An update to the IEC 62474 declarable substance list (DSL) and data exchange format was published on April 8, 2015. Regulatory changes prompted 5 new and modified substance entries. Nearly 30 other changes were implemented as part of a year-long DSL review to identify substances whos names have changed in regulatory usage and to implement common naming conventions.

Details of the update are provided on the IEC 62474 blog.
