标准摘要
[中文适用范围]： 本部分ISO 20492建立了两种通过气候测试测试中空玻璃单元边缘密封耐久性的方法。这两种方法分别指定为适用于北美等市场的“方法1 以及适用于欧洲等市场的“方法2 。本部分ISO 20492适用于预组装、永久密封的中空玻璃单元，具有一或两个空气层，并带有故意留空以平衡单元内部与周围大气压力的毛细管。本部分ISO 20492不适用于包含花格玻璃涂层的中空玻璃单元。本部分ISO 20492不适用于仅具有装饰功能的中空玻璃（IG）单元。 [外文原描述]： ISO 20492-1:2008 establishes two methods for testing the durability of edge seals of insulating glass units by means of climate tests. The two methods are designated as approach 1 for markets such as North America and approach 2 for markets such as Europe. ISO 20492-1:2008 is applicable to pre-assembled, permanently sealed, insulating glass units with one or two airspaces, and with capillary tubes that are intentionally left open to equalize pressure inside the unit with the surrounding atmosphere. ISO 20492-1:2008 is not applicable to sealed, insulating glass units that contain a spandrel glass coating. ISO 20492-1:2008 does not apply to insulating glass units whose function is decorative only.
