Scope

This part of "Explosive Atmospheres" specifies test methods for the determination of combustible dusts and combustible dust layers. It is used to classify sites where such substances are present in order to correctly select and install electrical equipment and non-electrical equipment for combustible dust environments. Equipment (machinery equipment, etc.). The measured combustible dust characteristics are applicable to the following environmental conditions: 　——Temperature: 　——20 people to 60Ci - Pressure: 80kPa -11010 (ratio): usually 21%%. The test methods specified in this section do not apply to: 　——known explosive substances, propellants (such as gunpowder, propellants), or substances or mixtures with similar properties under certain conditions; or - do not require atmospheric Oxygen is a flammable explosive substance or propellant.
