CETP0000-L-467全球实验室加速循环腐蚀试验.doc

1.0 introduction 介绍 1.1 TEST SCOPE 试验范围 This standard specifies an accelerated laboratory atmospheric corrosion test. The testing environment addressed is similar in effect to that of the salt load/ climatic part of the proving ground corrosion test procedure, CETP 00.00-R-343 and yields corresponding results. The objective of the test is to allow evaluation of the corrosion resistance of metals in environments where there is a significant influence of chloride ions, mainly as sodium chloride from a marine source or by winter road de-icing salt. The laboratory test provides full exposure to the salt load and humidity environment. It does not attempt to simulate other engraving factors such as mud loads, temperature stresses or wear. It serves as a general purpose atmospheric corrosion test and applies to a variety of materials, coatings, and interactions of materials, both as test specimens or in designed components. The test can be used as a design verification method in order to (a) develop and qualify new corrosion resistant products, (b) develop new pre-treatments and finishing processes, (c) select materials and, (d) perform quality control of the final product. 本标准是关于一项在实验室里加速进行的大气腐蚀试验。本文所述的试验环境类似于《试验场腐蚀试验程序CETP00.00-R-343》中的盐负荷/环境影响部分，得出相应的结果。试验目的在于评估金属在富含氯化物的环境中（主要是海水中的盐或冬天用于融雪的盐）的抗腐蚀性。该实验室试验主要是将试验件完全暴露在湿润的盐负荷环境中，而非模拟其他摩擦因素如泥负荷、温度压力或磨损。该试验主要作为一项大气腐蚀试验，适用于各种各样的材料、涂层、试样或设计零部件材料的相互作用。该试验可作为一种验证设计的方法，用于(a)开发并验证新的抗腐蚀产品；(b)开发新的预处理和表面处理工艺；(c)选择材料；(d)对最终产品的质量控制。 The standard specifies controlled conditions for equipment and procedures to allow the test to be performed with a high degree of repeatability and reproducibility. It is designed to be suitable to run in various climate chambers, either as a fully automated procedure or with partial manual operations. 本标准说明了设备和程序的受控条件，让实验具有高度的重复性和再现性。本标准适用于多种环境试验箱，包括全自动试验或部分手动操作的试验。 1.2 SUMMARY OF TEST CONTENT 试验内容摘要 The workday test procedure consists of: 工作日的试验程序由以下几个方面组成： A 6 h wet phase at room temperature. with inte
