What is BS EN 151542:2013+A1:2015?

In the field of technology and engineering, standards play a crucial role in ensuring the quality, safety, and compatibility of products and services. One such important standard is BS EN 151542:2013+A1:2015. This article aims to provide a thorough understanding of this standard and its significance in various industries.

The Purpose of BS EN 151542:2013+A1:2015

BS EN 151542:2013+A1:2015 is a technical standard that focuses on the design, development, and implementation of safety-related control systems for machinery. It sets out requirements and guidelines for achieving functional safety to prevent or reduce risks associated with machinery operation. The standard emphasizes the importance of systematic management throughout the lifecycle of the machinery and promotes the use of well-established safety principles and practices.

Key Elements and Requirements

The standard covers various aspects related to safety-related control systems, including risk assessment, safety functions, architecture, design, validation, and verification. It requires the identification and evaluation of potential hazards associated with machinery and the determination of necessary safety functions to mitigate those risks. BS EN 151542:2013+A1:2015 also specifies criteria for the design and implementation of safety measures, such as redundancy, monitoring, and diagnostic capabilities.

Implementation and Compliance

To comply with BS EN 151542:2013+A1:2015, manufacturers and system integrators need to follow a systematic and documented approach. This involves conducting thorough risk assessments, designing and implementing appropriate safety measures, documenting all relevant information, and performing validation and verification activities. Compliance with the standard ensures that machinery meets the required safety levels, reduces the likelihood of accidents or injuries, and provides a basis for legal and regulatory compliance.


BS EN 151542:2013+A1:2015 is an essential technical standard that contributes to ensuring the safety and reliability of machinery and equipment. By providing guidelines and requirements for safety-related control systems, the standard helps organizations in various industries to minimize risks and protect both workers and end-users. Understanding and implementing this standard not only enhances the overall safety culture but also improves the quality and integrity of products and services. Therefore, it is crucial for all relevant stakeholders to be aware of and comply with BS EN 151542:2013+A1:2015 in their respective fields.
