标准摘要
[中文适用范围]： 本国际标准规定了适用于测试玻璃和瓷釉涂层的样品的制作方法。 它规定了两种不同的样本： ——取自生产物品的样本； ——专门制作的标本。 注：当要定量测定搪瓷涂层单位面积的质量损失时，只能使用专门制作的样品，因为从搪瓷制品上切下的样品会降低测试方法的准确性。 [外文原描述]： ISO 28764:2015 specifies a method for the production of specimens suitable for testing vitreous and porcelain enamel coatings. It specifies two different specimens: - specimens taken from production articles; - specially produced specimens. NOTE Only the specially produced specimens can be used when the loss in mass per unit area of the enamel coating is to be determined quantitatively, as specimens cut from enamelled articles can reduce the accuracy of the test method.
