Intrinsic safety certification refers to the explosion-proof certification of intrinsic safety. The following is a detailed introduction to intrinsic safety certification:
The basic definition of intrinsic safety:
Intrinsic safety refers to limiting the circuit energy of electrical equipment so that the electrical sparks or thermal effects generated during normal operation or specified fault conditions cannot ignite the surrounding explosive environment. This explosion-proof type mainly starts from limiting the energy in the circuit, reducing the potential spark energy to below the specified ignition energy of the gas mixture, and limiting the surface heating temperature of the wires and components to below the specified ignition temperature of the gas mixture, thus achieving intrinsic safety
Scope of application of intrinsic safety:
Intrinsic safety certification is widely used in some low-power and low-energy instruments, handheld terminal products, etc. Because the energy generated by these devices is relatively low, it is easy to control them within a safe range through technological means to meet the requirements of intrinsic safety. For example, products such as temperature vibration sensors, remote control transmitters, methane monitoring devices, Bluetooth beacons, walkie talkies, etc. can all undergo intrinsic safety certification
Certification standards for intrinsic safety:
The main implementation standards for domestic intrinsic safety certification are GB/T3836.1 and GB/T3836.4. The international IECEx certification standards are IEC60079-0 and IEC60079-11. These standards provide detailed regulations on the technical requirements, test methods, inspection rules, and other aspects of intrinsic safety electrical equipment to ensure the intrinsic safety performance of the equipment.
Required documents for obtaining intrinsic safety certification:
Including product manuals, enterprise standards, electrical schematics, schematic diagrams, PCB diagrams, assembly drawings, exploded diagrams, battery specifications, encapsulation process documents, wireless transmission power reports, shell material reports, etc.
The significance of intrinsic safety certification:
Equipment certified by intrinsic safety can minimize the risk of explosion and ensure the safety of personnel and property when used in hazardous environments such as flammable and explosive environments. Meanwhile, for enterprises, obtaining intrinsic safety certification is also one of the important entry conditions for their products to enter the relevant market, which helps to improve the market competitiveness of their products.
