and its members have
+committed themselves to reduce the emissions of refrigerant greenhouse gases,
+like R-134a, during the period 2008--2012. To control the emission of
+refrigerant equipment, it is necessary to check the accuracy of leak detectors
+and room controllers. In the European standard EN 14624 it is pointed out, only
+to use calibrated leaks (called sniffer test leaks) based on a primary
+standard.
+
+\begin{itemize}
+ \item The range of the PTB primary standard is from $4\cdot10^{-11}$ mol/s to
+ $4\cdot10^{-9}$ mol/s which is the most needed range in industry of around 1 g
+ loss per year of the cooling agent R134a.
+

+
+The leakrate $q_{pv}$ is calculated by $q_{pv}= \frac{\Delta V}{\Delta t} \cdot
+p_{atm}$ and the molar flow follows from $q_{\nu} = \frac{q_{pV}}{R\cdot
+T_{wv}}$.
+\end{itemize}
+\section{Measurements}
+There are two types of leaks, capillary and permeation leaks. Both kinds of
+leaks contain the gas R-134a which flow to atmospheric pressure. With the
+following measurements the influence of the fill pressure, the atmospheric
+pressure on the leak rate and stability is examined.
+\begin{itemize}
+ \item The capillary leak is equipped with a pressure reducer and generates a
+ gas flow of $q_{\nu}=8\cdot10^{-3}$\,Pa\,l/s. The measurements did not show a
+ significant dependence on the fill pressure and the atmospheric pressure,
+ however the repeatability is $\pm\,3.4\,\%$.
+
+%%%\includegraphics[width=0.8\columnwidth]{qvonpatmcap}
+
+\item The permeation leak is equipped with a Teflon membrane and generates a
+gas flow of $q_{\nu}=1\cdot10^{-3}$\,Pa\,l/s. In the following graph the mean
+leak rate is shown vs. different fill pressures. The measurements show a
+significant dependence on the fill pressure $p_{fill}$ and the atmospheric
+pressure $p_{atm}$. The slope of the linear least square fit determines the
+atmospheric coefficients $(\Delta q_{\nu}/q_{\nu}(1010\,hPa))/\Delta p_{atm}$ of
+the flow rates. The uncertainty bars show the standard deviation of repeat
+measurements.The permeation leak is equipped with a Teflon membrane and

+
+In the next step, the data were normalized for a gas flow $q_{\nu}$ at an
+atmospheric pressure of 1010\,hPa. Thus the fill pressure coefficients $(\Delta
+q_{\nu}/q_{\nu}(1bar))/\Delta p_{fill}$ could be calculated.

+\section{Results}
+\begin{center}
+ \begin{tabular}{@{}lll@{}}
+    \toprule
+      & capillary leak & permeation leak \\
+    \midrule
+ $(\Delta q_{\nu}/q_{\nu}(1010\,hPa))/\Delta p_{atm}$ & - & $ \leq -0.0063/hPa $ \\
+ $(\Delta q_{\nu}/q_{\nu}(1bar))/\Delta p_{fill}$ & - & $\leq 0.46/bar$\\
+  repeatability & $\pm 3.4 \%$ & $\pm\,0.7\,\% \cdots \pm\,1.6\,\%$ \\
+    \bottomrule
+    \end{tabular}
+\end{center}
+So far, no temperature dependence could be measured due to consistencies
+probably caused by experimental shortcoming.
