Functional Safety Certification

The IEC 61508 standard defines the requirements for suppliers to follow during product development to ensure that their products have a high level of resistance to random hardware and “systematic” design failures. exida is an ANSI accredited certification agency which assesses and certifies that a product has been designed and developed in accordance with the standard. exida follows a rigorous process that verifies the Safety Integrity Level (SIL) of a product’s hardware and software design, as well as its manufacturing and quality control procedures.
