What is IEC 62471 Ed.2:2018 ?

IEC 62471 Ed.2:2018 is a crucial standard for evaluating the mechanical strength of electrical and electronic equipment. It provides manufacturers with a standardized testing procedure to assess the equipment's ability to withstand external mechanical shocks.

IEC 62128-1 Ed.2 2018 is a technical standard developed by the International Electrotechnical Commission (IEC) that focuses on railway control and protection systems. The standard provides guidelines for the design, installation, and operation of these systems, ensuring their safety and reliability in railway applications.

One of the key features of IEC 62128-1 Ed.2 2018 is its ability to establish a common framework for the implementation of railway control and protection systems. By defining technical requirements and providing guidance, this standard aims to enhance interoperability between different systems and ensure a high level of safety and performance across the railway industry.

The standard outlines a systematic approach to conduct tests, assess performance, and classify devices based on their level of protection. This helps manufacturers ensure that their products can endure the harshest environmental conditions and maintain functionality.

The testing procedure under IEC 62471 Ed.2:2018 is designed to evaluate the mechanical strength of electrical and electronic equipment. The standard provides a set of tests to assess the equipment's ability to withstand external mechanical shocks, such as the use of a vibration table or a free-fall test.

The equipment is subjected to a series of tests, including a 1.5-second free fall test, a 15-second impact test, and a 1,000-V AC voltage test. These tests are designed to simulate the effects of external mechanical shocks on the equipment, providing a measure of its resistance to damage.

The impact test is a crucial aspect of IEC 62471 Ed.2:201It is designed to assess the equipment's ability to withstand a 1-meter drop, with a 100-percent failure mode, onto a concrete surface. The equipment is dropped from a height of 1.5 meters, and any damage observed is recorded.

ConclusionThe purpose of IEC 62471 Ed.2:2018 is to establish a common framework for the implementation of railway control and protection systems. By providing guidelines for the design, installation, and operation of these systems, the standard aims to enhance interoperability between different systems and ensure a high level of safety and performance across the railway industry.

The testing procedure outlined in IEC 62471 Ed.2:2018 is designed to evaluate the mechanical strength of electrical and electronic equipment. The equipment is subjected to a series of tests, including the use of a vibration table or a free-fall test, to simulate the effects of external mechanical shocks on the equipment.

The impact test, in particular, is a crucial aspect of the standard. It is designed to assess the equipment's ability to withstand a 1-meter drop, with a 100-percent failure mode, onto a concrete surface. The equipment is dropped from a height of 1.5 meters, and any damage observed is recorded.

Overall, IEC 62471 Ed.2:2018 is an essential standard for evaluating the mechanical strength of electrical and electronic equipment. It provides manufacturers with a standardized testing procedure to assess the equipment's ability to withstand external mechanical shocks and ensure a high level of safety and performance across the railway industry.
