1 Scope

This part of GB/T 32065 specifies the test requirements, test process and related information for salt spray test of marine instruments and components. This part is applicable to assess the salt spray corrosion resistance of marine instruments and components and the influence of salt spray on the performance and functions of marine instruments and components.

3 Test requirements

3.1 General requirements The standard atmospheric conditions in this section shall be carried out in accordance with the provisions of 4.2 in GB/T 32065.1-2015. 3.2 Test equipment 3.2.1 The test equipment should comply with the provisions in Chapter 5 of GB/T 32065.1-2015. 3.2.2 The test equipment should be a combination of salt spray test chamber (chamber), damp heat test chamber (chamber) or composite salt spray test that meets the test requirements Box (chamber), and drying box. 3.2.3 The damp heat test chamber (chamber) should meet the requirements of 3.2 in GB/T 32065.6-2015. 3.2.4 The composite salt spray test chamber (chamber) shall meet the requirements of 3.2 in GB/T 32065.6-2015 when performing damp heat test. 3.2.5 The drying box should be able to provide a dry environment of (40±2)℃. 3.3 Test conditions 3.3.1 Salt solution This experiment uses sodium chloride (chemically pure and above) and distilled water to prepare a salt solution with a concentration of 4.9% to 5.1% (mass fraction). The salt The pH of the solution at 35°C should be between 6.5 and 7.2.It can be measured with a pH meter or precision pH test paper. The pH of the salt solution can be used It can be adjusted with dilute hydrochloric acid or sodium hydroxide above the purity level. 3.3.2 Test temperature and test humidity The test temperature in the spray phase is (35±2)℃; the test temperature in the humid and hot phase is (40±2)℃, and the relative humidity is (93±3)%. 3.3.3 Settlement rate Adjust the sedimentation rate of the salt spray so that the collector can be placed at any position in the effective space of the salt spray test box (chamber) or composite salt spray test box (chamber). ......
