What is EN ISO 13949-4:2019?

EN ISO 13949-4:2019 is an International Standard that specifies the safety-related parts of control systems (SRP/CS) for machinery. It is part of a series of standards developed by the International Organization for Standardization (ISO) and the European Committee for Standardization (CEN), aimed at ensuring the safety of machinery and equipment.

Understanding Safety-Related Parts of Control Systems

In order to understand EN ISO 13949-4:2019, it is important to grasp the concept of safety-related parts of control systems. These are components within a control system that contribute to the overall safety performance of machinery. They include electrical, electronic, and programmable electronic systems (E/E/PE) specifically designed to carry out safety functions.

Safety-related parts of control systems are crucial in ensuring the safe operation of machinery, particularly when it comes to high-risk applications. Without proper safety measures, there could be potential hazards such as unintended machine movements, collisions, or human errors resulting in accidents.

The Importance of EN ISO 13949-4:2019

EN ISO 13949-4:2019 provides guidelines for designing safety-related parts of control systems. It helps manufacturers identify potential risks, assess safety requirements, and implement appropriate measures to mitigate those risks. This standard emphasizes the use of safety principles such as redundancy, diversity, and fault-detection to increase the reliability of safety-related parts.

By adhering to EN ISO 13949-4:2019, manufacturers can ensure that their machinery meets international safety standards, reducing the likelihood of accidents and improving overall operational safety. Compliance with this standard also enhances product quality and longevity by identifying and addressing safety concerns during the design and manufacturing stages.

Implementing EN ISO 13949-4:2019 in Practice

Integrating EN ISO 13949-4:2019 requirements into the design and development processes of machinery requires careful planning and expertise. Manufacturers need to analyze the safety functions necessary for their machinery, identify performance levels required for each function, and implement suitable safety measures accordingly.

Additionally, thorough risk assessments should be conducted to identify potential hazards, estimate the severity of risks, and determine the necessary safety measures. This includes considering factors such as control reliability, diagnostic coverage, and parameters associated with the safety-related parts of control systems.

Regular inspections, testing, and maintenance of safety-related parts are essential to ensure ongoing compliance with EN ISO 13949-4:2019. It is important to remember that this standard serves as a fundamental tool for optimizing machine safety, and its implementation should be an ongoing process involving all relevant stakeholders.
