Explosion proof certification is used to determine whether equipment complies withExplosion proof standardThe work of conducting requirements, type tests, and routine tests for adaptation, and issuing relevant certificates of conformity. The certificate can be for Ex devices or Ex components.

The equipment here includes:

(1) Equipment: refers to machines, instruments, fixed or mobile devices, control components, and instruments used in potentially explosive environments

(2) Protection system: refers to a product used to prevent an immediate explosion or limit the range of flame or pressure effects generated by an explosion

(3) Component: Explosion proof components without independent functions, their performance must be evaluated together with explosion-proof equipment, such as explosion-proof enclosures, wiring terminals, etc.

As a general term for various wires used to transmit electrical and optical signals, communication cables do not belong to independent electrical equipment or mechanical equipment, and do not generate arcs or sparks in normal working conditions.

Even when used in explosive hazardous environments, it is not necessaryExplosion proof certificationof Usually, communication cables used in explosive hazardous environments only need to consider their surface resistance, static electricity, and other properties, and only need to provide performance test reports that meet relevant standard requirements.

However, if the communication cable is used underground in coal mines, it can be applied forCoal safety certificationof
