The mission of D1 is described as following:

To facilitate and promote the progress of engineering and the international exchange of in-formation and knowledge in the field of materials and emerging test techniques. To add value to this information and knowledge by means of synthesizing state-of-the-art practices and developing recommendations.

The activities of CIGRE Study Committee D1 concern the monitoring and evaluation of:
 

• new and existing materials for electrotechnology,
• diagnostic techniques and related knowledge rules,
• emerging test techniques which may be expected to have a significant impact on power systems in the medium to long term.
• support of other study committees in their analysis of recently introduced and develop-ing materials, emerging test techniques and diagnosis techniques
