The ignition properties of the hazardous explosive atmosphere shall be determined. Relevant data are, e.g.:

a) minimum ignition energy (see EN ISO/IEC 80079-20-2);

b) minimum ignition temperature of an explosive dust atmosphere (see EN ISO/IEC 80079-20-2);

c) auto-ignition temperature of an explosive gas atmosphere (see EN ISO/IEC 80079-20-1)

See more EN 1127-1:2019

Keep up good work!
