标准摘要
[中文适用范围]： ISO 20492 的这一部分规定了玻璃隔热单元边缘密封强度的测试方法，以及部分测试密封剂的水分和气体渗透性的方法。 ISO 20492 的其他部分指定了中空玻璃单元标准化的两种方法：方法 1 适用于北美等市场；方法 2 适用于北美等市场。 方法 2 旨在用于欧洲等市场。 ISO 20492 本部分中的方法仅适用于 ISO 20492 其他部分中定义和使用的方法 2。 如果边缘处没有针对直接紫外线辐射的保护，例如结构密封胶玻璃系统，则有必要遵循附加的欧洲技术规范。 参见参考文献[4]和[5]。 [外文原描述]： ISO 20492-4:2010 specifies methods for testing the edge seal strength, and partially testing the moisture and gas permeation through sealants, of glass insulating units. Other parts of ISO 20492 designate two approaches to the standardization of insulating glass units: approach 1 is intended for use in markets such as North America; and approach 2 is intended for use in markets such as Europe. The methods in ISO 20492-4:2010 are applicable only to approach 2, as defined and used in the other parts of ISO 20492. In cases where there is no protection against direct ultraviolet radiation at the edges, such as structural sealant glazing systems, it is necessary that additional European technical specifications be followed.
