To encourage and assist Members to provide high quality, appropriate and reliable testing services.

Permanent objectives

  1. Provide a forum for discussion of commercial issues.
  2. Provide a forum for discussion of issues affecting the testing sector of the ground industry (eg Health and Safety accreditation training
  3. Facilitate co-ordination of industry views and comments on new legislation, regulations and standards. (eg current work in CEN/TC 341)
