Non-destructive tests have been increasingly used in historic buildings not only for pre-restoration investigation but also as useful tools to evaluate the effectiveness of eventual interventions. These tests can complement and supplement destructive tests like laboratory analysis of extracted samples as long as a sound sampling plan has been put in place to commensurate with the pattern and extent of dilapidation and materials distribution. Common methods employed in projects in Singapore and Malaysia include the infrared thermography, ground penetrating radar, microwave moisture tomography and ultrasonic pulse echo tomography. The paper discusses about a selection of case studies, demonstrating the application of various techniques for the identification of hidden details, defects and deterioration, and moisture detection.

无损检测在历史建筑诊断中的应用：来自新加坡和马来西亚的案例研究

无损检测已越来越多地用于历史建筑中，不仅用于恢复前的调查，而且还用作评估最终干预措施有效性的有用工具。这些测试可以补充和补充破坏性测试，例如提取样品的实验室分析，只要已制定合理的采样计划以与破损的形式和程度以及材料分布相称即可。在新加坡和马来西亚的项目中，常用的方法包括红外热成像，探地雷达，微波水分层析成像和超声脉冲回波层析成像。本文讨论了一些案例研究，论证了各种技术在识别隐藏细节，缺陷和恶化以及水分检测中的应用。
