ASNT (American Society for Non-Destructive Testing) examinations are held at the Rotherham training centre and on-site.
Examination content is determined by an employer's written practice, i.e. employees who do not have a written practice cannot have their NDT personnel certificated under the ASNT scheme.
All companies who wish their NDT operators to be qualified to ASNT requirements must hold a written practice in accordance with the ASNT document SNT-TC-1A-Recommended Practice; this document is intended as a guideline for employers to establish their own written practice for the qualification and certification of their non-destructive testing personnel.
Written practices are available via our Level III Services Manager.
A self-employed individual may hold his own written practice, but it should be appreciated that he may be re-examined in accordance with a different written practice when employed by another organisation.
A written practice is not a set of NDT procedures. A written practice is for the control and administration of NDT personnel and is written specifically for a company's needs, e.g. related to welds only, for welds and castings, for forgings only etc.
The document may also relate to specific British Standards, American Standards,in-house procedures etc., and may cover one NDT method or say four or five.
A written practice typically consists of 10-25 pages and includes the following: Minimum training and experience requirements for personnel wishing to be certificated.
- The methods which may be relevant, e.g. UT, MT, PT, RT, ET.
- The syllbus for the training related to each method.
- The number of examination questions and number of practical test points. Theoretical questions are usually of the multi-choice type.
- Minimum examination pass marks.
Examinations duration is typically less than a day and is divided into three parts:
Typically 30-40 multi-choice questions related to the relevant NDT method.
Typically 15-20 questions related to the test equipment used, product/process and specifications/procedures used by the employer.
Typically 10 check points which may relate to one or more test sample.
Examination results are normally available within 2 working days of the examination; the employer receives details of the examination results and certificates of achievement for successful candidates, normally within 7 working days.
ASNT certificates are normally valid for 3 years.
