代表美国能源部对反射式隔热产品和系统进行的评估表明，有许多重要的短期和长期问题以及与其热性能相关的问题需要解决。具体的短期建议包括对实验室方法进行详细研究，目的是确定当前方法和分析技术的制约因素，并扩大现有数据库。 将描述为解决这些问题而制定并正在实施的详细计划。这涉及一系列大约100个防护热箱（ASTM C 236）试验，这些试验将在具有良好特性的试验板上进行，试验板包含反射绝缘材料和典型产品。所有测试面板将包含额外的内部温度仪表，以便从系统测试结果中获得有关反射绝缘材料实际热性能的必要信息。 实验矩阵包括测量空气空间平均温度和温差、空腔发射度和纵横比、螺柱热阻、热流方向以及单个空腔内多个空气空间之间相互作用影响的测试。引用:研讨会，ASHRAE Trans。，第95卷，第。2.

An assessment of reflective thermal insulation products and systems, carried out on behalf of the Department of Energy, indicated that there were a number of significant short- and long-term issues and problems relating to their thermal performance that needed to be addressed. The specific short-term recommendations included the establishment of a detailed study of laboratory methods with the objectives of identifying constraints of current methods and analytical techniques and providing an expansion of the existing data base.The detailed program, which has been devised and is currently being carried out to address these issues, will be described. This involves a series of approximately 100 guarded hot box (ASTM C 236) experiments to be performed on well-characterized test panels containing reflective insulation materials and typical products. All test panels will contain additional internal temperature instrumentation so that the necessary information regarding the actual thermal performance of the reflective insulation material can be obtained from the results of the systems test. The experimental matrix includes tests to measure the effect of airspace mean temperature and temperature difference, cavity emittance and aspect ratio, stud thermal resistance, heat flow direction, and the interaction between multiple airspaces within a single cavity.
