Parker Instrumentation is launching a range of instrumentation manifolds meeting the stringent new ISO15848 standard for fugitive emissions.

Available in double-block-and-bleed configurations, in monoflange or low-profile flange-ended forms, the new manifolds provide process instrument interfaces of outstanding integrity to help organisations dramatically enhance their LDAR (leak detection and repair) programmes.

Published in 2006, ISO15848 parts 1 and 2 (defining a classification system and qualification procedures, and production acceptance test of industrial valves, respectively) specify new ultra-low standards for emissions, which are attracting the attention of oil, gas and chemical/petrochemical organisations worldwide.

The standard is mainly used for process valves, but is now starting to be widely considered for instrumentation-sized components as well, especially on environmentally sensitive projects.

Parker Instrumentation's Kevin Ballard states: "Interest in ISO15848 is progressing from the process valve to the instrumentation arena, and we are delighted to enter the market early in the cycle. With increasing environmental regulation, we expect the demand for ISO15848 compliance, which effectively sets a 'zero emissions' standard, to soar in the coming decade."

There are three leakage classifications specified by ISO15848: A, B and C (specifying maximum leakage rates from less than or equal to 1x10-2mg/s/m, to a figure four orders of magnitude less: 1x10-6mg/s/m. Meeting any of these low levels is a challenge, which Parker Instrumentation has solved with new ball and needle valve designs for use in double-block-and-bleed instrument manifolds.
