Introduction to ISO 13849-1 Safety Standard

The ISO 13849-1 safety standard from the International Organization for Standardization (ISO) is a universal standard meant to help build safety systems in machinery with sufficient reliability. For machine builders and users, ISO 13849-1 is a guide for safe operations.

This safety standard replaced the older EN 954-1 standard and has made many improvements, although the categories used for defining system structure are the same. For safe operation of machinery, there are a few things you should know about ISO 13849-1, starting with “Part 1: General Principles for Design.”

What Does ISO 13849-1 Apply to?

ISO defines the first part of ISO 13849-1 as follows:

“ISO 13849-1:2015 provides safety requirements and guidance on the principles for the design and integration of safety-related parts of control systems (SRP/CS), including the design of software. For these parts of SRP/CS, it specifies characteristics that include the performance level required for carrying out safety functions. It applies to SRP/CS for high demand and continuous mode, regardless of the type of technology and energy used (electrical, hydraulic, pneumatic, mechanical, etc.), for all kinds of machinery.”

Essentially, ISO 13849-1 uses a statistical analysis to determine the probability of failure and danger over time of components and circuitry to find a performance level (PL). The PL can then be used in risk assessments to ensure the proper safety devices have been implemented.

Why is ISO 13849-1 Important?

ISO 13849-1 is important because designing safety features into machinery is one of the best ways to ensure safety over the lifetime of equipment. It is a proactive measure for maintaining a safe work environment.

Manufacturers and integrators both have a major responsibility when it comes to operational safety. A safe environment protects workers, machinery and bottom lines alike – a worthy investment for anyone in the industrial sector.

Safety has never been more important in today’s factory setting. The robotics industry has a remarkable safety track record, but robots still present unique dangers to workers. With industrial robots expanding across the globe, safety standards have helped keep the workplace safe.
