在建筑行业中，玻璃的强度对玻璃构件的尺寸起着重要的作用。在这里，除了支撑条件、加载率、相对湿度等参数起重要作用外，玻璃的划痕损伤也决定了玻璃的断裂强度。损坏后的热处理可能会影响玻璃的强度。热处理温度，特别是升高到玻璃化转变温度，与断裂应力之间的相关性已经由不同的研究人员通过几种方法对样品进行预处理和测试设置进行了研究。本文系统地介绍了在样品预处理框架内进行的各种初步研究，以研究预损伤样品的热处理对断裂应力的影响。为此，在室温下对预损伤、热处理的钠钙硅酸盐玻璃试样进行了双环弯曲试验。研究的目的是估计强度试验前的热处理对钠钙硅酸盐玻璃断裂强度的影响程度。考虑了热处理温度、试样在炉内停留时间及炉内设计等参数。结果表明：作为浮法玻璃的钠钙硅酸盐玻璃，由于假定热处理过程中预损伤的愈合，其断裂应力显著增加；
The strength of glass plays an important role in the dimensioning of glass components in the building industry. Here, not only parameters such as support conditions, loading rate, relative humidity etc. play an important role, but the damage by means of scratches also determines the fracture strength of glass. A heat treatment after damaging may have an influence on the resulting glass strength. The correlation between heat treatment temperature, and in particular elevated temperatures up to the glass transition temperature, and fracture stress has been studied by different researchers with several approaches of pre-treatment of specimens and test setups. This paper methodically presents various preliminary investigations which were carried out within the framework of the pre-treatment of the samples in order to investigate the influence of heat treatment of the pre-damaged samples on the fracture stress. For this purpose, double ring bending tests were performed at room temperature on pre-damaged, heat-treated soda–lime silicate glass specimens. The aim of the investigations is to obtain estimates of the extent to which a heat treatment prior to the strength test influences the fracture strength of soda–lime silicate glass. Parameters like the heat treatment temperature, the dwell time of the samples inside the furnace and the furnace design were considered. The results show that the heat treatment can increase the fracture stress of soda–lime silicate glass as float glass significant due to an assumed healing of the pre-damage during heat treatment.
