This competence makes Masterflex a technology leader in various fields. Use the QR code on the print version of a press release to get redirected to the corresponding page on PresseBox. Zone 2 is an area in which a potential explosive atmosphere either cannot normally occur or can only momentarily arise during normal operation. Connectors can be included in the grounding on both sides saves additional ground connections. It belongs to the rules relating to risk and encompasses the prevention of spark ignition risk resulting from electro-static build-up.

The occurrence of discharges that can ignite the explosive mixtures of gas, vapour, mist and dust. In addition, the TRBS specifically lists some particularly hazardous areas and gives recommendations for the use of conductive hoses, eg sand blasting work see TRBS 5. Taking into account the groups and areas the following zones result for Equipment Category II all other hazardous areas with the exception of mining which can be presented in a matrix:.

Spiral construction covers the greatest possible portion of the surface in contrast to axial surface-mounted wires. Zone 0 is an area in which a potential explosive atmosphere is present permanently, over long periods or frequently.

When solid and liquid materials are conveyed through chargeable tubes or hoses, electro-static trbs separation of charged particles occurs due to the friction of the material against the wall and the friction within the medium. The surface resistance R O is the electrical resistance measured on the ttbs of an object here hoses.

Our products have proven their worth in application in this regard for a number of reasons: The complete press kit of the company. Hereby it is pointed out that with increasing particle size and lowering minimum ignition energy the ignition sensitivity of bulk solids increases see TRBS Register 6. Such products are designated in the header line trbw the following symbols for grounding capacity and electric conductivity:.

The different categories are required to take 21553 precautions for the prevention of explosions. Antistatic or electrically conductive plastics can be used in manufacture if required.

Masterflex covers the entire process chain from basic research and material selection over developing own trbss methods to production and distribution of hoses and connecting systems. For characterizing the wall material as conductive EC or antistatic AS the volume resistivity R GES may only be used and not the surface resistance, as before. Zone 20 is an area in which a potential explosive atmosphere permanently, over periods, or frequently exists.

Zone 0 electrically conductive hoses such as: By using this website you agree to moreOK. Dangerous or unpredictable behaviour caused by shock when this discharge takes place via the human body. The trbs of the ATEX directives is to be trbs in every European member state within its own national laws and regulations. Vacuum cleaners or de-dusting equipment should also include conductive or dissipative hoses or anti-static see TRBS 5.

Spiral construction covers the greatest possible portion of the surface in contrast to axial surface-mounted tdbs.

How does scanning 253 QR code work? Each operator or handler is responsible and accountable for the appraisal of the potentially explosive area. With regard to the above-mentioned account, we ask you to take into consideration that regulations and rules are regularly subject to changes. The currently frequently used insulating plastic and rubber hoses with conductive metal inlays may no longer be used.

The most reliable protective measure is to prevent electro-static charging in the first place by selection of the proper hose. The TRBS generally restates the status of the relevant technology, occupational health and hygiene rules and other significant occupational scientific findings for:. Since its foundation inthe Masterflex AG has gained extensive knowledge in the field of manufacturing and processing. Hereby it is pointed out that with increasing particle size and lowering minimum ignition energy the ignition sensitivity of bulk trbs increases see TRBS Register 6.

The embedded wire has maximum contact area with the plastic in contrast to externally-applied copper strands. TRBS The ATEX was introduced within the context of the “harmonisation of the European market” to unify the in part strongly divergent national regulations and thus ensure a free and unimpeded exchange of goods and services. While specific resistance is now the yardstick that determines where pneumatic transport can be employed. Taking into account the groups and areas the following zones result for Equipment Category II all other hazardous areas with the exception of mining which can be presented in a matrix: For example, when handling liquids, the limits for hoses are set as follows see TRBS 4.

An explosive atmosphere is always present.

TRBS and BG Chemie T foxiflex GmbH &

Grounding of the hose over its entire length. When dealing with bulk solids the TRBS firstly recommends the evaluation of susceptibility to ignition of the particular bulk solid using the minimum ignition energy MIE. Wire-reinforced hoses made from different thermoplastics, particularly from high-performance polyurethane, open up versatile applications of conveying solid, trbe and gaseous trsb for all kinds of industries.

Recommendations are to employ antistatic hoses with a surface resistivity of As compared to the previous regulation, the new technical rule does not introduce any significant changes as to Zone 2.
