19、O 22775:2004 (E) 4 1 Scope This document specifies two methods for determining the propensity of a metal surface to either change visually due to contamination by atmospheric pollution (Method 1: sulphide tarnishing), or to corrode due to the action of salt water (Method 2: salt water corrosion). 2
20、Terms and definitions For the purposes of this document, the following term and definition applies. corrosion resistance propensity of a metal surface either not to change visually due to chemical attack by atmospheric pollution, or not to be altered due to the action of salt water 3 Principle 3.1 M
21、ethod 1 A test specimen is stored in a moist atmosphere containing a low concentration of hydrogen sulphide gas for 1 h. The specimen is then assessed subjectively for signs of discoloration. 3.2 Method 2 Cotton lawn, saturated with sodium chloride solution, is wrapped around a test specimen. This a
22、ssembly is then stored in a sealed bag for 24 h at room temperature. The test specimen is then subjectively assessed for signs of corrosion and the lawn assessed for staining. 4 Apparatus, materials and reagents 4.1 Method 1 4.1.1 Kipps generator or other hydrogen sulphide source. WARNING This equip
23、ment should be used only by qualified personnel owing to the extremely toxicity of hydrogen sulphide. 4.1.2 Fume cupboard 4.1.3 Glass vessel which can be sealed and is of sufficient dimensions to contain the test specimen. 4.1.4 Glass tube with volume approximately equal to one thousandth of the vol
