What Is EN ISO 13949-6:2019?

EN ISO 13949-6:2019 is a professional technical standard that focuses on the safety of machinery and measures to prevent or control hazards associated with machinery. It provides guidelines and specifies requirements for the design, integration, and validation of safety-related parts of control systems.

The Purpose of EN ISO 13949-6:2019

The primary purpose of EN ISO 13949-6:2019 is to ensure the safety of machinery by minimizing risks and preventing accidents or injuries to personnel operating or maintaining machinery. The standard aims to achieve this by promoting the use of functional safety principles in the design and implementation of safety-related control systems.

Main Requirements and Guidelines

EN ISO 13949-6:2019 outlines several key requirements and guidelines to be followed in order to achieve compliance with the standard. These include:

Identification of Safety Functions: The standard requires the identification and classification of all safety functions within a machine to assess their potential risk.

Performance Level (PL) Determination: It defines Performance Levels based on the severity of potential injury and the probability of its occurrence.

Design and Implementation: The standard provides guidance on the design and implementation of safety-related control systems, including hardware and software requirements.

Validation: It emphasizes the importance of validating safety-related control systems to ensure they meet the required Performance Levels.

Benefits of Compliance

Compliance with EN ISO 13949-6:2019 offers several benefits, such as:

Enhanced Safety: By following the guidelines of this standard, machinery manufacturers can improve the safety of their products and reduce the risk of accidents or injuries.

Legal and Regulatory Compliance: Compliance with relevant safety standards is often a legal requirement in many countries. Adhering to EN ISO 13949-6:2019 helps ensure compliance with such regulations.

Marketability: Machinery that meets the safety standards outlined in EN ISO 13949-6:2019 is more marketable, as it instills confidence in potential customers about the product's safety and reliability.

Safe Work Environment: Compliance with this standard contributes to creating a safer working environment for personnel operating and maintaining machinery.


EN ISO 13949-6:2019 plays a crucial role in ensuring the safe design, integration, and validation of safety-related parts of control systems in machinery. Compliance with this standard not only enhances the safety of machinery but also ensures legal and regulatory compliance and increases marketability. By adhering to its guidelines, manufacturers can establish a safe working environment and mitigate risks associated with machinery operation.
