ISO 20492-4:2010规定了玻璃绝缘装置边缘密封强度的测试方法,以及通过密封剂的水分和气体渗透的部分测试方法。ISO 20492的其他部分指定了两种中空玻璃单元标准化方法:方法1用于北美等市场;方法2计划用于欧洲等市场。
ISO 20492-4:2010中的方法仅适用于ISO 20492其他部分中定义和使用的方法2。
如果边缘没有防直接紫外线辐射的保护,如结构密封胶玻璃系统,则有必要遵循其他欧洲技术规范。
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.
