ISO 55259:2018, also known as "Safety requirements for machinery – Safety-related parts of control systems," is an international standard developed by the International Organization for Standardization (ISO). This standard provides guidelines and requirements for the design and implementation of safety-related parts of control systems in machinery. It aims to ensure that control systems effectively reduce or eliminate risks related to machinery operation.
Key Principles of ISO 55259:2018
ISO 55259:2018 establishes several key principles that should be followed when designing and implementing safety-related parts of control systems. These principles include:
Risk assessment: Before designing control systems, a thorough risk assessment must be conducted to identify potential hazards and determine the necessary safety measures.
Safety functions: Safety-related parts of control systems must perform specific safety functions, such as emergency stop or protective guarding, to minimize risks.
Performance levels: ISO 55259:2018 introduces Performance Levels (PL) to evaluate the effectiveness of safety-related parts. The PL indicates the probability of a safety function performing correctly under specified conditions.
Validation and verification: Control systems must be validated and verified to ensure they meet the required safety functions and performance levels. This involves testing, documentation, and evaluation processes.Benefits of Implementing ISO 55259:2018
Adopting ISO 55259:2018 can bring several benefits to organizations involved in machinery design and manufacturing:
Enhanced safety: The implementation of this standard helps to improve the overall safety of machinery, reducing the risk of accidents and injuries.
Legal compliance: ISO 55259:2018 provides a framework that ensures compliance with relevant safety regulations and legal requirements in different countries.
Market acceptance: Adhering to international safety standards enhances an organization's reputation and increases market acceptance for its products.
Risk reduction: By evaluating and mitigating risks associated with machinery, organizations can avoid costly lawsuits, recalls, and damage to their brand image.Conclusion
ISO 55259:2018 plays a crucial role in ensuring the safety of machinery by providing guidelines and requirements for the design and implementation of safety-related parts of control systems. By following this international standard, organizations can enhance safety, comply with legal requirements, improve market acceptance, and reduce risks associated with machinery operation. It is important for organizations involved in machinery design and manufacturing to familiarize themselves with ISO 55259:2018 and prioritize the implementation of its principles.
