IACS Guideline for Procedures of Testing Tanks and Tight Boundaries
1.
General
These test procedures are to ensure the weathertightness of structures/shipboard outfitting, the watertightness of tanks and watertight boundaries and structural adequacy of tanks. Tightness of all tanks and tight boundaries of the ships at the new construction and, when major conversions or repairs* have been made, those relevant to the major conversions/repairs should be confirmed by these test procedures prior to delivery of the ship. * Major repair means a repair affecting structural integrity.
2.
Application
2.1 All gravity tanks** and other boundaries required to be watertight or weathertight should be tested in accordance with this Guideline and proven tight and structurally adequate as follows: Gravity Tanks for their tightness and structural adequacy Watertight Boundaries Other Than Tank Boundaries for their watertightness, and Weathertight Boundaries for their weathertightness
** Gravity tank means a tank having a design working pressure not greater than 70 kPa at the top of the tank. 2.2 The testing of cargo containment systems of liquefied gas carriers should be in accordance with standards deemed appropriate by the Administration. 2.3 Testing of structures not listed in Table 1 or 2 should be specially considered.
3. 3.1
Types of Tests and Definition of Test The following two types of test are specified in this requirement:
Structural Test: A test to verify the structural adequacy of the construction of the tanks. This may be a hydrostatic test or, where the situation warrants, a hydropneumatic test. Leak Test: A test to verify the tightness of the boundary. Unless a specific test is indicated, this may be a hydrostatic/hydropneumatic test or air test. Leak test with remark
*3 in Table 1 includes hose test as an acceptable medium of the test. 3.2 Definition of each type of test is as follows: A test by filling the space with a liquid to
