Lifecycle Services Industry Sector

exida’s Lifecycle Services support many different industries. Though the approaches to functional safety, cybersecurity and alarm management may be different per industry, the overall concepts remain consistent. The IEC 61508 functional safety standard for example applies to all industries and allows development of industry specific standards. As a result, we see IEC 61511 for the process industry, IEC 62061 for the machinery and discrete manufacturing industry, IEC 61513 for the nuclear industry, ISO 26262 for the automotive industry and many more.

As active members of many of these industry sector specific standard committees, exida has been on the forefront of implementing the standards in a variety of industries. With expert consultants in areas ranging from semiconductors and autonomous driving to industrial burner management systems, exida is active in all these industries providing in house and on project support.
