标准摘要
[中文适用范围]： ISO 28706 的这一部分描述了测定玻璃和搪瓷制品在 25 °C 至 95 °C 温度下耐碱性液体侵蚀的测试方法。 所使用的设备是一个圆柱形容器，其中仅测试一个搪瓷样品。 注 1：该测试方法最初是为了测定搪瓷和瓷釉对热氢氧化钠溶液的耐受性而制定的。 在ISO 28706本部分的范围内，可以测试其他碱性液体的电阻。 注2：ISO 28706的这一部分使用圆柱形容器，通常用于对化学工业的玻璃质和搪瓷涂层进行测试。 [外文原描述]： ISO 28706-4:2016 describes a test method for the determination of the resistance of vitreous and porcelain enamelled articles to attack by alkaline liquids at temperatures between 25 °C and 95 °C. The apparatus used is a cylindrical vessel in which only one enamelled specimen is tested. NOTE 1 The test method was initially set up for determination of the resistance of vitreous and porcelain enamels to a hot sodium hydroxide solution. Within the scope of this part of ISO 28706, the resistance of other alkaline liquids can be tested. NOTE 2 This part of ISO 28706, which uses a cylindrical vessel, is generally used for tests carried out on vitreous and porcelain enamel coatings for the chemical industry.
