12.We welcome the efforts of the European Commission to identify possible routes for reverse flow from entry points in existing gas infrastructures, to develop emergency plans for winter 2014-2015 at regional level, and to launch a coordinated action to increase the transparency of gas flows through the Ukrainian network.

Key actions The Commission and Member States should: · Intensify cooperation within the Gas Coordination Group[4] and notably continue monitoring natural gas flows and the level of gas storage and coordinate at EU and/or regional level national risk assessments and contingency plans; · Update the risk assessments and the Preventive Action Plans and Emergency Plans, as provided for by Regulation 994/2010. · Launch energy security stress tests in light of the supply disruption risks in the upcoming winter, and develop back-up mechanisms if necessary; such as increasing gas stocks, developing emergency infrastructures and reverse flows an ...[+++]d reducing energy demand or switching to alternative fuels in the very short term; · Further cooperate with gas suppliers and transmission system operators to identify possible sources for short-term additional supplies, notably LNG.

With these systems, the flow into the transfer tube is matched to the bulk exhaust flow in terms of gas velocity and/or pressure, thus requiring an undisturbed and uniform exhaust flow at the sampling probe. This is usually achieved by using a resonator and a straight approach tube upstream of the sampling point.

'The sampling probe for the test gas flow for particulates must be so arranged within the dilution tract that a representative sample gas flow can be taken from the homogeneous air/exhaust mixture and an air/exhaust gas mixture temperature of 325 K (52 °C) is not exceeded immediately before the particulate filter.`
