Foreword

This standard was drafted in accordance with GB/T 1.1-2009 given rules. The standard proposed by China Iron and Steel Association. This standard by the National Steel Standardization Technical Committee (SAC/TC183) centralized. This standard is drafted by. Wuhan Iron and Steel (Group) Company. The main drafters.

Introduction

Enameling cold-rolled steel scales blast susceptibility testing method generally comprises hydrogen permeation and enamelling law, this standard uses a hydrogen permeation measurement scales steel Explosion sensitivity. Enameling cold-rolled steel scales explosion sensitivity test Hydrogen permeation method

1 Scope

This standard specifies the dual cell assay enameling cold-rolled steel scales explosive hydrogen permeation test principle sensitive method, test equipment and electronic Hydrolyzate, samples, test procedures, and test results of the calculation reports. This standard applies to a thickness of 0.3mm ~ 3.0mm enamel sensitivity was measured using cold-rolled steel scales explosion. Principle 2 When charging hydrogen electrolysis, hydrogen ions (H) to reach the surface of the specimen as a cathode, to become a hydrogen atom into the sample, the sample surface to the other diffusion time, Re is a hydrogen atom electrolytically oxidized into hydrogen ions (H), by detecting the anode current of hydrogen oxidation process, to assess the hydrogen atoms in the sample Diffusion process. When the time required for the diffusion of hydrogen called stable hydrogen permeation time tb, tb longer, anti-enamel scale burst performance, the better. by tb defined sample anti-enamel scale explosion sensitivity TH.

3 Chemicals

Chemicals used in the test were of analytical grade, test water is deionized water.

4 test device and the electrolyte

4.1 test device Test device shown in Figure 1, the specimen is clamped between two cells A and B are not mutually connected. A termination galvanostat, B termination constant potential , Automatic recording current variations are oxidized after permeation through the data collection system. ......
