Paints and varnishes - Determination of release rate of biocides from antifouling paints - Part 3: Calculation of the zinc ethylene-bis(dithiocarbamate) (zineb) release rate by determination of the concentration of ethylenethiourea in the extract (ISO 151

Scope: This part of ISO 15181 specifies the apparatus and analyticalmethod for determining the amount of zineb that has been released from an antifouling paint into artificial seawater in accordance with the procedure given in ISO 15181-1.Zineb is released from antifouling paints in the form of ionic ethylene-bis(dithiocarbamate) which is unstable in the marine environment.This part of ISO 15181 describes a method for converting the released specifies into a stable degradation product,ethylenethiourea,and determining its concentration in the treated artificial seawater samples,and gives the final calculation for the release rate of zineb under the specified labora
