.4 reseal the sample and record the new reseal details on the test record.

4.4   The two subsamples shall be tested in succession, in accordance with the specified test method referred to in regulation 2.1.30 of this Annex. For the purposes of this Part 2 verification procedure, the results obtained shall be referred to as ‘2A’ and ‘2B’:

.1 results 2A and 2B shall be recorded on the test record in accordance with requirements of the test method; and

.2 if the results of 2A and 2B are within the repeatability (r)⁵ of the test method, the results shall be considered valid; or

.3 if the results of 2A and 2B are not within the repeatability (r) of the test method, both results shall be rejected and two new subsamples shall be taken by the laboratory and tested. The sample bottle shall be resealed in accordance with paragraph 4.3.4 after the new subsamples have been taken; and

.4 in the case of two failures to achieve repeatability between 2A and 2B, the cause of that failure shall be investigated by the laboratory and resolved before further testing of the sample is undertaken. On resolution of that repeatability issue, two new subsamples shall be taken in accordance with paragraph 4.3. The sample shall be resealed in accordance with paragraph 4.3.4 after the new subsamples have been taken.

4.5   If the test results of 2A and 2B are valid, an average of these two results shall be calculated. That average value shall be referred to as ‘Z’ and shall be recorded on the test record:

.1 if Z is equal to or less than the applicable limit required by regulation 14, the sulphur content of the fuel oil as represented by the tested sample shall be considered to have met the requirement;

.2 if Z is greater than the applicable limit required by regulation 14 but less than or equal to that applicable limit + 0.59R (where R is the reproducibility of the test method),⁶ the sulphur content of the fuel oil as represented by the tested sample shall be considered to have met the requirement; or

.3 if Z is greater than the applicable limit required by regulation 14 + 0.59R, the sulphur content of the fuel oil as represented by the tested sample shall be considered to have not met the requirement.

4.6   The final results obtained from this verification procedure shall be evaluated by the competent authority.

4.7   The laboratory shall provide a copy of the test record to the competent authority managing the verification procedure.

1 Samples taken in accordance with the 2009 Guidelines for the sampling of fuel oil for determination of compliance with the revised MARPOL Annex VI (resolution MEPC.182(59)).

2 Samples taken in accordance with the 2019 Guidelines for on board sampling for the verification of the sulphur content of the fuel oil used on board ships (MEPC.1/Circ.864/Rev.1).

3 Refer to the 2020 Guidelines for on board sampling of fuel oil intended to be used or carried for use on board a ship (MEPC.1/Circ.889).

4 The laboratory is to be accredited to ISO/IEC 17025:2017 or an equivalent standard for the performance of the given sulphur content test ISO 8754:2003.

5 Repeatability (r) calculation in accordance with ISO 4259:2017‑2 and as defined in the test method used.

6 Reproducibility (R) calculation in accordance with ISO 4259:2017‑2 and as defined in the test method used.

7 Results of testing undertaken by the company or other entities are outside the MARPOL process and hence should be considered within the approach given by ISO 4259:2017‑2 regarding recipient drawn samples.
