    Class 3 piping does require any NDT other than VT. Clause 7.1 (ii)

    I think it is a trick question – pneumatic testing always requires 100% NDT,

    The answer they would be after, is as follows –

    Due to being Class 3 piping, it is exempt from all NDT, apart from visual scanning & inspection.
    However, due to the need to undertake pneumatic testing, all butt welded joints shall be tested as though they are class 1 joints (list all required testing & percentages), and all other welds around openings, or with a throat thickness greater than 6mm, require surface Magnetic Particle Inspection to be undertaken.
