GUL Training (GULT), a division of Guided Ultrasonic Limited, operates the GUL Qualification and Certification Scheme.

The original GUL training scheme was set in the year 2000, and has been updated to its current form in 2018. The GULT Qualification and Certification Scheme has been developed to comply with ISO 17024:2012 for Personnel Certification. Furthermore, the training, qualification and certification requirements listed in the scheme document and Annexes have been written to comply with those stated in ISO 9712:2012. While there are no requirements listed within the ISO 9712:2012 for the GWT method, GUL Training, in consultation with an independent and industry-led Advisory Committee, has defined the appropriate requirements for the guided wave testing method.

The guided wave testing method can be applied to a variety of product sectors (see Annex 1 of the GULT Qualification and Certification Scheme), including (but not limited to), pipes, rails and plates. Additionally, within these product sectors, specific application sectors have been defined and combine the competency requirements for common industrial applications. The GULT certification scheme is generic to all products and application sectors of GWT using Guided Ultrasonics Ltd. (GUL) equipment. The referenced application sector specific documents indicate all of the sector specific information.
