safetyrated

Safetyrated is a term used in safety engineering and industrial automation to indicate that a device, component, or system has been evaluated and certified as meeting predefined safety requirements for use in safety-related applications. It is not a universal standard in itself; the rating reflects compliance with relevant safety standards and the level of risk reduction claimed for the product. Common frameworks cited with safetyrating include IEC 61508 for functional safety, ISO 13849-1 for safety-related parts of control systems (using Performance Levels, PL), IEC 62061 for machinery safety, and ISO 26262 for automotive safety. Industry contexts such as rail and process industries may also rely on EN 50126/50128/50129 or other sector-specific norms.

Determination of a safetyrating begins with hazard analysis and risk assessment to determine the required safety integrity. Designers define a safety concept with architecture, redundancy, diagnostics, and safe-state behavior. The product undergoes testing and documentation to demonstrate achievement of the target level (for example PL, SIL, or ASIL equivalents) and, in many cases, third-party assessment or certification by a notified body.

Use and interpretation: Safetyrated equipment is intended for safety-critical functions such as emergency stops, interlocks, safety relays, or protective sensors. The rating should be supported by a safety case or technical file detailing the scope, the declared level, and any limitations. The term alone does not guarantee suitability for all safety tasks; users must ensure the declared level matches the application's risk, environment, and lifecycle requirements.

Limitations: Marketing usage may vary; always verify the standards referenced, the declared safety level, and the conditions of use. Refer to the product’s safety manual and certification documents for precise interpretation.
