GB/T 7789-2007Dynamic test method for performance of marine antifouling paint (English PDF)

4.1 Test conditions

4.1.1 Test place

Dynamic tests must be carried out in natural seawater. Dynamic testing device can be installed in the following locations.

a) real sea trials floating craft;

b) large natural sea pool;

c) having a flow of natural seawater sea sink.

4.1.2 Dynamic test device

4.1.2.1

Dynamic test device includes a power transmission, model A holder shown in three parts, test equipment and model holder in the Appendix.

Requirements model movement line speed (18 ± 2) kn, must be out in sea level 20cm or less, and can not be the model runs.

Real sea immersion test 4.1.2.2 Dynamic test panels anchored when carried out according to the test method GB/T 5370 may require.

4.1.3 Dynamic test opportunity

Marine fouling initial test time dynamic test should be expected based anti-fouling paints used for the test of antifouling efficiency and test sites

Growing season season to choose. Should normally be in the marine fouling organism before the growing season (1-2 months) began experimenting, making full dynamic test

Ministry cycle is still within the fouling organisms growing season.

4.2 Preparation of template

4.2.1 model materials and sizes

4.2.1.1 template substrate material

Dynamic test panel substrate using 3mm thick carbon steel plate.

4.2.1.2 template size

Dynamic test panel dimensions of 260mm × 100mm × 3mm, 4 corners of the open model has four mounting holes 7, such as

1 shown in FIG. Each antifouling dynamic test model is three.
