Interpretation

  1 A Type Approval Certificate showing compliance with the PSPC 5 should be issued if the results of either method A+D, or B+D, or C+D are found satisfactory by the Administration.

  2 The Type Approval Certificate should indicate the product and the shop primer tested. The certificate should also indicate other type approved shop primers with which the product may be used which have undergone the crossover test in a laboratory meeting the requirements in Method A, 1.1 of this UI.

  3 The documents required to be submitted are identified in the following sections, in addition for all type approvals the following documentation is required: Technical Data Sheet showing all the information required by PSPC 3.4.2.2.

  4 Winter type epoxy requires separate prequalification tests, including a shop primer compatibility test according to PSPC Annex 1. Winter and summer type coating are considered different unless Infrared (IR) identification and Specific Gravity (SG) demonstrate that they are the same.

  1 A coating pre-qualification test should be carried out by a test laboratory recognized by the Administration and the test laboratory should meet the requirements set out in IACS UR Z17.

  2 Results from satisfactory pre-qualification tests (PSPC Table 1: 1.3) of the coating system should be documented and submitted to the Administration.

  3 Type Approval tests should be carried out for the epoxy-based system with the stated shop primer in accordance with the PSPC Annex 1. If the tests are satisfactory, a Type Approval Certificate should be issued to include both the epoxy and the shop primer. The Type Approval Certificate will allow the use of the epoxy either with the named shop primer or on bare prepared steel.

  4 An epoxy-based system may be used with shop primers other than the one with which it was originally tested provided that the other shop primers are approved as part of a system (PSPC Table 1: 2.3 and Table 1: 3.2) and have been tested according to PSPC Annex 1, Appendix 1, 1.7, which is known as the "crossover test". If the test or tests are satisfactory, a Type Approval Certificate should be issued. In this instance, the Type Approval Certificate should include the details of the epoxy and a list of all shop primers with which it has been tested that have passed these requirements. The Type Approval Certificate will allow the use of the epoxy with all the named shop primers or on bare prepared steel.

  5 Alternatively, the epoxy can be tested without shop primer on bare prepared steel to the requirements of the PSPC, Annex 1. If the test or tests are satisfactory, a Type Approval Certificate should be issued. The Type Approval Certificate should just record the epoxy. The certificate will allow the use of the epoxy on bare prepared steel only. If, in addition, crossover tests are satisfactorily carried out with shop primers which are approved as part of a system, the Type Approval Certificate should include the details of shop primers which have satisfactorily passed the crossover test. In this instance, the Type Approval Certificate will allow the use of the epoxy-based system with all the named shop primers or on bare prepared steel.

  6 The Type Approval Certificate is invalid if the formulation of either the epoxy or the shop primer is changed. It is the responsibility of the coating manufacturer to inform the Administration immediately of any changes to the formulation.

  1 Coating manufacturer's records, which shall at least include the information indicated in 2, should be examined to confirm that the coating system had 5 years' field exposure and that the current product is the same as that being assessed.

  2 Manufacturer's records

• original application records;
• original coating specification;
• original technical data sheet;
• current formulation's unique identification (code or number);
• if the mixing ratio of base and curing agent has changed, a statement from the coating manufacturer confirming that the composition mixed product is the same as the original composition. This should be accompanied by an explanation of the modifications made;
• current technical data sheet for the current production site;
• SG and IR identification of original product;
• SG and IR identification of the current product; and
• if original SG and IR cannot be provided, then a statement from the coating manufacturer confirming the readings for the current product are the same as those of the original.

  3 Either class survey records from an Administration or a joint (coating manufacturer and Administration) survey of all ballast tanks of a selected vessel should be carried out for the purpose of verification of compliance with the requirements of 1 and 7. The reporting of the coating condition in both cases should be in accordance with the IACS Recommendation 87, section 2.

  4 The selected vessel should have ballast tanks in regular use, of which:

• at least one tank is approximately 2,000 m³ or more in capacity;
• at least one tank shall be adjacent to a heated tank; and
• at least one tank contains an underdeck exposed to the sun.

  5 In the case that the selected vessel does not meet the requirements in 4, then the limitations should be clearly stated on the Type Approval Certificate. For example, the coating cannot be used in tanks adjacent to heated tanks or underdeck or tanks with a volume greater than the size surveyed.

  6 In all cases of approval by Method B, the shop primer should be removed prior to application of the approved epoxy-based system coating, unless it can be confirmed that the shop primer applied during construction is identical in formulation to that applied in the selected vessel used as a basis for the approval.

  7 All ballast tanks should be in "GOOD" condition excluding mechanical damages, without touch up or repair in the prior 5 years.

  8 "Good" is defined as: Condition with spot rusting on less than 3% of the area under consideration without visible failure of the coating. Rusting at edges or welds, must be on less than 20% of edges or welds in the area under consideration.

  9 Examples of how to report coating conditions with respect to areas under consideration should be as those given in IACS Recommendation 87.

  10 If the applied NDFT is greater than required by the PSPC, the applied NDFT will be the minimum to be applied during construction. This should be reported prominently on the Type Approval Certificate.

  11 If the results of the inspection are satisfactory, a Type Approval Certificate should be issued to include both the epoxy-based system and the shop primer. The Type Approval Certificate shall allow the use of the epoxy-based system either with the named shop primer or on bare prepared steel. The Type Approval Certificate should reference the inspection report which should also form part of the Coating Technical File.

  12 The Type Approval Certificate is invalid if the formulation of either the epoxy-based system or the shop primer is changed. It is the responsibility of the coating manufacturer to inform the Administration immediately of any changes to the formulation.

  1 Epoxy-based system coatings systems with existing satisfactory Marintek test reports minimum level B1 including relevant IR identification and SG, issued before 8 December 2006 can be accepted. If original SG and IR documentation cannot be provided, then a statement should be provided by the coating manufacturer, confirming that the readings for the current product are the same as those of the original.

  2 The Marintek test report with IR and SG information should be reviewed and, if satisfactory, a Type Approval Certificate should be issued. The certificate should record the report reference and the shop primer used. The Type Approval Certificate should allow the use of the epoxy-based system either with the named shop primer, unless there is evidence to indicate that it is unsuitable, or on bare prepared steel.

  3 The epoxy-based system approved by this method may be used with other shop primers if satisfactory crossover tests are carried out with shop primers which are approved as part of a system, see Method A, 4. In this instance, the Type Approval Certificate should include the details of the epoxy-based system and a list of all shop primers which have passed these requirements. The Type Approval Certificate will allow the use of the epoxy-based system with all the named shop primers or on bare prepared steel.

  4 Such coatings should be applied in accordance with PSPC Table 1 rather than the application conditions used during the approval test which may differ from the PSPC, unless these are more stringent than PSPC Annex 1, for example if the NDFT is higher or high pressure water washing and or sweep blasting of the shop primer is used. In such cases these limiting conditions should be added to the Type Approval Certificate and should be followed during coating application in the shipyard.

  5 The Type Approval Certificate is invalid if the formulation of either the epoxy-based system or the shop primer is changed. It is the responsibility of the coating manufacturer to inform the Administration immediately of any changes to the formulation.

  1 The coating/shop primer manufacturer should meet the requirements set out in IACS UR Z17, paragraphs 4, 5, 6 and 7 (except for 4.6) and paragraphs 2 to 7 below, which should be verified by the Administration.

  2 Coating manufacturers

• .1 Extent of engagement – Production of coating systems in accordance with PSPC and this UI.

• .2 These requirements apply to both the main coating manufacturer and the shop primer manufacturer where both coatings form part of the total system.

• .3 The coating manufacturer should provide to the Administration the following information:

  • A detailed list of the production facilities.
  • Names and location of raw material suppliers will be clearly stated.
  • A detailed list of the test standards and equipment to be used, (Scope of approval).
  • Details of quality control procedures employed.
  • Details of any sub-contracting agreements.
  • List of quality manuals, test procedures and instructions, records, etc.
  • Copy of any relevant certificates with their issue number and/or date, e.g., Quality Management System certification.

• .4 Inspection and audit of the manufacturer's facilities should be based on the requirements of the PSPC.

• .5 With the exception of early "scale up" from laboratory to full production, adjustment outside the limitations listed in the QC instruction referred to below is not acceptable, unless justified by trials during the coating system's development programme, or subsequent testing. Any such adjustments must be agreed by the formulating technical centre.

• .6 If formulation adjustment is envisaged during the production process, the maximum allowable limits should be approved by the formulating technical centre and clearly stated in the QC working procedures.

• .7 The manufacturer's quality control system should ensure that all current production is the same formulation as that supplied for the Type Approval Certificate. Formulation change should not be permissible without testing in accordance with the test procedures in the PSPC and the issue of a Type Approval Certificate by the Administration.

• .8 Batch records including all QC test results such as viscosity, specific gravity and airless spray characteristics should be accurately recorded. Details of any additions should also be included.

• .9 Whenever possible, raw material supply and lot details for each coating batch should be traceable. Exceptions may be where bulk supply such as solvents and pre-dissolved solid epoxies are stored in tanks, in which case it may only be possible to record the supplier's blend.

• .10 Dates, batch numbers and quantities supplied to each coating contract should be clearly recorded.

  3 All raw material supply should be accompanied by the supplier's "Certificate of Conformance". The certificate should include all requirements listed in the coating manufacturer's QC system.

  4 In the absence of a raw material supplier's certificate of conformance, the coating manufacturer should verify conformance to all requirements listed in the coating manufacturer's QC system.

  5 Drums should be clearly marked with the details as described on the Type Approval Certificate.

  6 Product Technical Data Sheets should comply with all the PSPC requirements. The QC system will ensure that all Product Technical Data Sheets are current.

  7 QC procedures of the originating technical centre should verify that all production units comply with the above stipulations and that all raw material supply is approved by the technical centre.

  8 In the case that a coating manufacturer wishes to have products which are manufactured in different locations under the same name, then IR identification and SG should be used to demonstrate that they are the same coating, or individual approval tests will be required for the paint manufactured in each location.

  9 The Type Approval Certificate is invalid if the formulation of either the epoxy-based system or the shop primer is changed. It is the responsibility of the coating manufacturer to inform class immediately of any changes to the formulation. Failure to inform class of an alteration to the formulation should lead to cancellation of the certificates for that manufacturer's products
