General:
Examination requirements are documented in BGAS/ER1.
The BGAS-CSWIP approval scheme for inspectors and NDT technicians (formerly known as ERS) is primarily aimed at pipe and pipeline applications.
BGAS - British Gas Approval Scheme.
CSWIP - Certification Scheme for Welding and Inspection Personnel.
ERS - Engineering Research Station (no longer exists).
The examinations deal with the theory and practice related to the NDT or inspection method plus a knowledge of relevant British Gas Transco specifications. A good knowledge of pipeline operations is also required.
British Gas examinations are held at:

Examinations
The duration for most examinations is approximately half a day, usually commencing at 9.00 am, unless otherwise arranged.
Each examination consists of three specific parts:
(1) Question papers
Question papers usually consist of 20 to 40 questions (not multi-choice) - time limit approximately 2 hours.
(2) Practical
Typically 20 minutes to 3 hours.
(3)Interview
Up to 30 minutes.
The following questions are typical of the style found in BGAS-CSWIP examinations:
Welding inspection: Sketch a weld preparation for MMA stovepipe welding and label with typical dimensions.
Painting inspection: How is algae removed in accordance with the requirements of PAlO?
Magnetic particle inspection: What type of magnet should be used on the roots of welds in accordance with the requirements of BGES/P2?
Ultrasonic inspection: State the formula for calculating the near zone of an ultrasonic beam.
With the exception of radiographic interpretation and ultrasonic testing of welds, the practical content of the examination is conducted on a one to one basis with the examiner; this usually consists of equipment identification; demonstrating the correct use of inspection gauges likely to be used on site; identification of any
applicable consumables and assessment of both acceptable and non-acceptable samples.
The candidate may be requested to explain actions/decisions plus answer additional questions given verbally by the examiner.
The final part of the examination is an interview and is conducted on a one to one basis in an interview room. Any queries relating to the theory paper or practical examination will be discussed at this time. Additional questions may also be asked.

Examination results
There is no pass mark in percentage terms for the examination; it could be regarded as a technical interview in which an overall assessment of the candidate is made.
The results of your examination will be available within a few days; contact TWI.
If successful, the candidate will also receive an approval ticket which is valid for 5 years.
