ISO 14118:2017 PDF Download

ISO 14118:2017 is a standard that specifies the requirements for designed-in means to prevent unexpected start-ups of machinery. Its primary purpose is to ensure the safety of human interventions in danger zones. The standard applies to all types of energy sources that can cause unexpected start-ups, such as power supply, stored energy, and external influences.

It is important to note that ISO 14118:2017 does not provide specific performance levels or safety integrity levels for safety-related control systems. Instead, it identifies available means to prevent unexpected start-ups without specifying the means for specific machines. The standard also highlights that a type-C standard may define the required means for preventing harm from unexpected start-ups, or the specific requirements for a particular machine need to be determined through risk assessment outside the scope of this document.
