GB/T 24488-2009 Test method for electrochemical properties of magnesium alloys sacrificial anode

Scope

1.1 This standard specifies the test method for the electrochemical performance of magnesium alloy sacrificial anodes in a saturated calcium sulfate and magnesium hydroxide medium.
1.2 This standard is applicable to the testing of the electrochemical performance of magnesium alloy sacrificial anodes simulating their long-term exposure to an environment filled with gypsum bentonite sodium sulfate [its typical components are: gypsum (CaSO4·2H2O, 75%) + bentonite (20%) + sodium sulfate (5%)] in a saturated calcium sulfate and magnesium hydroxide electrolyte.
1.3 This standard aims to determine the electrochemical performance of magnesium alloy sacrificial anodes for quality assurance between suppliers and customers. However, the long-term performance in the field may not be equivalent to the performance characteristics obtained by this laboratory test method.
1.4 This standard does not address all safety issues related to its use. It is the responsibility of the users of this standard to take appropriate safety and health measures before use and to establish corresponding rules and regulations.
