Scope: These technical conditions serve as the technical rules for measuring the volume of the main ballast water tanks, side tanks and tanks inside the pressure-resistant hull of the new ship during the construction stage, as well as the delineation of the depth gauge and water column. Mainly suitable for first-production boats trial-produced by various shipyards. For the same type of submarines built in batches by the same shipyard, the trim balance water tank, adjust the water tank, and test the first three boats. If the measurement results are all within the allowable error range, starting from the fourth boat, the tank can no longer be measured, and the tank can be copied and marked according to the sample rod of the first boat. The full volume measurement of the main ballast water tank is only measured on the first boat produced by each factory. However, for tanks with one of the following conditions, measurements must be continued on subsequent boats.
