Foreword
This standard was drafted in accordance with GB/T 1.1-2009 given rules.
This standard uses redrafted Law Amendment uses ISO 12732.2006 "Corrosion of metals and alloys bicyclic electrochemical potentiodynamic reactivation measure
Volume method. "
This standard and ISO 12732.2006 technical differences and for the following reasons.
--- On normative references, this standard has been adjusted technical differences, in order to adapt our technical conditions, the adjusted situation
The reaction conditions concentrated in Chapter 2, "Normative references", the specific adjustments are as follows.
● with the modified use ASTME112.1996 of GB/T 6394-2002 instead of ISO 643-2003 (see Chapter 10,
D.2). There are some differences ASTME112-1996 with ISO 643-2003 standard, but this standard citations
There is no technical difference between the two standards.
● use equivalent to international standards GB/T 10123-2001 instead of ISO 8044.1999 (see Chapter 3).
--- With steel and alloy Grade unified digital code (ISC) instead of metal and alloys unified digital numbering system (UNS) (see
Chapter 11).
This standard made the following editorial changes.
--- Delete international standard directory, foreword and introduction;
--- Delete Chapter 1 appendix C for a description;
Appendix D --- delete references ASTM G108 reference, direct reference to ASTM G108-1994 as 9.2

Corrosion of metals and alloys
Bicyclic electrochemical potentiodynamic reactivation measurement methods
1 Scope
This standard specifies the use of bicyclic electrochemical potentiodynamic reactivation (DL-EPR) test evaluation stainless steel and nickel-based alloys sensitization degree
(DOS) approach.
This standard applies to the grain boundaries or quantitative measurement of alloying elements in the matrix-poor region formed by the impact of adverse thermal effects.
Because sensitized area along the fusion line distribution may be non-uniform, it should be in the test weld HAZ extra attention.
The test results could be used as stainless steel and nickel alloys to intergranular corrosion, pitting potential sensitive indicators and intergranular stress corrosion cracking,
But during the corrosion type of prediction it will also be required for the specific supplementary tests.

3 Terms and Definitions
GB/T 10123-2001 define the following terms and definitions apply to this document.
3.1
Power electricquantity
Passivation process of electricity (Qp) and re-activation of the power (Qr), respectively through the passivation peak and peak power on the reactivation of the calculated curve
The time integral of the flow drawn.
Principle 4
Of corrosion resistant alloy is heat-treated (including welding) appears tiny particles precipitate, such as 304 stainless steel or duplex stainless chromium carbide
Steel σ phase (FeCrMo). The extent of alloying elements in the matrix diffusion is determined by the temperature, when small particles are not formed if the matrix
Diffusion of alloying elements added, will make poor neighborhood of alloying elements. This process is usually referred to as sensitization. Alloying elements poor
Regional poor corrosion resistance, but also prone to stress corrosion cracking, expansion of the extent of this failure mechanism depends on the degree of alloying elements and poor
Alloying elements poor density region. Therefore, a simple test method to quickly determine whether stainless steel and nickel-based alloys have the potential
Harmful thermal effects. Electrochemical potentiodynamic reactivation test (EPR) was developed for this purpose. Currently both laboratory applications electrification
Learn potentiodynamic reactivation test methods are monocyclic and bicyclic Law Act. Single Tour de France despite ranging from the passive state to the activated state of polarization
Scanning, but there are too sensitive to the degree of surface finish shortcomings. After assembly of the cell and may be appropriately improved electrochemical potentiodynamic
Reactivation test (EPR) is also applicable to field test.
