Additionally, it includes a compulsory temperature cycle procedure. Find out more I agree. To facilitate this decision, let us take a more detailed look at understanding the intentions behind the standards and the actual benefits of using a particular standard to evaluate FE performance.

Customer benefits of fugitive emission reduction Besides the obvious compliance with the ever tightening environmental regulations, also other benefits promote using valves with a low fugitive emission design.

Two different FE leakage limits are set based on the temperature of the application. Still, the basis of the standards lies in the valves themselves.

Fugitive Emissions Test ISO 15848-1

Highly regarded third party certifications are frequently obtained to verify testing conditions and the actual FE performance of valves at Metso. Accelerating the acceptance of ISO certification The biggest challenge for ISO certification adoption so far has been in the wide variety of standards in testing methods and acceptance limits. At the core of TA-Luft, it is revealing that no exact number of operating cycles is defined for the test. Classification system and qualification procedures for type testing of valves ISO It’s easy to join and it’s free.


The new edition release most likely in should include the EPA qualification, which could boost the acceptance of ISOalso in North America, and make the standard a globally accepted one. The flow media for leakage detection is helium, and only global leakage detection methods are allowed. Designing the valves certified according to ISOthe most comprehensive fugitive emission standard today, ensures that they are also compliant with many other emission standards and fulfill the most stringent global requirements.

Emissions are being monitored for just about any product available on the market today, whereas regulations of emission measurements continue to develop under the pressure from society. SmartTag Valve World Automation fair. Students Click Here Join Us! Even if the cost for the leaked medium could be measured in hundreds of euros per year, the lost flow medium results in secondary costs, such as smaller end product yields. Moreover, some standards allow for more interpretation of the test results, and some less.

It is well known that a weak valve design may lose its emission performance after a single heat cycle, setting high demands on the valve design. Consisting of separate parts for prototype and production testing, the flow media for leakage detection is typically helium, although methane can also be used. Foremost, it is good to notice that direct comparison of these standards is challenging, as they all rely on their own testing procedures.

Being already the most comprehensive tool for measuring and realising FE performance objectives, this will be an even stronger incentive for global valve suppliers like Metso to actively pursue a wide range of theoretical and technical knowledge along with the testing and reporting capabilities needed to fulfill current ISO standards classifications.


ISO Class B leakage can be regarded as a standard quarter turn valve performance level. To top it all, the emission limits set out by isi different standards also vary and use differing units.

The flow media used in leakage detection is a hydrocarbon directly from the pipeline, with the detection method being sniffing. Due to these differences and precautions when using methane, leak test results are not strictly comparable.

The most important variables are the test fluids, detection methods for leakage, and leakage limits. Metso in your language.

An additional drawback is the fact there is no predefined temperature cycle procedure. Emission reduction has been a global megatrend for quite a long time. There, the sniffing method is applied and includes three endurance classes for both shutoff and control valve types.

In this way, end users can be sure that they receive high fugitive emission performance with their valves. In TA-Luft, both of these are acceptable to get certification. Close this window and log in.

This is a very practical and intelligent approach, since the individual process plants are thus tied directly to the legislation.

I want know details about what difference between them. First, emission certified valves improve safety and are therefore an health, safety and environment HSE issue as well.
