Temperature classification (also known as temperature class, or T class) defines the maximum surface temperature that a product destined for use in a potentially hazardous atmosphere is …

To comply with ATEX/IECEx regulations, all equipment and protective systems that are used in hazardous areas must be marked legibly and indelibly with a specific set of letters/numbers.

ATEX Explosion Classification as a “T” value, ranging from T1 to T6 in order of decreasing value (so T6 is “safer”). IEC 60079-0:2011 permits marking a range of certified temperatures with an …

Apr 14, 2016 · t6 85°c This is the lowest temperature at which a gas, vapour or dust will be ignited. If a potentially hazardous explosive gas, vapour or dust is present, the equipment used …

Jan 17, 2019 · Temperature classifications are referred to throughout the design process of explosion proof (ATEX) equipment and are often referred to as T Classes. The T Class is …

T6: Maximum surface temperature of 85°C; The lower the T-class number, the higher the maximum surface temperature allowed. Equipment with a T6 rating, for example, is the safest …

In Europe explosion-protected equipment is classified into cate- gories by EU Directive 2014/34 (ATEX). At international level the equipment protection level (EPL) was introduced by IEC …

Gas and dust groups, typical substances and temperature classifications according to ATEX and IECEx and US and Canadian certification systems.

The ATEX temperature classifications are as follows: T1: maximum surface temperature is 450°C; T2: maximum surface temperature is 300°C; T3: maximum surface temperature is 200°C; T4: …

Different explosive atmospheres (gases, vapours and dusts) will have different properties including flame temperature, minimum ignition energy, upper and lower explosive limits, and …
