Latest Developments in Fitness for Service Procedures

Webinars 15 April 2021

Structural Integrity Technical Group Meeting: Latest Developments in Fitness for Service Procedures in BS7910, R6 and ASME/API579

The application of fitness for service procedures in different industries worldwide is heavily dominated by three key codes and standards: BS7910, R6, and ASME/ API579. By a rare coincidence all three of these important documents have either been revised recently or are in the process of being revised in the very near future. Experts with detailed knowledge of the developments in each document will make presentations to help highlight the most significant changes. The speakers are highly experienced engineers who chair a committee or are members of one or more of the committees overlooking the developments in these codes.
