周期性浸泡腐蚀试验标准及相关设备分析

基于产品运输、使用环境的复杂性,单一环境因素模拟已不能满足产品测试需求。溶液浸泡腐蚀试验是一种常见的环境试验,目前,其试验形式除单一的溶液浸泡外,周期性浸泡腐蚀试验也逐步开展。对此,GB、TB、ISO、PSA、ASTM等相关标准给出了规定要求和试验方法,在此基础上为满足其要求相应的试验装置也逐步开始开发和应用。基于不同标准和现有试验设备对周期性浸泡腐蚀试验进行分析讨论,得出各个标准的不同适用范围和试验条件,并针对其原理共性提出开发通用性设备的展望,为浸泡腐蚀试验标准的选取及试验装置的开发提供参考意见。

Analysis on Standards and Related Equipments for Periodic Immersion Corrosion Test

Based on the complexity of the product transportation and the use environment, the simulation of single environmental factors can’t meet the requirements of product testing. Solution immersion corrosion test is a common environmental test. At present, in addition to the single solution immersion, the periodic immersion corrosion test is gradually carried out. In this regard, GB, TB, ISO, PSA, ASTM and other related standards are given the requirements and test methods. On these basis, in order to meet the requirements, the corresponding test device has gradually begun to develop and application. In this paper, based on the different standards and present equipment, the periodic immersion corrosion test is analyzed and discussed, obtaining the applicable scope and test conditions of each standards and putting forward the prospect of developing universal equipment according to the generality of the principle, providing reference for the selection of immersion corrosion test standards and the development of test equipments.
