^a One day duration is at least seven hours, which can be achieved on a single day or by accumulating hours. The maximum allowable hours in any one day is 12 hours. Experience in days is achieved by dividing the total accumulated hours by 7. * RT Film to Digital : RT Film Level 2 is required.

a. One day duration is at least seven hours, which can be achieved on a single day or by accumulating hours. b. Candidate must be certified in the main method before seeking certification in the above specific NDT techniques within that method to the corresponding level. For e.g,: to be certified as Level 2 in UT –PAUT : candidate must hold a valid Level 2 certificate in UT (any sector). c. For RT, training days does not include radiation safety training. d. Certificate in the above specific technique is valid subject to the validity of certificate in the main method. For e.g. Level 2 certificate in UT –PAUT is valid only when the Level 2 certificate in UT is valid (any sector).

Note:

Direct access to level 3:

Candidates seeking direct access to Level 3 or candidates whose Level 2 certificate have expired at the time of application for Level 3, shall have to successfully clear Level 2 practical examination of that method and sector (s) before they are allowed to appear for Level 3 examination.

Vision Requirements Near vision acuity :

Prior to certification, and annually thereafter, near vision acuity shall be verified to be in accordance with the requirements of ISO 18490 or shall permit reading a minimum of Jaeger number 1 or Times Roman N4.5 or equivalent letters at not less than 30 cm with one or both eyes, either corrected or uncorrected.

Colour vision

Prior to certification, recertification or renewal, the candidate/certificate holder shall demonstrate that a colour vision test has been administered within the previous 5 calendar years.

It is required that colour vision and/or grey scale perception be sufficient for the individual to be able to distinguish and differentiate between the colours or shades of grey used in the NDT methods/techniques concerned as specified by the employer.

The colour vision test shall either confirm that the individual has acceptable colour vision without restriction or shall state any limitation(s) on colour perception.

Where any limitation in colour perception exists, the employer shall confirm whether or not this condition results in any limitation(s) to method or application specific techniques.

NOTE The Ishihara 24 plate test is an example of a suitable colour vision test.

Personnel administering vision tests

Near vision acuity testing, colour vision and/or grey scale perception verification(s) shall be administered by a licensed physician, nurse, ophthalmologist or optometrist; or by another trained professional who is approved and documented by a Level 3 personnel acting on behalf of the employer.
