17.3.6.7 Each water sample should be tested on site for pH as soon as practical after sampling. Temperature changes, oxidation as a result of entrained air during sampling, and release of entrained gases due to the pressure change may result in changes in pH.
Note: See Appendix A.4.5 for significance of on-site pH testing.
17.3.6.7.1 Sampling personnel should be trained in pH determinations. The manufacturer’s instructions regarding use of testing equipment (medium) must be carefully followed for optimum test results.
17.3.6.7.2 The on-site pH result should be recorded on the sample identification tag immediately after testing.
17.3.6.8 The procedure for the distribution of samples is as follows.
17.3.6.8.1 After completion of on-site testing (17.3.6.7), appropriate seals (17.3.4.4) should be installed.
17.3.6.8.2 One set of samples should be retained at the point of origin for a minimum of 90 days from date of sampling or as agreed by requesting parties.
17.3.6.8.3 One set of samples will be delivered for independent testing as soon as possible after sampling.
17.3.6.8.4 A sample receipt must be completed and signed by each party receiving a sample. See the example of a Chain of Custody Record in Figure 2.
17.3.6.9 In addition to requirements outlined in 17.3.6.6, a report or letter summarizing the events of thç voyage must accompany the samples. Minimum requirements for the report or letter are as follows:
a. The loading and discharge ports.
b. Dates and times of each event or occurrence.
c. Ports of call and lighterings.
d. Voyage routes, including seas crossed.
e. Any significant atmospheric or meteorological disturbance during voyage, loading, or discharge such as hurncanes, typhoons, or cyclones.
f. A complete list of all samples taken accompanied by the pertinent data as the Identification labels or tags (17.3.6.6).
g. Heating records if cargo was heated.
h. Any other anomalies that could affect the cargo.
17.3.6.10 The procedure for the Report of Sampling is as follows.
17.3.6.1 0.1 A Report of Sampling will be issued to all interested parties.
17.3.6.10.2 The Report of Sampling should outline the source of each sample, date of sampling, method and equipment used, name of sampling party, seal identification, field pH test result, and distribution of samples.
17.3.6.10.3 The Report of Sampling should also specify any elements of this guideline that could not be followed.
17.3.7 Basic Analytical Procedures
17.3.7.1 Methods for performing analytical testing are referenced in API Recommended Practice 45.
17.3.7.2 Minimum tests to be performed for each sample submitted to the laboratory are listed in Table 1.
17.3.7.3 The procedure for the presentation of analytical data is as follows.
17.3.7.3.1 Results of all laboratory testing will be presented to interested parties in a report of analysis issued by the testing laboratory for each sample submitted, following instructions and format in Appendix A.2 and A.3. Any comments, including analytical anomalies, will be expressed on each report.
