Introduction

GB/T 41493 "Accelerated Life Test Method for Mixed Metal Oxide Anodes for Cathodic Protection" is the National Steel Standardization Technical Committee One of the standards for corrosion test methods developed by the Subcommittee on Corrosion of Metals and Alloys (the "Committee"). GB/T 41493 aims to standardize the accelerated life test method of mixed metal oxide anodes for cathodic protection, the accelerated life test results are available To compare the durability of different metal oxide anode materials and to assess whether the anode meets the design life expectancy at rated current output Require. GB/T 41493 consists of two parts. --- Part 1.Applied to concrete. The purpose is to standardize mixed metal oxide anodes for cathodic protection in concrete environments accelerated life test method. --- Part 2.Applied to soil and natural water environments. The purpose is to standardize the use of mixed materials for cathodic protection in soil and natural water environments. Accelerated life test method for alloyed metal oxide anodes. Ambiguity of understanding and any resulting responsibility arising from the dissemination or interpretation of standards by other bodies that have not been authorized in writing by the Committee The committee will not take any responsibility for any consequences. Mixed metal oxide anodes for cathodic protection Accelerated Life Test Method Part 1.Application in concrete

1 Scope

This document specifies an accelerated life test method for mixed metal oxide anodes for cathodic protection in concrete environments. accelerated life test The test results can be used to compare the durability of different metal oxide anode materials and to evaluate whether the anode meets the design pre-design at rated current output. longevity requirements. This document is also applicable to other systems of impressed current anodes embedded in concrete, which can be fixed with different any shape of the anode.

2 Normative references

The contents of the following documents constitute essential provisions of this document through normative references in the text. Among them, dated citations documents, only the version corresponding to that date applies to this document; for undated references, the latest edition (including all amendments) applies to this document.

3 Terms and Definitions

Terms and definitions defined in ISO 8044 and the following apply to this document. 3.1 mixed metal oxide anode The auxiliary anode for impressed current cathodic protection is formed by coating a mixed metal oxide conductive coating on a titanium substrate. Note. The most commonly used coating of metal oxide anodes for cathodic protection is a mixture of iridium oxide and tantalum oxide, and the specific composition of the coating can vary. 3.2 accelerated life Lifetime of mixed metal oxide anodes in accelerated tests at high current densities in the specified test medium. Note. The total test time before the failure of the mixed metal oxide anode is taken as the accelerated life. 3.3 Slot pressure celvoltage The voltage difference between the anode and cathode in a single electrolytic cell (cell). 3.4 charge density The product of the applied current density and the operating time is applied. ......
