The followings are major revised parts from the No. TEC-1289. The requirement for carriage of immersion suits for use during drills is NOT amended. This ClassNK Technical Information supersedes ClassNK Technical Information No. TEC-1289.

- For immersion suit and anti-exposure suit, air pressure test is to be conducted at three years intervals, and annually for suits over ten years of age according to MSC/Circ.1114.
Air pressure test for suits over ten years of age is required from the next periodical survey of the Cargo Ship Safety Equipment Certificate, on or after 1 June 2023.
