What is EN ISO 11172-4:2021 ?

Title: Understanding EN ISO 11172-4:2021 and EN ISO 14142-4:2021

EN ISO 11172-4:2021 and EN ISO 14142-4:2021 are two important international standards that cater to different aspects of technology and safety. EN ISO 11172-4:2021 is a professional technical standard for coding moving pictures and audio, while EN ISO 14142-4:2021 is an international standard for the safety of machinery control systems. In this article, we will provide an overview of both standards and their purpose.

What is EN ISO 11172-4:2021?

EN ISO 11172-4:2021 is a professional technical standard that outlines the requirements for coding moving pictures and associated audio. It is part of the MPEG-1 standard, which is widely used in various digital audio and video applications. The primary purpose of EN ISO 11172-4:2021 is to provide a consistent and efficient method for compressing audio and video data without significant loss in quality. By using EN ISO 11172-4:2021, developers and manufacturers can ensure compatibility and interoperability of audio and video streams, allowing seamless integration across different platforms and devices.

What is EN ISO 14142-4:2021?

EN ISO 14142-4:2021 is an international standard that provides guidelines and specifications for the development and implementation of safety-related parts of control systems (SRP/CS) within machinery. It is part of a series of standards that aim to ensure the safety of machinery by addressing the potential risks associated with the use of these machines. The main purpose of EN ISO 14142-4:2021 is to provide manufacturers, suppliers, and users of machinery with a comprehensive framework for designing, implementing, and evaluating the safety-related parts of control systems.

By adhering to the requirements outlined in this standard, it becomes possible to minimize the risk of accidents and injuries caused by mechanical failure or malfunction. EN ISO 14142-4:2021 emphasizes the importance of proper risk assessment and risk reduction measures during the design phase of machinery and control systems. It guides manufacturers in identifying hazards associated with their machines, estimating the level of risk they present, and implementing appropriate safety measures to mitigate these risks.

Conclusion:

In conclusion, EN ISO 11172-4:2021 and EN ISO 14142-4:2021 serve different but complementary purposes in ensuring the safety and quality of machinery. By following the guidelines and requirements outlined in these standards, manufacturers, suppliers, and users can minimize the risk of accidents and injuries caused by mechanical failure or malfunction, ultimately leading to a safer and more reliable machinery.
