The full name of GB4943 standard is "Safety of Information Technology Equipment", which is a mandatory national standard designed to ensure that information technology equipment will not cause harm to personal safety and property safety during use. This standard specifies the electrical, electromagnetic, mechanical, thermal, and fire safety requirements for information technology equipment to ensure that the equipment remains safe under both normal and abnormal working conditions.
1. Electrical safety.
Electrical safety is the most important part of the GB4943 standard, which specifies the electrical safety requirements for information technology equipment. These requirements include grounding measures, electrical insulation, withstand voltage, leakage current, contact current and other indicators that the equipment should have to ensure that the equipment will not be exposed to dangerous situations such as electric shock and electric shock during use.
2. Electromagnetic compatibility.
Information technology equipment generates electromagnetic radiation during operation, which may cause interference or harm to other equipment or the human body. The GB4943 standard stipulates the electromagnetic compatibility requirements for information technology equipment, including electromagnetic radiation, conducted interference and other indicators, to ensure that the equipment will not cause adverse effects on the surrounding environment during use.
3. Mechanical strength.
Mechanical strength is a requirement for the structural stability of equipment in the GB4943 standard. It stipulates that the shell and internal structure of the equipment should have sufficient mechanical strength to withstand external forces such as normal operation and accidental collision, and will not be deformed or damaged, so as to ensure the safe use of the equipment.
Fourth, thermal safety.
Thermal safety is a requirement for the heat dissipation performance of devices in the GB4943 standard. It stipulates that the heat-generating parts of the equipment should have sufficient heat dissipation capacity to operate stably within the normal operating temperature range, and the shell of the equipment should have sufficient heat resistance to withstand the effects of high-temperature environments.
5. Fire safety.
Fire safety is a requirement for the fire performance of equipment in the GB4943 standard. It stipulates that the materials and structure of the equipment should have sufficient flame retardant performance to delay the spread of fire in the event of a fire, and at the same time, the interior of the equipment should be equipped with protective measures such as fire alarm and fire extinguishing, so as to be able to alarm and take countermeasures in time when a fire occurs.
To sum up, the GB4943 standard, as a safety standard for information technology equipment, aims to ensure the electrical, mechanical, thermal and fire safety of the equipment to ensure the personal safety and property safety of users.
