Types of tank inspection4.1
Inspection for type approval4.1.1
GeneralThe inspection for type approval shall be carried out on a single tank for an individual approval or approval of a rangeof tanks.A type approval which includes a range of tanks will allow the following variations to the design without requiring a newapproval, if there are no other conflicting technical or legal requirements:– a decrease in the initial design temperature range;SIST EN 12972:2002
Page 6EN 12972:2001– a decrease in the maximum gross mass;– a reduction in volume only resulting from variations in diameter (not applicable to non-cylindrical tanks) and length;the approval file includes a calculation for each proposed diameter, length and number of compartments of the tankunder the most unfavourable conditions, i.e.:× greatest density of goods,× greatest tank length and diameter,. greatest tank front compartment,. greatest tank rear compartment;– a variation in the grade of the material used; in the case of austenitic steels and aluminium alloys different gradesmay be allowed with the following reserves:. use of the same qualified welding procedure;. calculation is carried out in the most unfavourable case, in particular the mechanical characteristics selected arefor each element the lowest values of the grades used;. the instruction manual specifies the alternatives for the compatibility with the substances being transported;– movement or modification of nozzles and manholes provided that the same level of protection is afforded and thetank strength calculation takes into account the most unfavourable case;– an increase of the number of baffles and surge plates;– an increase of the wall thickness provided the same welding procedures are used;– a decrease of the maximum (allowable) working pressure (not valid for portable tanks subject to the IMDG Code);– an increase in the thickness of the insulation used for additional protection;– an increase in the effectiveness of the thermal insulation of the tank;– use of alternative service equipment if there is no change in the technical specification of the equipment and it isplaced in the same location.4.1.2Content of inspectionThe inspection for type approval shall be carried out in accordance with the following clauses: – examination of documents (see 5.2.);– verification of the tank against the design (see 5.3);– inspection of the tank interior (see 5.4);– inspection of the tank exterior (see 5.5);– hydraulic pressure test (see 5.6);– vacuum test (see 5.7, for tanks which fall within the scope of directive 94/63 EC);– leakproofness test (see 5.8);– determination of water capacity (see 5.9);– inspection of service equipment (see 5.10);– inspection of frame or other structural equipment of portable tanks (see 5.11).SIST EN 12972:2002
Page 7EN 12972:20014.1.3
DocumentationThe results of the inspection for type approval shall be recorded by the inspector in a test report.A preliminary report may be issued after examination of the documents.In addition to the test report it is recommended that the inspector submits a data sheet to assist the issuing of typeapproval. It is recommended that this data sheet form an annex to the type approval certificate.4.2
Initial inspection4.2.1
Content of inspectionThe initial inspection shall be carried out in accordance with the following clauses:– examination of documents (see 5.2.2);– verification of the tank against the design (see 5.3);– inspection of the tank interior (see 5.4);– inspection of the tank exterior (see 5.5);– hydraulic pressure test (see 5.6);– leakproofness test (see 5.8);– determination of water capacity (see 5.9);– inspection of service equipment (see 5.10);– inspection of frame or other structural equipment of portable tanks (see 5.11).4.2.2
Documentation, certification and markingThe results of the initial inspection shall be recorded by the inspector in a certificate. This certificate shall mention anysignificant defect found and the related repairs carried out. It is acceptable for the certificate of initial inspection of atank which has been tested for type approval to be completed using the results of the inspection for type approval. Forcertification and marking 5.12 shall be applied.SIST EN 12972:2002

Periodic inspection4.3.1
Content of inspectionThe periodic inspection shall be carried out in accordance with the following clauses:– examination of documents (see 5.2.3);– inspection of the tank interior (see 5.4);– inspection of the tank exterior (see 5.5);– hydraulic pressure test (see 5.6);– leakproofness test (see 5.8);– inspection of service equipment (see 5.10);– inspection of frame or other structural equipment of portable tanks (see 5.11).For vacuum insulated tanks the inspection of the tank interior and the hydraulic pressure test are not required providedthat a satisfactory vacuum is confirmed by measurement. 4.3.2
Documentation, certification and markingThe results of the periodic inspection shall be recorded by the inspector in a certificate. This certificate shall mentionany significant defect found and the related repairs carried out. For certification and marking 5.12 shall be applied.4
