标准范围

ISO 7326:2006规定了确定软管外盖耐臭氧性的五种方法:方法1，对于孔尺寸高达并包括25mm，在软管本身上进行；方法2，对于大于25mm的孔尺寸，在来自软管壁的测试件上进行；方法3，对于大于25mm的孔尺寸，在来自盖的测试件上进行；方法4，对于所有孔尺寸，在软管本身上执行；方法5，对于所有孔尺寸，在可膨胀软管上进行，例如织物增强软管。

ISO 7326:2006 specifies five methods for determining the ozone resistance of the outer covers of hoses:

• method 1, for bore sizes up to and including 25 mm, carried out on the hose itself;
• method 2, for bore sizes greater than 25 mm, carried out on a test piece from the hose wall;
• method 3, for bore sizes greater than 25 mm, carried out on a test piece from the cover;
• method 4, for all bore sizes, carried out on the hose itself;
• method 5, for all bore sizes, carried out on hoses that are expandable, for example textile-reinforced hoses.
