The simple answer is to make sure the measuring is done correctly
EN 60079-29 series standards specifies general requirements for construction, testing, performance, selection, installation use and maintenance for flammable gases and oxygen gas detection and measurement systems. It also describes the test methods that apply to portable, transportable and fixed apparatus for the detection and measurement of flammable gas or vapour concentrations with air.
This standard is applicable to flammable gas detection systems intended to provide an indication, alarm or other output function for the purpose of warning of a potential explosion hazard. These systems are expected to initiate automatic or manual protective actions in case of any potential hazard. Hence generating alarms and providing outputs in correct level is very important.
EN 60079-29-1 is intended to provide for the supply of apparatus giving a level of safety and performance suitable for general purpose applications which known as performance approval. Basically it will provide trust to you when asked “are you sure the correct gas concentration is displayed?”. It also provides metrological compliance for the gas detection system. Metrological compliance is necessary for all measurement systems.
According to the ATEX directives any gas detection system that used as safety device to reduce the risk of explosion has to be performance approved. This approval includes detectors and control panels as well. The EC type test certificate must show compliance according to EN 60079-29-1 for ATEX. As the standards are continuously evolves, earlier version of standard’s (EN 60079-29-1:2007) harmonization is expired at December 2019 and gas detection systems must comply to latest harmonized version of standard EN 60079-29-1:2016.
Prosense closely monitors the industrial standards, apply rules into devices and always comply them. You can be sure with Prosense what your detector is measuring. Prosense provides performance approved gas detectors to make life safer.
