This part of ISO 15181 specifies the apparatus and analysis technique for determining the amount of pyridine triphenylborane (PTPB) that has been released from an antifouling paint into artificial seawater in accordance with the procedure given in ISO 15181-1. It determines the PTPB concentration in the artificial seawater extract and gives the final calculation for the release rate of PTPB. This part of ISO 15181 is designed to allow the concurrent determination of PTPB and other biocides that can be released by a given antifouling paint (for example, zineb) through the analysis of separate sub-samples of an artificial seawater extract generated in accordance with ISO 15181-1. When used in conjunction with ISO 15181-1, the practical limits for quantifying release rates by this method are from 1.8 to 500 ?g cm-2 d-1. The quantitation of release rates lower than this range will require the concentration step described in clause 7.2 NOTE or the use of an analytical method with a lower limit of quantitation for PTPB in artificial seawater than that specified in clause 3 and 5.1.
