The testing methods for seawater corrosion in natural environment of metallic materials for ship and offshore structures ICS 47.020.05 U05 National Standards of People's Republic of China Replacing GB/T 6384-1986 Shipping and Marine Engineering Materials in natural environment The seawater corrosion test Posted 2008-08-04 2009-02-01 implementation Administration of Quality Supervision, Inspection and Quarantine of People's Republic of China Standardization Administration of China released ForewordThis standard replaces GB/T 6384-1986 "Shipping and Marine Engineering Test methods for seawater corrosion of metallic materials in the natural environment." This standard compared with GB/T 6384-1986, mainly for the following changes. --- Added "normative references"; --- Increasing the ratio of the sample; --- Increase the splash zone hanging like height determination method; --- Modify the test time and test start time; --- Weighing Accuracy modified carbon and low alloy steel samples and the like; --- Cancel A "chemical corrosion product removal method" appendix of the original standard. Appendix A of this standard is a normative appendix. The standard proposed by China Shipbuilding Industry Corporation. This standard by the National Standardization Technical Committee of marine vessels marine materials application technology at the Technical Committee. This standard was drafted. China Shipbuilding Industry Corporation seventh twenty-five Institute. The main drafters of this standard. Hou Jian, Guo Weimin, Li Wenjun, Dengchun Long, Liu Dayang. This standard replaces the standards previously issued as follows. --- GB/T 6384-1986. Shipping and Marine Engineering Materials in natural environment The seawater corrosion test1 ScopeThis standard specifies the offshore and marine metallic material in natural environment of marine corrosion test conditions, means comparison sample test Sample preparation, procedures, and methods of evaluation of results. This standard applies to ships and marine engineering materials with metal immersion, tidal and splash seawater corrosion test under natural conditions, assessment material Material corrosion resistance.2 Normative referencesThe following documents contain provisions which, through reference in this standard and become the standard terms. For dated references, subsequent Amendments (not including errata content) or revisions do not apply to this standard, however, encourage the parties to the agreement are based on research Whether the latest versions of these documents.

When the test in two ways, the lower end of the sample from the seabed is not less than 0.8m. Note. The lowest point is the lowest place in the front 10a. 3.2.2 tidal range The average tidal range specimen placed in the tide of ± 0.3m. 3.2.3 Splash Splash test sample should be placed in the test waters hung the most serious corrosion height range. Carbon steel for the test material, by a period of not less than 1a Preparation of different heights coupon exposure tests, corrosion identify specific locations and specific facilities on the most serious height range. Note. The average is the average of the tide before 10a. ......Tips & Frequently Asked Questions:Question 1: How long will the true-PDF of GB/T 6384-2008_English be delivered?Answer: Upon your order, we will start to translate GB/T 6384-2008_English as soon as possible, and keep you informed of the progress.
