Soluble salts play a key factor in damage to a variety of materials, including stone, ceramics and metals. Particularly, salt contamination can lead to weakening of porous materials through salt crystallisation events, and increases the rate of metal corrosion. Over time, this results in physical damage to affected objects and buildings. It is therefore important to be able to monitor the salt content of materials, in order to understand levels of salt contamination and the potential for damage to occur. This research discusses the further development of the testing method for surface chlorides originally proposed by Piechota and Drake Piechota (2016) in their article “A simple survey kit for chloride detection on cuneiform tablets and other collections”. It introduces new and revised steps into the original protocol in order to make the achieved results semi-quantifiable, as well as identifying the limits of detection of the test kit. A comparison to alternative testing methods showed that comparable results were achievable using this methodology. The revised methodology was tested for efficacy on a range of salt contaminated objects, as well as on samples from buildings.

检测物体和建筑物的氯化物污染–评估新的测试过程

可溶性盐是损坏各种材料（包括石材，陶瓷和金属）的关键因素。特别地，盐污染可通过盐结晶事件导致多孔材料变弱，并增加金属腐蚀速率。随着时间的流逝，这会对受影响的对象和建筑物造成物理损坏。因此，重要的是能够监视材料中的盐含量，以了解盐污染的程度以及发生损坏的可能性。这项研究讨论了Piechota和Drake Piechota（2016）最初在其文章“用于楔形文字片和其他收藏品中检测氯的简单调查工具”中提出的表面氯化物测试方法的进一步发展。它在原始协议中引入了新的和经过修订的步骤，以使获得的结果可以半定量，并确定检测试剂盒的检测极限。与替代测试方法的比较表明，使用这种方法可以达到可比的结果。测试了修订后的方法论对一系列盐污染物体以及建筑物样本的功效。
