适用范围：This part of ISO 15181 specifies the apparatus and analytical method for determining the amount oftolylfluanid and dichlofluanid that has been released from an antifouling paint into artificial seawater inaccordance with the procedure given in ISO 15181-1.Tolytfluanid and dichlofluanid are unstable in the marine environment and degrade to formdimethyltolylsulfamide (DMST) and dimethylphenylsulfamide (DMSA), respectively. This part of ISO 15181specifies a method for converting the released species into these degradation products, quantifying theirconcentration in the treated artificial seawater samples, and gives the final calculation for the release rate oftolylfluanid and dichlofluanid under the specified laboratory conditions.This part of ISO 15181 is designed to allow the concurrent determination of tolylfluanid, dichlofluanid andother biocides that can be released by a given antifouling paint (for example, copper) through the analysis ofseparate 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 methodare from 1,3 μg.cm
